Installing the Software
Version 4.0
06/25/07
Chances are that you already know this part but …
Installing from CD ROM
Insert the CD ROM in your CD Drive. If the installation program does not auto-start, then go
to the CD ROM drive and dbl-click on the only executable file in the root directory of the CD.
If you are presented with a choice of products, select the DIGIVIEW software and follow the
prompts to complete the installation. All of the defaults offered are acceptable but you may
over-ride any of them you want.
Installing from a WEB Download
If you downloaded the software from our web site, double-click on the file you downloaded to
launch the self-extracting install program. Follow the prompts to install the software. All of the
defaults offered are acceptable but you may over-ride any of them you want.
ðððMAKE NOTE OF THE DESTINATION DIRECTORY (the default is c:\program
files\Techtools\DigiView.)
You will need to know this when Windows installs the USB drivers.
1.1
Installing the USB Drivers
Windows handles installing the USB drivers the first time you connect the DigiView to your
system.
1. MODEL DV1-100 - Plug DigiView into a POWERED HUB (one with its own power
supply) or directly into a USB port on your PC. You CAN NOT use a bus-powered hub; it
can not provide enough power to operate the DV1-100.
2. When the Windows 'New Hardware Wizard' starts, select 'NEXT' until it prompts you for the
driver location.
3. If you are installing from CDROM, select the 'SEARCH CDROM' option. Otherwise, select
the 'search specific path' option and enter the path to the install directory noted above
(default: c:\program files\techtools\digiview).
4. Click NEXT and Windows will install the drivers.

Configuration
The DigiView software is designed to make configuration an easy task and less time consuming
than most PC based analyzer systems. The easier it is configure and understand your Capture
and Analysis tool, the easier it will be to achieve successful results.
Configuration options can be accessed by using the CONFIG menu.
The first topic in this section covers the physical channel connections and cable color scheme.
The next section provides detailed information on defining trigger conditions and associating a
signal type with the physical channels. The last two sections deal with user preferences.
•Connecting Data Lines
•Defining Signals and Triggers
•Analyzer Options
•Color Themes
•Environment Options
2.1
Connecting the Data Lines
The DigiView data cable has 18 data lines and 2 grounds. These are partitioned into 2 identical
groups. Each group has a ground and 9 data signals. The leads are color-coded. Black is
ground, brown the first data signal and so on in standard resistor color-code order. The second
group of signals is identical.
The figure below shows a physical layout of the cable, the data line definitions and the color
codes. This figure is available by clicking the PINOUT button in the "Edit Triggers & Signals"
window (selected from the CONFIG menu). This opens a non-modal window so you can leave it
open while you work if desired.
The data cable is made of high quality, extremely flexible wire and high quality connectors. It is
expensive so please remember your mom's advice and pull on the connectors; not the wires.
The connectors are designed to mate to .025 square posts and can be side-stacked on 100mil
centers, making them ideal for direct connection to standard square post connectors.

Configuration

Additionally, they mate firmly with the included micro-grabber hooks for connecting to IC leads.
The DigiView DV1-100 hardware is designed to monitor digital logic signals in the 0 to 5V range
and Model DV3400 is designed for signals in the -50 to 50V range. Standard overshoots and
undershoots common to digital systems will not harm it. The data lines have extra static
protection circuits, current limits and impulse suppression. However, mishandling could still
damage them. Simply treat them like you (should) treat your valuable one-of-a-kind target and
DigiView will give you years of service.
2.2
Defining Signals and Triggers
The hardware will ignore any data lines that are not defined as part of a waveform or part of a
trigger. This prevents unused signals from eating up the sample buffer space, even if they are
connected to active signals. Waveforms that are DEFINED but disabled, will be captured but not
displayed.
DigiView uses real-time hardware compression to greatly extend its capture buffer. Most data
you are likely to monitor lends itself well to our compression technique. Compression ratios of
100:1 are common. With sparse data, compression ratios of over 200,000:1 are achievable.
Since the degree of compression depends on the amount of activity, you will achieve maximum
compression if you only define signals of interest. DigiView model DV1-100 ALWAYS samples at
a 100MHz rate and Model DV3400 has a selectable sample mode of 200MHz or 400MHz.

Triggers
2.2.1
Signals
The DigiView DV1-100 hardware has 18 physical channels and the DV3400 can be configured
for 18 or 36 channels. However, we like to think in terms of symbolic names representing
individual signals (clock,ALE) or groups of signals (DataBus, Address) rather than channel
numbers(0,1,2..). We start by defining SIGNALS in terms of CHANNELS. This is the only place
we deal directly with physical channels. The remainder of the software deals in terms of signal
names rather than channel numbers. When we define signals, we are mapping a signal NAME to
one or more physical channels.
Click on one of the "Define New Signal" buttons to create a new signal. After Selecting the signal
button, a new signal of the chosen type will be created and it's property editor will appear. You
can rename the signal, change the channels to use for this signal definition and set all associated
options from this editor. (For details on signal options, see the section: Signal Editors)
The main purpose of the signal section of the config screen is to provide an overview of all
current signal definitions and their related channels. You can also Add, Edit or Delete signals
from this screen, determine each signal's type, its basic colors and its enabled status.

DigiView User's Guide
The configuration screen is arranged in a grid with columns representing the physical
channels and one row per defined signal.
Channel 0 is in the farthest right column and channel 17 (or 35) is in the farthest left column (as
marked in the header.) Light blue lines appear every 4th channel (or nibble).
In addition to the color references at the top of the window, you can click on the 'pin-out' button to
see a physical layout of the channel connector, with color codes.
Note that it is important to enable only channels that are actually being connected to your circuit.
The remaining, unconnected channels will be floating and will most likely pick up noise or power
line hum. If enabled, these transitions will get stored, wasting storage space. It is also important
to connect the black ground wires to your target's ground so that the analyzer and the target have
a common ground reference.
Changing the Signal order When adding a large number of signal definitions, you may want to change some of their
positions to organize or group related signals. To change the display order, grab the small
handle in the left margin with your mouse and drag the definition to a new position.
Signal Name The name of this signal definition. This value can be changed by editing the signal's properties.
(see: Signal Editors)
Signal Colors and Type ,
,
, etc.
You can see the color of a signal and determine the type by the graphical indicator displayed to
the right of the channel indicators. Each signal type will display a unique graphic with
representative colors.
Delete Signal You can delete a signal definition by clicking on the 'X'.
Edit Signal Properties You can change the properties of a signal definition by clicking this button. (see: Signal Editors)
Enabled Status Indicates the enabled state of the signal. When the lightbulb is ON, the signal is enabled. Click
this button to toggle the "enabled" status of the signal. This value can also be changed by
editing the signal's properties. (see: Signal Editors)
Associated Channels All channels associated with this signal definition will be indicated in this display as a blue "dot".
Channel 0 is in the farthest right column and channel 17 (or 35) is in the farthest left column (as
marked in the header.) Light blue lines appear every 4th channel and non associated channels

appear as '-' as a reference. Also, colored squares at the top show each channel's wire color.
Notice that there are only 9 colors so the color sequence repeats (channels 0 and 9 are both
brown).
2.2.1.1
Signal Editors
DigiView provides several "Signal" type definitions which allow unique methods of interpreting
and displaying the raw data captured on the logic channels. Each Signal type has a unique editor
with relevant options for its type. From the editor you will also assign some of the physical logic
channels to be used for this new signal definition. (see: Signals, Connecting Data Lines)
You may choose to repeat the use of some channels in multiple Signal definitions in order to
interpret the data differently and gain a perspective that is relative to your current point of interest.
This can be done easily by creating a new Signal using the definition with the properties you
require. Using the same channels in multiple definitions will not have any effect on the actual
capture, but can greatly increase your ability to analyze the data and present visual
representation to others.
NOTE: For your convenience, the signal editors display a darker background on channels that
are already assigned to other signals. However, the same channel can be assigned to as many
signal definitions as you need. For instance, if you want to capture the Read and Write cycles of
an SPI bus, you can create 2 Synchronous Serial signals and assign the same channel as the
Clock for each definition.
The currently available Signal Types are listed below. Details of each type's properties are
described in the following sections.
•Boolean - single channel viewing.
•Bus - multi-channel viewing.
•Asynchronous - serial UART analysis, pre-selected and custom baud rates, channel
inversion option, from 4 to 8 bit selectable, parity option.
•Analog - multiple channels combined to a single analog view.
•I2C - Complete I2C protocol analysis. 7bit/10bit addressing, High Speed Mode Master
Codes, General Call support.
•State - Filters multi-channel data by state of a single channel, selectable CLK/DATA
inversion, selectable transition state of Rising/Falling/Both, additional Enable channel for
filtering.
•Synchronous - from 1 to 32 bit protocols, suitable for SPI analysis, selectable CLK/DATA
inversion, selectable Rising/Falling/Both clock edges, LSB/MSB selection, additional Enable
channel for filtering and synchronizing.

2.2.1.1.1 Boolean
The Boolean Signal is the most common method of viewing captured data. Boolean Signals
provide viewing of the logic level of a single channel at any given point in time.
Signal Name - Change the text displayed here to help you identify this signal definition. If the
name has already been used, it will automatically be appended with a numerical value in
brackets (i.e. [2]). The name displayed here will be used in the Waveform Views, searches,
tables, lists (if applicable), exports and all menu references.
Color Selection & Examples - If this signal definition has multiple Wave Form viewing
modes, an example of each mode is displayed in the current color scheme, followed by a
listing of any items that allow custom colors (i.e. Signal Color, Signal Background). Click on
an item in the list to select a new color.
Enable Signal Channels - This item is selected (checked) by default. Uncheck this item to
completely disable the Signal Definition. It is recommended to disable any signals that use
channels that are not connected to a physical device. When a capture takes place ("Run"),
any channels that are assigned to disabled signals will be ignored instead of using valuable
capture space.
Invert Signal Value - This item is de-selected (unchecked) by default. Check this item to

have the value of the captured channels "inverted" before processing or displaying for this
signal definition. This setting will not effect any other signal definitions that may use the
same channels.
Channel Selection - This is where you will associate a signal definition with the physical
channels or connections to the outside world. Each signal definition type will have one or
more channel selection groups and will allow one or more channels to be selected for each
group. Each channel selection group will be identified on its left if more than one group is
available for the signal type.
To select a channel, click on the " - " below the proper color (and channel number) that
corresponds to the physical connection of the DigiView Cable (see: Connecting the Data
Lines). Channels that are selected for this signal will replace the " - " with a blue "dot" as
shown above. Channels that are already defined in other signal definitions will have a
darker color around the selection area for the channel (as all of the channels do in the
graphic above).
Reset Colors - This button will reset the colors for this signal so that they will match the
currently selected color theme (see: Color Themes).

modes, an example of each mode is displayed in the current color scheme, followed by a
listing of any items that allow custom colors (i.e. Signal Color, Signal Background). Click on
an item in the list to select a new color.
Communication Settings - The current communication settings for the decoder are
displayed in the order of Baud Rate, Data Bits and Parity. To change these items, use the
appropriate property editors below. Each signal definition has its own decoder, so these
settings will not affect other Synchronous signal definitions.
Baud Rate - Select from one of the pre-defined baud rates or select "Custom" to enter a
non-standard rate. Custom rates should be specified fully (i.e 115.2K should be specified
as 115200 Baud) as shown in the Custom box above.
Data Bits - Select the number of DATA bits in the packet. Options are from 4 to 8 bits.
Parity - Choose the desired parity. Options are NONE, ODD, EVEN, ONE, ZERO.
Sync Start of Packet - Use this button to synchronize to the beginning of the first packet in
the captured data. Normally this is unnecessary unless DigiView can not automatically find
the beginning of a packet in the data captured. Right-Click on the button to advance the
decoder by one bit and Left-Click to backup by one bit. Click multiple times or hold the
button down to repeat the action. The decoders "shift-bit" action is performed in a circular
fashion and is limited to the number of bits required for a single packet. The numerical
display to the right of the button tracks the bit position from the beginning of the available
data.
Enable Signal Channels - This item is selected (checked) by default. Uncheck this item to
completely disable the Signal Definition. It is recommended to disable any signals that use
channels that are not connected to a physical device. When a capture takes place ("Run"),
any channels that are assigned to disabled signals will be ignored instead of using valuable
capture space.
Invert Signal Value - This item is de-selected (unchecked) by default. Check this item to
have the value of the captured channels "inverted" before processing or displaying for this
signal definition. This setting will not effect any other signal definitions that may use the
same channels.
Channel Selection - This is where you will associate a signal definition with the physical
channels or connections to the outside world. Each signal definition type will have one or
more channel selection groups and will allow one or more channels to be selected for each
group. Each channel selection group will be identified on its left if more than one group is
available for the signal type.
To select a channel, click on the " - " below the proper color (and channel number) that
corresponds to the physical connection of the DigiView Cable (see: Connecting the Data
Lines). Channels that are selected for this signal will replace the " - " with a blue "dot" as

2.2.1.1.4 Analog
The Analog Signal also provides viewing of multiple channels as a single value, but displays this
value as a proportional value in the Wave Form views. The waveform height will be the value of
all the channels, proportional to the maximum numerical value of the number of channels
chosen.
The chosen channels do not have to be consecutive. Any "skipped" channels in this definition will
be ignored and the selected channels "packed" to form the bits of a single value. The lowest
selected channel will be the least significant bit (LSB). In the graphic below, channel 0 is the LSB
and channel 7 is the MSB.
Signal Name - Change the text displayed here to help you identify this signal definition. If the
name has already been used, it will automatically be appended with a numerical value in
brackets (i.e. [2]). The name displayed here will be used in the Waveform Views, searches,

another channel changes. This other channel will be used as a "state clock" and optionally the
Clock can be qualified by the logic state of an additional channel (Enable). This signal type can
be used to mask invalid data during bus transitional periods or the "noise" that occurs during
unqualified periods, making it easier to analyze true data.
Signal Name - Change the text displayed here to help you identify this signal definition. If the
name has already been used, it will automatically be appended with a numerical value in
brackets (i.e. [2]). The name displayed here will be used in the Waveform Views, Searches,
Tables, Lists (if applicable), Exports and all menu references.

Color Selection & Examples - If this signal definition has multiple Wave Form viewing
modes, an example of each mode is displayed in the current color scheme, followed by a
listing of any items that allow custom colors (i.e. Signal Color, Signal Background). Click on
an item in the list to select a new color.
Qualifier - These settings determine how the data of the selected channels will be be
decoded. To change these items, use the appropriate property editors below. Each signal
definition has its own decoder, so these settings will not affect other signal definitions.
Clock Edge - Choose the transition state of the Clock channel that determines when the
data channels are "valid". Options are FALLING, RISING, BOTH. Whenever the Clock
channel transition matches the selection, the data channels will be decoded. Set this option
to "Both" to decode the data on every transition of the Clock channel.
Enable State - Choose the logic level of the Enable channel that determines when the
clock channel is "valid". Options are LOW, HIGH, IGNORE. Whenever the Enable channel
matches the indicated state, the clock and data channels will be decoded. Set this option to
"Ignore" if these channels are always valid and you do not wish to use the Enable channel
as a qualifier.
Enable Signal Channels - This item is selected (checked) by default. Uncheck this item to
completely disable the Signal Definition. It is recommended to disable any signals that use
channels that are not connected to a physical device. When a capture takes place ("Run"),
any channels that are assigned to disabled signals will be ignored instead of using valuable
capture space.
Invert CLK/Data - These items are de-selected (unchecked) by default. Check these items to
have the value of the associated channel "inverted" before being decoded. This setting will
not affect any other signal definitions that may use the same channels.
Channel Selection - This is where you will associate a signal definition with the physical
channels or connections to the outside world. Each signal definition type will have one or
more channel selection groups and will allow one or more channels to be selected for each
group. Each channel selection group will be identified on its left if more than one group is
available for the signal type.
To select a channel, click on the " - " below the proper color (and channel number) that
corresponds to the physical connection of the DigiView Cable (see: Connecting the Data
Lines). Channels that are selected for this signal will replace the " - " with a blue "dot" as
shown above. Channels that are already defined in other signal definitions will have a
darker color around the selection area for the channel (as all of the channels do in the
graphic above).
CLK - Select a channel to decode as a CLOCK to qualify the Data.
Data - Select one or channels to decode as the DATA.
Enable - Select a channel to qualify the CLOCK.
Reset Colors - This button will reset the colors for this signal so that they will match the
currently selected color theme (see: Color Themes).

2.2.1.1.7 Synchronous
Use the Synchronous Signal type to see the data from a single channel decoded as a serial
"packet" by using another channel as the bit clock. Optionally you can use the "Enable" channel
to qualify the clock. The decoded data will be displayed as serial packets using the specified bit
count, bit order (LSB/MSB) and Clock edge.

Communication Settings - These settings determine how the data of the selected channels
will be be decoded. To change these items, use the appropriate property editors below.
Each signal definition has its own decoder, so these settings will not affect other
Synchronous signal definitions.
Data Bits - Select the number of DATA bits in the packet. Options are from 1 to 32 bits.
Enable State - Choose the logic level of the Enable channel that determines when the
clock channel is "valid". Options are LOW, HIGH, IGNORE. Whenever the Enable channel
matches the indicated state, the clock and data channel will be decoded. Set this option to
"Ignore" if these channels are always valid and you do not wish to use the Enable channel
as a qualifier.
Clock Edge - Choose the transition state of the Clock channel that determines when the
data channel is "valid". Options are FALLING, RISING, BOTH. Whenever the Clock channel
transition matches the selection, the data channel will be decoded. Set this option to "Both"
to decode the data on every transition of the Clock channel.
Sync Start of Packet - Use this button to synchronize to the beginning of the first packet in
the captured data. Normally this is unnecessary unless you have set the Enable qualifier to
"Ignore". Unlike Asynchronous signals, Synchronous signals do not have a specific bit rate,
so DigiView will not automatically find the beginning of a packet when the qualifier is not
used. Right-Click on the button to advance the decoder by one bit and Left-Click to backup
by one bit. Click multiple times or hold the button down to repeat the action. The decoders
"shift-bit" action is performed in a circular fashion and is limited to the number of bits
required for a single packet. The numerical display to the right of the button tracks the bit
position from the beginning of the available data.
Enable Signal Channels - This item is selected (checked) by default. Uncheck this item to
completely disable the Signal Definition. It is recommended to disable any signals that use
channels that are not connected to a physical device. When a capture takes place ("Run"),
any channels that are assigned to disabled signals will be ignored instead of using valuable

2.2.2
Triggers
You can define a TRIGGER condition. When the hardware detects this condition, it will
'TRIGGER' the logic analyzer. When the sample buffer fills (or you manually STOP it), the data is
transferred to the PC. The software on the PC then displays the data to you.
The trigger point is centered on the screen and is always TIME 0. All data prior to the trigger is
negative time and all data after the trigger is positive time. If you stop the analyzer before a
trigger condition is detected, the approximate center of the collected sample buffer is considered
the trigger and the end of the data is the point where the hardware sampling was manually
stopped.
In this version, the triggers are specified in terms of SIGNALS. After assigning channels to
signal names ( see: Signals), you can configure the trigger condition based on the defined
signals. Most engineers will find it easier to reference the condition as it relates to the circuit's
function rather than remembering which channels of the analyzer were used to connect to
specific signals in the circuit.
DigiView's new trigger configuration screen centers the user's focus on function; making it much
easier to quickly analyze and modify a very complex trigger condition. The following graphic is an
example of an advanced trigger condition for the DV3400.
(see: Trigger Configuration )

Trigger Configuration
The new Trigger Configuration Screen introduces a dual-mode (GUI and text), schematic-like
approach to configuring the matches, sequencers and trigger output from a single window. A text
window shows the 'formula' for the configuration while the 'schematic' shows the flow. These two
sections update together to provide two distinct views of the configuration. Multiple trigger
configurations can also be selected and created using the selection area in the upper left corner
of this screen.
Trigger Configuration Selection
Multiple trigger configurations can be created and stored in the DigiView Data File. Use the
selection box to quickly chose another trigger
configuration. After making a selection, click the "apply" button on the bottom of the screen for the
changes to take affect. To create, copy or rename a configuration, use the icon to the left of the
selection box to open the Trigger Selection Editor.

Trigger Formula (left portion of screen)
The formula presents a summary of the complete configuration. Since this summary can be quite
involved with a complex trigger condition, each section will "highlight" as items in the graphical
section are selected or the mouse moves over them. The formula will automatically scroll to bring
the highlighted section into view while working in the graphical area of the configuration. In the
image above, the summary of "MATCH 2" is brought into view as Match 2 is selected (shown in
blue below).
Schematic (right portion of screen)

This area is where the actual configuration is accomplished.
Every trigger configuration starts with a match condition and ends with Trigger Out, so the work
flow is designed from left to right, starting with the Match Types (see: Match Types).
When the very first Match type is selected and the match condition has been specified, the match
will automatically be routed graphically to the Trigger Out. For Model DV3400, this means it will
route to TERMS 1, then the NON-Sequenced option and then to Trigger Out. This automatic
function is only performed if no other connections already exist. Once you have started making
connections for your trigger configuration, the software will not try to "guess" your intentions.
Since this would hinder your work and cause aggravation, the software allows you to manually
connect or disconnect if the action is valid. Only the obvious connect and disconnects will be
performed automatically.
NOTE: The graphical connections in the trigger configuration directly correspond to the physical
circuit connections in the hardware, making this screen an overview of the resulting logic in the
analyzer's hardware.

2.2.2.1.1.1 Pattern Match
The level trigger is a pattern match detector. You can configure it to match any combination of
0,1 or don't cares across all 18 (or 36) channels. The Pattern Match Editor is displayed below
ADD a Signal - Highlight a defined signal from the left portion of the window and click the "+"
button to add it to the Pattern Match. You can also just "Double-Click" the defined signal to
automatically add it. NOTE: High Level signal definitions (such as State, I2C, or etc) cannot be
added directly as a complete signal. However, the individual portions of the signal (such as
Enable above) can be added in the same manner. To see the sub-portions of a signal, click the
"expand" button in the left column next to the signal's name, then add the sub portions in the
same manner as any other signal.
For instance, if you have defined a State signal like the one above (Address) and you only want
to add the Enable signal to the pattern match, then expand it and double-click on Enable.
Delete a Signal - Highlight a signal in the right portion of the window (or mouse-over its bit
selections) and click the "-" button to delete it from the Pattern Match.
Changing Bit Pattern - Each bit of the signal can be toggled between the 3 states of '0', '1' and

Decimal: Enter any valid decimal value. An Invalid value will be cleared to 0 or assumed to be
HEX.
HEX: Start the value with an "x" or a "0x". If too many digits are entered, the most significant
nibble (leftmost) will be discarded. Any non-HEX digit will be ignored.
Binary: Enter "b" followed by "1's" and "0's". If too many digits are typed, the MSb (leftmost
bit) will be discarded. Any numerical value larger than a "1" or non-numerical character will be
considered a "1".
ASCII: Start the value with a single or double quote.
Duration - Enter the match duration by selecting the units then typing the value. The Maximum
Duration period for Model DV3400 is 5 ms. The Trigger condition will not be considered as "True"
until the entered value for the selected signal has been valid for the indicated duration period.
Identifier - Change the identifier to something meaningful for the match condition if you do not
want the default "Match #" to be displayed in the formula and the graphical configuration area of
the trigger screen.
2.2.2.1.1.9 Less Than or Equal Match
The Less Than or Equal Match type is only available on DigiView Model DV3400.

ADD a Signal - Highlight a defined signal from the left portion of the window and click the "+"
button to add it as the Less Than or Equal Match. You can also just "Double-Click" the defined
signal to automatically add it. NOTE: High Level signal definitions (such as State, I2C, or etc)
cannot be added directly as a complete signal. However, the individual portions of the signal
(such as the DATA portion of a State Signal) can be added in the same manner. To see the
sub-portions of a signal, click the "expand" button in the left column next to the signal's name,
then add the sub portion in the same manner as any other signal.
For instance, if you have defined a Synchronous Serial signal (i.e. SPI) and you want to add the
:Enable portion of the signal to the Greater Than match, then expand it and double-click on
:Enable. It would then appear on the right portion of the editor.
The Less Than or Equal Match type only accepts one signal at a time. After a signal has been
added, the "+" (ADD) button will be disabled (as shown above) until the current signal is
removed.
Delete a Signal - Highlight a signal in the right portion of the window (or mouse-over its bit
selections) and click the "-" button to delete it from the Less Than or Equal Match.
Match Value Format - The value for the Less Than or Equal Match type can be entered in
Decimal, HEX, Binary or ASCII format. The value will be limited to the maximum value allowed for
the selected signal, which will depend on the number of bit positions assigned to the signal. The
formats for entering each value type is described below.
Decimal: Enter any valid decimal value. An Invalid value will be cleared to 0 or assumed to be
HEX.
HEX: Start the value with an "x" or a "0x". If too many digits are entered, the most significant
nibble (leftmost) will be discarded. Any non-HEX digit will be ignored.

DV1-100 Trigger Overview
There are actually two complete trigger circuits in the DV1-100; Pattern (or level) and
Edges. Either of these can be used to specify a trigger or they can be combined (by connecting
both to "TERMS 1") to create a qualified trigger.
When you combine the two trigger circuits, you will get a trigger ONLY if the EDGE detection
trigger AND the LEVEL detectors match at the same time. In other words, we detect the
specified edge(s) while the level pattern matches.
If you deselect everything (no edges or levels specified) or disconnect both trigger circuits, then
the trigger is disabled.

Capturing Data

47
Capturing Data
Once signals and triggers are defined, you can capture a new buffer of data at any time by pressing
the 'Run' button. If you tire of waiting on a trigger or it triggers but you tire of waiting for it to fill up
the buffer, you can STOP or ABORT the capture.
Continuous Run - This will "ARM" the hardware and automatically transfer the data to the
PC repeatedly. This mode is very useful to Monitor signals while making connections. The speed
of the continuous run will vary depending on the PC hardware and the Model of DigiView. With
DV3400, you can adjust the buffer to its smallest setting ( 1%) to have a virtual "LIVE" mode.
RUN - This will "ARM" the hardware and automatically transfer the data to the PC when
the buffer is full. If you do not want to wait for a long capture, you can select the "STOP" button to
force a transfer of the current data captured. If you are waiting on a Trigger condition that you
expected to occur, you can still select the "Continuous Run" button to view the current signal
activity.
STOP - This will halt the capture and transfer whatever was captured to the PC for your
analysis.
ABORT - This will reset the hardware and abort the capture without changing the data
currently being analyzed.
Note that the DigiView hardware is always capturing and storing data in a circular queue. While
you are looking at the last capture, the hardware is pre-filling the buffer up to the 1/2 full point
(DV1-100) or to the buffer size selected (DV3400). When the buffer reaches the pre-fill setting,
the hardware continues capturing and storing data in a circular queue fashion so that the most
recent data is always available but the remaining buffer is still available.
When you click on 'Run', you are actually arming the trigger circuit. Upon trigger, the hardware
allows the buffer to continue past the pre-fill point and to continue filling up (post-fill). Once the
buffer is full, it is transferred to the PC. After the buffer is transferred (or you abort the capture),
the hardware immediately resets and begins pre-filling in preparation for the next capture.

Capture Troubleshooting
Symptom
1. DigiView (DV1-100) Power LED does not
stay ON.
Causes & Solutions
(A). The USB subsystem of the PC is turning
DigiView Off due to a Bandwidth shortage.
REMEDY: Remove other USB devices that
use a port on the same hub (internal or
external).
(B). The USB subsystem of the PC is turning
DigiView Off or DigiView is resetting due to
insufficient power.
REMEDY: If you are using an external hub,
change to a POWERED external hub or
purchase one of better quality that meets USB
specifications.
2. DigiView is only identified as a SERIAL
device by the USB subsystem.
(A). The USB sub-system is experiencing a
problem with corrupted or missing files.
REMEDY: Look for a driver update to the USB
hub (internal or external) or re-install its
drivers. Refresh the DigiView drivers by
re-installing the DigiView software.
(B). Operating System or computer needs
rebooted.
REMEDY: Turn off the computer and re-boot
the system.
(C). The DigiView hardware has been
damaged.
REMEDY: Call Technical Support for repair
information.

Capturing Data
Symptom
3. One of DigiView's channels is connected to
a transitioning signal, but the capture does not
seem to show any activity or very little activity.
49
Causes & Solutions
(A). The resolution of the Waveform View is
too low to see the activity.
REMEDY: Zoom In to see the details of the
activity.
(B). The signal has been defined with the
wrong channel selected.
REMEDY: Edit the signal definition and
change the channel selection. The colors are
repeated for each group of 9 channels, so be
sure to select the correct one.
(C). The signal definition has been "disabled".
REMEDY: Edit the signal definition and
uncheck the Disabled option. The channels
for disabled signals will not appear in the
captured data.
(D). Bad Ground reference.
REMEDY: Connect one of DigiView's ground
wires (black probes) to a ground point as
electrically close as possible to the signal
connections.
(E). Insufficient power, see 1.B above.

Navigating and Analyzing the Data
This is where you spend most of your time; trying to make sense of what you captured. You will
find DigiView software very intuitive and easy to use but it is important to realize that ZOOM
operations occur about the CENTER of the screen. The tools are all designed to take
advantage of this fact to make you more productive.
The general paradigm is to find points of interest, bring them to the center of the screen and then
ZOOM. We provide several methods of finding edges and bringing them to the center of the
screen so that you can zoom in and out without having to constantly scroll to 'zero-in' on the point
of interest.

Waveform Views
Wave Form views are the central focus of navigating and analyzing the huge amount of
captured data. In the waveform views you can Zoom quickly to different resolutions (without
throwing data away), snap to edges or beginning of packets, drop markers to correlate time
between transitions and much more.

Using Cursors and Markers
Markers (or Cursors)
Six markers (A,B,C,D,X,Y) are provided. Markers have several uses. They can be used to
measure time, to 'bookmark' locations and to help bring data to the center of the screen.
The Status window shows the current time of each marker (relative to TRIGGER) as well as
the time between adjacent markers. Whenever a marker becomes the Active Marker, its
corresponding information will automatically highlight in the Status Window. In the image
below, marker "A" is the active marker.

DigiView User's Guide
Drag to place
Simply click on a marker and drag it to the area of interest. You can grab the marker itself
(the vertical line in the waveform area) or its 'flag' (the rectangle at the top of the window).
Notice that the flags are offset so that even when they are overlapped, you can still grab
them. When your mouse is in the capture zone for a marker, the cursor changes to indicate
that it is over a marker. The cursor also indicates which marker would be selected, making it
easier to grab a specific marker when they are very close together (or even on top of each
other).
Quick Select Flags
Sometimes markers are invisible, buried behind other markers or off-screen. You can easily
grab any marker from the quick-select flags at the top right corner of the window, regardless
of their current position or visibility.
Dragging from these flags will bring the marker to the current screen position and make it
visible if necessary.
Clicking on one of these flags will automatically scroll the waveform view to the markers
position and center it in the waveform window. This can also be referred to as "Jump to
Marker".
Auto-Snap
'Snapping' the markers to signal edges makes it easy to measure the time between them or

Navigating and Analyzing the Data
55
to bring a specific edge to the center of the window. This operation is used so often that we
optimized it by making it an automatic function. When you are dragging a marker and your
mouse is over a waveform, the cursor changes to a 'snap-left' or 'snap-right' arrow. The
direction of the arrow shows you which edge (previous or next) of this waveform the marker
will 'snap' to if you were to drop it at that point. The arrow will point to the nearest edge or to
the nearest edge in the direction of mouse movement, even if that edge is off-screen.
If you do NOT want to SNAP, but rather wish to drop the marker exactly at the mouse
position, you can either hold down the control key or move your mouse above or below all
waveforms before releasing the mouse button.
Auto-Snap & Bring to Center
Hold the SHIFT key when 'Snapping' the markers to force the "snapped-to" edge to the
center of the screen.
Drop & Bring to Center
Hold both the SHIFT key and the CTRL key when dragging a marker to "drop" the marker
and bring the drop point and marker to the center of the screen.
Right Click Popup
Right clicking on the name of the signal (or in the top margin) opens a pop-up menu with
easy access selections to bring a marker to the center of the window, or to clear one or more
markers. This provides another method of Setting, Clearing and Jumping to markers. If you
click on the signal's name, then this popup menu will also include signal specific options.
Active Marker
Any action that uses a marker will automatically designate that marker as the "Active
Marker". The active marker exposes additional properties and associated items for easier
navigation and support to 'bring the data to center' concept.
Waveform Association
When you snap a marker to a waveform, it becomes associated with that waveform as
indicated by the reversed color in the Active Marker Column on the right. In the image
below, Marker A is associated with PSEN and the value of PSEN at the marker position is
0X01 as shown in the Active Marker Column.
To associate the Active Marker to another waveform and snap to the next edge of the
waveform, right or left click in the Active Marker Column of the waveform.
© 2007 TechTools
56
DigiView User's Guide
Snap Left/Right
To snap the active marker to the previous or next edge of the associated waveform, either
right or left click in the Active Marker Column or on the dedicated snap button next to the
Active Marker Column's marker identifier. In the image above the identifier is "A" and the
dedicated button is the same color as marker A.
This allows one to walk any marker from edge to edge on a specific signal. To walk
through two different sections of data or two different signals, simply select each desired
marker using the Quick Select flags. Each marker maintains its position, allowing one to
jump back and forth between them. You can walk one signal for a while, jump to the other
marker and walk that signal and then jump back to the first marker and pick up where you
left off.
Left-Click to Snap Left.
Right-Click to Snap right.
Marker Tack
The button just above the Active Marker's snap button will toggle the "Tack" feature of the
marker. When the button is pressed tacking is enabled. When the Tack option is active,
snapping the marker will bring the data to the center of the screen instead of moving the
marker out of view.
You can still drag the marker (with or without auto-snap) to another point in the data, but
when you release the mouse button, the marker AND the data will be brought to the center
of the screen, ready for zooming in/out.
TACKing a marker is particularly useful for walking though a signal, edge by edge.
Normally, when you SNAP the a marker, the marker moves to the previous or next edge of
the associated signal. When the marker is tacked, the DATA is brought to the MARKER
(and the screen center). This allows you to walk through the data without continually
re-centering the screen. It also supports our 'bring the data to the center..THEN zoom'
paradigm.
Note that this is an intelligent TACK. It does NOT freeze the marker at the screen center.
It brings the marker to center any time you move the marker (by dragging, snapping or
setting its position). This allows the marker to stay at a specific TIME/EDGE if you scroll
the screen or jump to another marker. The next time you attempt to move the TACKed
marker, it will move relative to the place you left it, then bring it and the data to the
window's center. For example, we will assume that you have enabled the Tack option for
both X and Y markers. While you are moving/snapping the X marker, it stays as the
center. You can jump to the Y marker and it starts tacking at the center. At any time, you
could jump back to the X marker.
4.3
Marquee Zoom
You can use your mouse to marquee an area of data to zoom in on. Click and drag to marquee a
section. When you release the mouse button, the enclosed area will pan to the center of the

screen and them zoom in as much as possible while keeping the entire area on the screen.
4.4
Toolbar Buttons
We make extensive use of the right mouse button. Most functions have naturally paired
operations. Most paired functions are natural opposites (like left/right, in/out, first/last,
previous/next). Others are not opposites but still naturally paired (like X/Y). We take advantage
of this symmetry to double up the functions of most buttons and other clicks. This not only
reduces desktop usage but also results in more natural, easier to remember functions.
For example, rather than having separate SEARCH LEFT and SEARCH RIGHT buttons, we have
a SEARCH button. Left clicking the button will SEARCH LEFT; right clicking will SEARCH
RIGHT.
After only a few minutes of use, this becomes much more natural than using separate buttons.
Switching directions involves pressing different mouse buttons rather than moving the mouse to a
new button in the application. All buttons in the tool bars to the right of the Waveform Views are
dual-function. Additionally, you will find that left and right clicking on the " < " and " > " symbols,
Active Marker column and various other buttons will perform similarly paired functions.

Bird’s-Eye View
The BirdsEye window gives you the really big picture. It shows the relative zoom and position of
the two waveform windows and the total data. The total data is show with a horizontal line down
the middle and 'goal-post' lines on the ends. The primary waveform window is represented with a
gray rectangle in the top half of the display. Likewise, the secondary waveform window (if visible)
is represented in the bottom half of the window.
When the window is zoomed in on a small percentage of the data (usually the case) the waveform
representation becomes a small circle so that you can still see it. Otherwise it would degenerate
into a very thin line.
As you navigate through the data, you can look at the BirdsEye to see exactly where you are in
the data and how fast you are progressing through it. When you have both waveform windows
open you can see their relative zoom levels as well as positions. If they are linked to each other,
you will notice that they move together through the data.

Each of the markers are also shown with color-coordinated lines.
You can click on the BirdsEye window to position a waveform window in the area of the data
clicked on. If the secondary waveform window is open, then clicking in the bottom half repositions
the secondary waveform. Clicking in the top half repositions the main waveform. If the secondary
waveform is not visible, then clicking anywhere in the window repositions the primary waveform
window.

While most manufacturers provide table views, they generally are not too useful for anything
other than STATE mode signals. Most logic analyzer demos will show data changing on every
sample, making the table view look interesting in timing mode. However, in real usage, most
signals do not change at anywhere near the sample rate, causing the table to show a small
sample of stable data. You might have to scroll several screens before seeing the signal
transition. We have added several enhancements to the basic table view to make them truly
beneficial in real-world usage.
Compressed View
This mode compresses out the 'dead-time' between transitions, packing a lot more
information into a screen of table data. Each line of data in the table contains the
timestamp and the data. The time between lines varies and corresponds to the length of
time the previous sample was stable. In this mode, a 40 line table contains 40 transitions.
In linear (non-compressed) mode, it would contain 40 SAMPLES with perhaps NO
transitions. If multiple signals are added to the table, the compression algorithm takes
ALL signals in to account. A new line is shown any time ANY of the signals change state.
Nothing is lost or thrown away. We simply compress out the redundant information,
making the table hold more significant data. You can switch between compressed and

linear views with a single click at any time.
Although compressed mode is the most efficient way to display a signal in tabular form,
some people have trouble visualizing the non-linear, compressed time. You can Link a
compressed table with other non-compressed tables or with waveform displays to
correlate the data to a linear view. This allows BOTH an efficient table view and a linear
'in-context' view.
The included '8051.dat' example demonstrates this well. The OE signal in that example is
spread across about 1.4 Million samples but can be displayed in less than 20 table lines
when compression is enabled. When this table is linked to a waveform view, scrolling
through this small table quickly scrolls the waveform to each significant event in the OE
signal. This is a real-world example captured from a real embedded system.
Down Sampled View (Zoom)
Another approach to making the table view useful in normal timing modes is to use
down-sampling. This mode presents the data in a time-linear format, but down-samples
the data to reduce information. Down-sampling preserves linearity but reduces
resolution. This is similar to turning down the sample rate while capturing data to extend
capture times at the expense of resolution. Of course the key difference is we are post
processing the data for the table view; not ignoring data during capture. In this mode, we
are simply displaying the data with less resolution to allow the user to see more
transitions while maintaining a linear time view. Since we have not changed the
underlying data itself, you can 'zoom in' (reduce down-sampling) at any time to see more
detail and actual timing. You can also link to other full-resolution tables or waveforms to
get a simultaneous view of the full detail and the data's correlation to other signals.
Delta vs. Linear time
Regardless of the display mode( normal, compressed or down-sampled), you can display
the time field in absolute or delta time. Absolute is the actual timestamp of the sample
(relative to trigger). DELTA mode shows the time between table lines. This is most useful
in compressed mode where it tells you the time between transitions. In normal and
down-sampled modes, it simply tells you the sample rate( since the time between each
line is constant).

List View Windows
List views present the decoded data of higher level signal types in column form. List windows can
be created after a signal that is supported by a list is created. To create a List view, select any of
the signals presented on the New List submenu of the Window menu. These signals can also be
presented in their raw data format using a Table view. (see: Table Views)

Using Link Groups
Link groups provide Synchronous Scrolling of a group of windows that display data. When
several windows are part of the same Link Group, each window will automatically update and
scroll when any member of the group changes its center time. The time reference and displayed
data of each member will "center" on the time the changing member centers on. This feature
keeps a group of windows synchronized to the same time in the captured data.
DigiView provides five link options that include Link Groups 1 through 4 and a "no-link" option for
windows that you want to keep independent.
Default link groups:
Link Group 1 this group.
Link Group 2 Link Group 3 Link Group 4 -
Waveform View 1 is always a member and all new windows initially belong to
Waveform View 2 is always a member of Link Group 2.
Empty Group, ready for members.
Empty Group, ready for members.
The link group of any window that displays data (such as Tables and Lists), can be changed
at any time. To change the group in these windows, Right-Click to access the menu of the
window, then choose the desired option from the submenu of the "Link" menu. The options on
this menu are displayed in the following Graphic.

All windows or views that can be assigned to a link group, will have a visible indicator with the
group number or an " * " (asterisk) displayed. The asterisk indicates an independent window
that is not linked to any group.

NOTE: When Waveform View 1 is "cross-linked" to Waveform View 2, all members of Link
Groups 1 and 2 will also be cross-linked. Waveform Views are cross-linked by using the Link

Searches
When analyzing the captured data, the ability to search forward and backward for specific pattern
matches or packet values, is indispensable. DigiView provides a general search type for pattern
matches, several search types for specific signal types (such as I2C) and a Search Manager to
quickly perform multiple searches and change criteria. The following sections provide details of
DigiView's searching capabilities.
•Defining Searches
•Performing a Search
•Using the Search Manager
•DigiView's Search Types
4.10.1 Define Searches
New searches are defined by clicking on the "Search->new" menu item and selecting the type of
search from the submenu. Multiple search types will be available depending on the type of
signals that have been defined. For example, if you have defined a signal of type "I2C", then the
I2C search type will be available from this menu. (For details on each search type, see: Search
Types). After selecting the type of search to define, a new search definition will be created (with
default properties) and its editor window will automatically open.
Searches are defined in terms of Signals matching specific criteria. Depending on the search
type, one or more signals are selected and a match pattern, match value or other conditions are
defined for each. Some search types even allow sequences of match conditions with the option
of placing the match marker at a specific point in the match sequence. When ALL specified

67
signals and conditions match the criteria, then we have a match.
All search types (and therefore all search editors) have the following common properties.
Search Name - Description
Use the Name field to describe the search. This descriptor will be displayed in the Search
Manager Windows and in the Global Search selection box.
From - Where to begin Searching
The 'search from' selection determines where the search starts from; the current center of
screen or the current marker location. Since the marker is placed at the center of the screen
after the first search match, these are often the same during consecutive searches. The main
difference occurs during the first search or between searches if you scroll the screen.
Set Marker - Mark the match point
The marker selection determines which marker is used to show the search match. You must
select one. Whenever the search matches, the selected marker is placed at the match point
and then centered in the searched window.
Delete Button - Deletes this search
Use the Delete button to dispose of the search and remove it from all search managers.
OK Button - Closes this search editor window
Use the OK button when you are finished making changes and want to close the editor for this
search.
Search Button - Performs this search
Use the Search button to test the settings you have just entered for this search. Right-Click to
search forward from the current time of the marker. Left-Click to search backward from the
current time of the marker. When you are satisfied with the search settings, you can close the
search and use any search button in the application to continue searching. (see: Searching)
4.10.2 Searching
Search Button
Left clicking on a search button searches back in time (previous match.) Right clicking on a
search button searches forward in time (next match.) See 'Define Searches' for details on

Invoking Searches
There are several methods of invoking a search. Each presents a slightly different way of
selecting the search and the target window, but they all perform the search in the same
manner.
If the search is configured to search 'from center time', then the search starts from the center
time of the FOCUSED window (possibly the last match). Otherwise the search starts from the
search's marker position (possibly the last match). In either case, the marker is positioned at
the location of the search match and then the FOCUSED window is centered on the marker. If
the window is part of a link group, then the entire link group is centered as well (see: Link
Groups). The center time of the FOCUSED window does not change if the search fails.
Regardless of how the search is invoked, we actually always run the DEFAULT search on the
FOCUSED windowed. We simply CHANGE the DEFAULT search or the FOCUSED window
before running the search in some cases. This creates a very consistent environment where
you can jump from one search button to another without surprises. The last invoked search is
always the current DEFAULT search and the last searched window is always the currently
FOCUSED window (until you do something to change it), regardless of how the search was
initiated.
Global Search
Beside the search selection box and search edit button is a SEARCH button. This search
button performs the Active Search, using the currently FOCUSED window as described without
changing either.
Local Search
Each Data Table, List and Waveform window has a local search button. When you click on a
window's local search button, that window becomes the FOCUSED window and then the
search is applied to it as usual (using this newly FOCUSED window). Clicking on a local
search button is the same as clicking anywhere on a waveform or table to FOCUS it and then
clicking on the Global Search button.
Search Manger Searches
When you click on a search button in the search manager, the DEFAULT search is changed to
that button's search and then the search is performed as usual (using this new DEFAULT
search). This has the same results as selecting the button's search from the Default search
selection pull-down and then clicking on the Global Search button. (see: Search Manager)
4.10.3 Search Manager Windows
The search manager window shows a list of all defined searches (see: Define Searches). It also
provides an easy method of executing or editing any of the searches. This is particularly useful if
you need to do a series of searches involving different search types.
To create a search manager, select "New Search Manager" from the Window menu. Multiple
search managers can be created.
Search - Each entry in the list includes a Search button in the left column. Left-click or Right-click
on the Search button to perform that search as described in the 'Searching' section.

69
Edit Search - Each entry in the list includes an Edit button in the second column. Click on the
Edit button to edit the parameters of a defined search.
Set as the Active Search - Click on the search name itself or use either of its buttons in the
search manager and the search will automatically become the Active (or Global) search. Any
search button in the program will perform the Active search.
4.10.4 Search Types
DigiView offers several types of searches to accommodate several types of signals. Depending
on the search type, one or more signals are selected and a match pattern, match value or other
conditions are defined for each. Some search types even allow sequences of match conditions
with the option of placing the match marker at a specific point in the match sequence.
When ALL specified signals and conditions match the search criteria, the time of the match
condition (or Match Point) will be centered in the window that has "focus". Any other windows that
are a member of the same Link Group, will also center on the match point. (see: Searching, Link
Groups)
Details of each search type below are explained in the following sections.
•Asynchronous Search
•I2C Search
•Pattern Search
•State Search
•Synchronous Search

DigiView User's Guide
4.10.4.1 Asynchronous Searches
The Asynchronous search type is only available if an Asynchronous signal type has been defined
(see: Defining Search Types, Asynchronous Signals).
This search type has a group of search terms (or criteria) that is specific to Asynchronous
signals, and can perform a search sequence by adding additional term groups. Groups can be
added by using the Copy or More buttons.
You can see in the ASYNC1 search displayed above, that it is configured for 2 sequential
searches. When the search button is selected, this search will walk through the signal's data until
it finds a sequence of packets with data that matches the values defined in the first term group
('<', 0x03, '>'). Then it will look at the very next packet (since the "skip count" is zero) to see if it
has an ERROR. If this packet does, then the focussed window will scroll to the match point and
set Marker X. If the next packet did not have an error, then the search starts over again from the
packet AFTER the one that contained the ASCII character '<'. This sequence of searching will
continue until a complete match is found or the end of data has been reached.
Skip: Determines whether to skip all packets until a match is found, or to skip the number of
packets specified in "Skip Count" and then see if the next packet is a match.

Navigating and Analyzing the Data
71
Skip Count: Determines the number of packets to skip before looking for a match. This value is
ignored if "Skip" is set to "Any number of packets".
Then Match: After skipping, this selection will determine the type of match to perform. Options
include specific packet errors, any packet error and simple data comparisons (<, >, ! =,=).
Value or Sequence: If searching for a comparison, you would enter the specific data or
sequence of data here. When using a sequence of data, each value must match the
comparison. For example if you specified "Greater Than" for the match, then specified "1, 2,
3" for the sequence. Then the first packet must be greater than 1, the second greater than 2
and the third greater than 3, before a match is declared. This value is ignored if searching for
any packet error.
A sequence of values must be delimited by a "," or a space (or both). Each value can be
specified as Decimal (0), HEX (0x00), binary (b00000000), ASCII ('0') or a mix of these
formats as shown in the first term group above (ASCII, HEX, ASCII).
Match Point: The selected marker will be set to the match point when a match occurs. If
multiple terms are used, then you can specify which term group should be used to mark the
match time. In the graphic above, the first group has been chosen as indicated by the blue
line to the left of the group. The line's color will reflect the color of the chosen marker when
selected. To select a different group, use the mouse to click on the line to the left of the group.
If no group is chosen, the first group will be the match point.
Disabled: Select this option to have the search ignore the term group.
Adding Term Groups: The "More" button is used to add term groups. Groups are added after
the selected group. If no term is selected, then the new term is added to the bottom of all term
groups. When a group is selected, it will be "highlighted" using the current theme's Window
Color. In the graphic above, the second group is selected.
Deleting Term Groups: The "Less" button is used to delete term groups. When deleting
groups, the selected group will be deleted. If no group is selected, then the last group will be
deleted. When a group is selected, it will be "highlighted" using the current theme's Window
Color. In the graphic above, the second group is selected.
Copying Term Groups: The "Copy" button is used to copy a term group. A copied group is
added after the selected group. If no term is selected, then nothing will be copied. When a
group is selected, it will be "highlighted" using the current theme's Window Color. In the
graphic above, the second group is selected.

4.10.4.2 I2C Searches
The I2C search type is only available if an I2C signal type has been defined (see: Defining
Search Types, I2C Signals).
This search type has criteria that is specific to I2C signals.
You can see in the I2C search displayed above, that it is configured to search for a specific 7 bit
Slave Address. When a 7 bit slave address is found it must first match the address condition
(equal to 0x0B). If this condition is not satisfied, the search continues to the next slave address
until a match is found. Once a match is found the next condition must be satisfied. If not, the
whole search begins again until all conditions match or the end of data is reached. When a
condition above is set to "any", the search will ignore that portion of a packet. For example if
Address is set to "any" then any 7 bit slave address is considered for the remaining conditions.
Packet Format: Select the packet type to search for. If "GCALL - Any General Call Address" is
selected, then the second selection box is activated for selecting a specific General Call or
"Any General Call".
Address: Select "Any" to ignore the address value, or select a comparison type (<, >, <>,=)

and enter the value for the comparison in the box below it.
Data: Select "Any" to ignore the data value(s) of this packet, or select a comparison type (=,<>,
contains, No Data) and enter the value or sequence of values for the comparison in the box
below it.
When using a sequence of data, each value must match the comparison in sequence. In the
example above, the packet must contain two consecutive values of 0xFF before a match is
declared. This pair can occur anywhere in the data, as long as the two values occur together,
in the order specified.
A sequence of values must be delimited by a "," or a space (or both). Each value can be
specified as Decimal (0), HEX (0x00), binary (b00000000), ASCII ('0') or a mix of these
formats.
Cycle: Select "Any" to ignore the cycle type, or select the type of cycle (Read or Write).
Status: Select "Any" to ignore the packet status or select the status to match. Status options
are NAK, Terminated, Error, Unknown. Each packet can only have one status value, so when
searching for a "Terminated" status, the search will not stop on packets with a "NAK", "Error"
or "Unknown" status.
Match Point: The selected marker will be set to the match point when a match occurs. The
match point is the starting time of the matching packet.

DigiView User's Guide
4.10.4.3 Pattern Searches
The Pattern search type is only available if a Boolean or Bus signal type has been defined (see:
Defining Search Types, Boolean Signals, Bus Signals).
This search type can be used to find a value of one signal or a pattern of values in multiple
signals, that lasts for a specified time period.
You can see in the "Fetch from 094D" search displayed above, that it will search for a pattern
consisting of values from three signals (ALE, PSEN, AD14-0) that lasts for a duration of more
than 50 nanoseconds. If this condition is found in the captured data, the specified marker will be
set to the time when the match occurs. In the above example, this would be 50ns after the
matching pattern begins.
Match Duration: Determines whether to skip all packets until a match is found, or to skip the
number of packets specified in "Skip Count" and then see if the next packet is a match.
Duration Units The duration qualifiers can be in ns,us,ms or sec and can use REAL numbers
(1.23 us).
Signals: Select a signal from this list to "add" them to the search. Signals added to the search
are displayed below the signal selection box where the pattern to match can be edited.
Match Pattern Format The match patterns can be specified in decimal, hex or binary. To
indicate a HEX specification, precede the number with '0x'. To indicate BINARY, precede the
number with 'b'. Binary specifications allow '0','1' and 'X' (don't care) characters. HEX
specifications allow HEX digits (0-1,A-F) or 'X' for a nibble of don't care bits. Decimal
specifications must use only 0-9.

4.10.4.4 State Searches
The State search type is only available if a State signal type has been defined (see: Defining
Search Types, State Signals).
This search type has a group of search terms (or criteria) that is specific to State signals, and can
perform a search sequence by adding additional term groups. Groups can be added by using the
Copy or More buttons.
You can see in the STATE search displayed above, that it is configured for 2 sequential
searches. When the search button is selected, this search will walk through the signal's data until
it finds the value defined in the first term group (0x9FD). Then it will look at the very next qualified
state change (since the "skip count" is zero) to see if it does not have a value that matches the
next term group (since the match condition is "Not Equal"). If it does not, then the focussed
window will scroll to the match point and set Marker X. If the next state did have the specified
value, then the search starts over again from the packet AFTER the one that contained the value
'0x9FD'. This sequence of searching will continue until all match conditions are true or the end of
data has been reached.
Skip: Determines whether to skip all packets until a match is found, or to skip the number of

packets specified in "Skip Count" and then see if the next packet is a match.
Skip Count: Determines the number of packets to skip before looking for a match. This value is
ignored if "Skip" is set to "Any number of packets".
Then Match: After skipping, this selection will determine the type of match to perform. Options
include simple data comparisons (<, >, ! =, =).
Value or Sequence: In this field, you would enter the specific data or sequence of data here.
When using a sequence of data, each value must match the comparison. For example if you
specified "Greater Than" for the match, then specified "1, 2, 3" for the sequence. Then the
first packet must be greater than 1, the second greater than 2 and the third greater than 3,
before a match is declared.
A sequence of values must be delimited by a "," or a space (or both). Each value can be
specified as Decimal (0), HEX (0x00), binary (b00000000), ASCII ('0') or a mix of these
formats.
Match Point: The selected marker will be set to the match point when a match occurs. If
multiple terms are used, then you can specify which term group should be used to mark the
match time. In the graphic above, the second group has been chosen as indicated by the blue
line to the left of the group. The line's color will reflect the color of the chosen marker when
selected. To select a different group, use the mouse to click on the line to the left of the group.
If no group is chosen, the first group will be the match point.
Disabled: Select this option to have the search ignore the term group.
Adding Term Groups: The "More" button is used to add term groups. Groups are added after
the selected group. If no term is selected, then the new term is added to the bottom of all term
groups. When a group is selected, it will be "highlighted" using the current theme's Window
Color. In the graphic above, the second group is selected.
Deleting Term Groups: The "Less" button is used to delete term groups. When deleting
groups, the selected group will be deleted. If no group is selected, then the last group will be
deleted. When a group is selected, it will be "highlighted" using the current theme's Window
Color. In the graphic above, the second group is selected.
Copying Term Groups: The "Copy" button is used to copy a term group. A copied group is
added after the selected group. If no term is selected, then nothing will be copied. When a
group is selected, it will be "highlighted" using the current theme's Window Color. In the
graphic above, the second group is selected.

4.10.4.5 Synchronous Searches
The Synchronous search type is only available if an Synchronous signal type has been defined
(see: Defining Search Types, Synchronous Signals).
This search type has a group of search terms (or criteria) that is specific to Synchronous signals,
and can perform a search sequence by adding additional term groups. Groups can be added by
using the Copy or More buttons.
You can see in the SSYNC 1 search displayed above, that it is configured for 2 sequential
searches. When the search button is selected, this search will walk through the signal's data until
it finds a sequence of packets with data that matches the values defined in the first term group
('p', '^', 0x1B, 0, 0x60, 1, 0x60). Then it will look at the very next packet (since the "skip count" is
zero) to see if it has a value greater than the value of the ASCII character 'v'. If this packet does,
then the focussed window will scroll to the match point and set Marker X. If the next packet value
was less than or equal to 'v', then the search starts over again from the packet AFTER the one
that contained the ASCII character 'p'. This sequence of searching will continue until a complete
match is found or the end of data has been reached.
Skip: Determines whether to skip all packets until a match is found, or to skip the number of

packets specified in "Skip Count" and then see if the next packet is a match.
Skip Count: Determines the number of packets to skip before looking for a match. This value is
ignored if "Skip" is set to "Any number of packets".
Then Match: After skipping, this selection will determine the type of match to perform. Options
include a Terminated Packet error and simple data comparisons (<, >, ! =,=).
Value or Sequence: If searching for a comparison, you would enter the specific data or
sequence of data here. When using a sequence of data, each value must match the
comparison. For example if you specified "Greater Than" for the match, then specified "1, 2,
3" for the sequence. Then the first packet must be greater than 1, the second greater than 2
and the third greater than 3, before a match is declared. This value is ignored if searching for
a packet error.
A sequence of values must be delimited by a "," or a space (or both). Each value can be
specified as Decimal (0), HEX (0x00), binary (b00000000), ASCII ('0') or a mix of these
formats as shown in the first term group above (ASCII, ASCII, HEX, DEC, HEX, DEC, HEX).
Match Point: The selected marker will be set to the match point when a match occurs. If
multiple terms are used, then you can specify which term group should be used to mark the
match time. In the graphic above, the second group has been chosen as indicated by the blue
line to the left of the group. The line's color will reflect the color of the chosen marker when
selected. To select a different group, use the mouse to click on the line to the left of the group.
If no group is chosen, the first group will be the match point.

Window Arrangement
DigiView makes extensive use of Docking and Tabbing to permit very flexible window
arrangements. All window settings, positions and sizes are saved along with the captured data
anytime you save a file or exit the program. These settings are all restored when you start the
software or load an existing '.DAT' file (see Saving and Restoring).
The main application is called the Primary window.
The windows created from the 'Windows' menu are called secondary windows.
Docking Windows
Tabbing Windows
5.1
Docking Windows
Dock Sites
The main application form has 4 docking sites; top,bottom, left and right. Any of the secondary
windows can be 'docked' to one of these sites by dragging the window over the site.
Docking a Window
When dragging a window over a docking site, a gray rectangle appears to indicate that the
dock site is willing to accept the window. Releasing the mouse button at this point docks the
window to the main form at this spot.
Multiple windows can be docked into each of the dock sites in a variety of positions. As you
drag additional windows over a given dock site, a different gray rectangle indicates where the
window would split into the dock site. You can drag it near the top, bottom, left or right edges
to control the placement.
If you drag the window inward a bit more, the rectangles change slightly to indicate a
willingness to split the space occupied by an existing docked window, rather than the dock site
itself. Dragging the window further towards the center of a docked window will cause the
rectangle to center in the window, which indicates the new window will "TAB" with the existing
window (see: Tabbing Windows). This flexibility allows you to dock the windows in virtually any
configuration.
Floating a window
To 'undock' a window, simply drag it off of the dock site by its title bar, double-click its title bar
or click on the down arrow in its upper right corner.
Over-riding Docking
If you wish to drag a window near a dock site but do not want it to actually dock, hold down the
control key while dragging. This will disable the docking behavior, allowing you to drop the
window without docking it.
(also see: Tabbing Windows).

Tabbing Windows
Tabbing windows
Secondary windows can be merged together by dragging one window over another. When you
drag any secondary window over another secondary window, a centered gray rectangle
appears.
This indicates that dropping the window at this point will merge them together into a single
window. Each original window appears on a TAB in the new window. Dropping additional
windows onto the tabbed window creates additional tabs.
© 2007 TechTools
82
DigiView User's Guide
Tabbed windows can be docked just like any normal window. Also, a secondary window can
be tabbed with a secondary window that has already been docked. Simply drag the window
over the center of the docked window until you see the centered gray rectangle. This will TAB
them together at the docked location rather than dock the new window next to the existing
window.
Floating a tabbed window
You float a tabbed window just like a normal secondary window; simply drag it off of the dock
site using its title bar, double-click its title bar or click on the down arrow in its upper right
corner. This will float the entire tabbed window, keeping all of its tabs intact.
De-Tabbing a window
To remove a window from a tab, simple grab the tab and drag it or double-click on the tab. This
extracts the window from the tabs and floats it. When only two windows are tabbed together
and one of these is removed, the tabbed window will be disposed of and the remaining window
will now occupy the position previously occupied by the tabbed window. If the tabbed window
had been docked, then the remaining window is now docked in its place. See Docking
Windows for more information on docking.
Tab Window Options
After "Tabbing" windows together, several display options are available from a pop-up menu
that is accessible by Right-Clicking on any of the Tabs. For details on these options, see Tab
Window Options.
(also see: Docking Windows , Tab Window Options).
5.2.1
Tab Window Options
After "Tabbing" windows together, several display options are available from a pop-up menu that
is accessible by Right-Clicking on any of the Tabs. Available options depend on the selected Tab
Orientation.

83
Tab Orientation
Options are TOP, LEFT, BOTTOM, RIGHT. Choose one of these options to change the
placement of the Tabs in a tabbed window.
Tab Rows
Options are SINGLE, MULTIPLE. Choose multiple to have the tabs align in a single row
with "scroll buttons" on the right. Choosing multiple will change the tabs to the default
multiple row behavior and remove the "scroll buttons". Tab orientation must be set to Top
or Bottom to select the Single option.

DigiView User's Guide
Exporting
The captured data can be exported to a file in ASCII format for further analysis or documenting
purposes. DigiView provides three export methods to chose from with each method having a few
unique features. These features are documented in the next three sections:
•Exporting All Signal Data
•Exporting From List Windows
•Exporting From Table Windows
Properties common to all three export methods are discussed below.
Export To
At the top of each export dialog, the file name and path for the export file will be displayed. To
change the name or location, chose the button to the right of the filename. You can chose any
valid storage device for your system including a Network Drive, Floppy Disk, FLASH Memory,
and etc.
Time Range
Select the Starting time and Ending time of the data to export. You can select from several
predefined time points (i.e. Waveform View 1 Start, Trigger, Marker X, etc) or select Custom to
manually enter the time.
Estimated Free Disk Space
The available space of the export destination is calculated and displayed here. The available
space will be calculated whenever the destination changes. While the export is in progress, this
will be updated to keep you informed of remaining space. If the available space becomes too
small for the remaining portion of the export, then the export will automatically finish without
exporting the rest of the data.
Required Disk Space
The amount of disk space required to hold the exported data will be displayed here. Since all
storage devices require a minimum amount of space to hold a file, the minimum file size will be
shown if the exported data is smaller. If the export size is very large, the background color of
this display will turn to yellow. If the export size exceeds the available space on the storage
device, the background color will turn to red and the export prevented from being performed.
The export size will be calculated whenever any option or the destination changes.

Exporting
87
Progress indicator
The lower left portion of the Export dialog will display the progress of the export. The progress
display will indicate the number of bytes already exported, the percentage of the data already
exported and the number of bytes per second being written to the storage device.
Abort Button
The export can be canceled at any time by selecting the Abort button. All data exported up to
the point of cancellation will be available in the exported file.
Close Button
To exit the Export window, chose this button. If an export is in progress, the export will be
canceled automatically.
Export Button
After selecting the desired export options, chose this button to begin the export. This button will
be disabled while an export is in progress or the export size is being calculated.
6.1
Exporting All Signal Data
This export method can be selected from the File menu and provides a means of exporting the raw
data of all defined signals. The available options let you chose which signals to export, time format,
numerical format, field separator, inclusion of line numbers, inclusion of a timestamp and whether to
use compression. (see: Exporting)
The Exported Data Example area will be updated automatically to reflect any changes in export
options.
© 2007 TechTools
88
DigiView User's Guide
Timestamp
If the "Include Time Stamp" option is selected, the time field will be formatted as the absolute
time or (if set to Delta) as the time since the previous sample (or the last known sample after
the starting time). If the "Data Compression" option is set to OFF and this option is set to Delta,
then the time field will show the sample rate.
Numerical Format
This option determines the formatting for each signal that uses more than one channel (Boolean
signals will always be formatted as a '1' or '0'). This option will display the format setting of a
signal when a signal is selected. To change the format for a signal, first select the signal in the
Signal Selection area. If changes are allowed for the selected signal, then the format options will
"enable". Select the desired option.
Field Separator
Chose the character for separating each item on a line of exported data.
Include Line Numbers
Select this option to include a consecutive line number at the beginning of each line.
Include Time Stamp
Select this option to include the time of each exported sample.
Signal Selection
Check each signal to include in the export. The order of export is determined by the order in
which each signal is checked. To have the export order match the listed order, use the Clear All
button to clear all selections, then use the Select All button to select all the signals in the order
shown. To move a signal to the end of the export line, uncheck and then recheck the signal.
When a signal is highlighted with the mouse, its export format setting will be shown in the

Numerical Format option. This option can be changed by selecting the desired format
(excluding Boolean signals).
Data Compression
Setting this option to ON will greatly reduce the size of the export file. With compression on, the
redundant or "dead" periods of data will be excluded and only changes in the data will be
exported. If this option is set to OFF, then no data will be eliminated and all samples at the
maximum resolution will be exported. This could lead to very long exports with sizes up in the
Terabyte range.
Clear All Button
Use this button to "uncheck" all signals in the Signal Selection Area. Unchecked signals will be
excluded from the export.
Select All Button
Use this button to "check" all signals in the Signal Selection Area. All checked signals will be
included in the export.
Exported Data Example
This area provides an instant "preview" of the data to export and is updated when any option or
signal selection is changed.
6.2
Exporting from List Windows
This export method can be selected from the File menu or directly from a List Window's menu. List
Exports export the decoded data of higher level signals (such as I2C), and will have a slightly
different set of options that are specific to each signal type. (see: Exporting, Signal Types, List View
Windows)
The Exported Data Example area will be updated automatically to reflect any changes in export
options.

6.3
Exporting from Table Windows
This export method can be selected from the File menu or directly from a Table Window's menu.
Table Exports provide all the same options as the "Export All" function, but will automatically include
all columns of the table. This means you will not have to select which signals to export, plus all
channels of any signals that are "expanded" will also be included in the export. This is the only
export method that will export expanded channels. (see: Exporting, Export All, Table Windows)
Tables display and export signals in their "raw" data format. If you need to export the decoded data
of higher level signals (such as I2C), then the List Export should be used instead. (see: List Export,
I2C Signals)
The Exported Data Example area will be updated automatically to reflect any changes in export
options.

Creating, Saving and Restoring Files
Save As
The Save As function is under the FILE menu. The current state (Zoom, time, cursor locations,
waveforms associations…), waveform definitions, trigger definitions and the entire data buffer
are saved to the file you select. The data is always stored in compressed format, so its
size will vary from a few KBytes up to just over 4 MBytes.
Open
The Restore function is under the File menu (File->Open). This will load a previously saved
data file along with all of its settings.
Auto Save/Restore
The "Auto Save" and "Auto Restore" options are found in the Environment settings (found under
the CONFIG menu). When both of these options are enabled, DigiView auto-saves the current
data, settings and state when you exit the program (or load a new file) and auto-loads this
information when you start the program. This allows you to pick-up where you left-off the next
time you start the software without having to save/restore. You can still save the file manually
anytime you need a specific snap-shot of the data by using the "Save As" option or "Save"
button.
New
To start completely fresh and eliminate all defined signals, searches, data, triggers and
windows, select the New option from the File menu. For additional ways of starting a new
session with some pre-defined windows, see: Using Templates.
When creating a new Capture file, you must select the proper analyzer model and optionally the
preferred sampling mode. For this reason, the software will provide a selection window with
information regarding any detected hardware as shown below. Simply select the Model and the
Sampling Mode, then click on the "OK" button to create a new file. If you do not want to create a
new file, then select cancel to continue with the currently loaded file.

Using Templates
You may have spent some time Docking, Tabbing and resizing windows to achieve a comfortable
window arrangement. To re-use the arrangement for a new session without starting with existing
signals, searches, data and so forth, you can save the arrangement as a Template. (also see
Saving and Restoring).
Save As Template
The Save As Template function is under the FILE menu. All window settings, positions, Dock
sites and sizes are saved to a Template File (*.DVT) and all data, signals, searches, markers
and trigger settings will be ignored.
New From Template
The New from Template function is under the File menu. This will load a previously saved
Template File (*.DVT) to start a new session with some default window and docking
arrangements.

DigiView Compression
There is no need to understand DigiView's compression to use it. This is just here for the
curious (or skeptical).
We want two conflicting features in a logic analyzer; high sample RATES (high resolution) and
high sample COUNTs (a lot of data/time). We usually reduce sampling RATES to capture more
data because sample COUNTs (data buffer depth) is fixed. To combat this trade-off, the sample
buffer is made as deep as possible. However, this approach is linear and does not scale well.
Doubling the buffer doubles either TIME or sample RESOLUTION. It can take gigabytes of
memory to achieve both if your data transitions are fairly sparse (microsecond or more gaps).
Ideally, we would like to have high sample RATES AND high sample COUNTs to capture a long
time-span with high resolution.
DigiView achieves this, like other logic analyzers, by using a deep data buffer. However, DigiView
also attacks this problem from another, even more effective angle. DigiView uses one or more
real-time, hardware based compression techniques to compact the captured data. This has a
much greater impact than increasing the buffer depth.
The data captured in logic analyzer applications is often stable for multiple sample periods
(particularly at higher sample rates). This, coupled with fast sample times and a very long
run-length limit, makes our compression very applicable in real-world applications.
To illustrate the effect of DigiView's compression and also present it in a manner that is more
relevant to real-world usage, we have calculated several typical performance benchmarks for
each DigiView Model and sampling mode. You may actually see better performance ratings than
the conservative estimations below.
DV1-100

DigiView User's Guide
DV3400 - 200MHz
DV3400 - 400MHz
Final note: the data is compressed in real-time with dedicated hardware and is NEVER fully
de-compressed (which could result in data files much larger the available hard-drive capacities).
DigiView software transfers the entire compressed data buffer from the hardware to internal PC
memory in compressed form. This allows us to transfer the entire buffer in about 1 second. The
waveform display routines fetch only enough data from the compressed buffer to fill the viewable
portion of the display screen and even that is compressed.
