About STVD7 debugging features
A number of advanced features are included in the STVD7 software:
• Data Breakpoints on the occurrence of a memory access via a read operation or a write operation, or both.
• Instruction Breakpoints on the occurrence of an opcode fetch.
• A Logical Analyser that allows you to control either the recording of the trace buffer, or a break in the execution of the application using a series of specific conditions (events).
• A Trace window to view the contents of the trace buffer, which permanently records in real time on 32-bits:
Address and data bus information.
Flag status and 4 external signal values.
You can record up to 1024 executed cycles. Using trace filtering, you can filter out only those cycles you wish to record in the trace buffer. You can equally control which of the recorded cycles are displayed in the Trace window using line filtering. Addresses, data, control/status bits and 4 user signals are displayed using mnemonic and user symbols.
• Internal synchronization signals can be output to either of two Trigger Outlets on the front panel of the emulator (OUT1 or OUT2). This feature enables you to count events using an external equipment, when optimizing software for example, or to synchronize an oscilloscope when debugging hardware.
• Hardware Events can be used to control the sending of signals to the trigger outputs.
• You can choose the output that you wish the signal to be sent to (i.e. either
OUT1 or OUT2).
• A Hardware Test function that allows you to perform a number of hardware tests on the Development Board, at your choosing. Refer to
Running the
Hardware Test for more information.
• A powerful online help facility can be invoked at any time to give additional information about the commands, the processor or the emulator kit.
