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 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 256 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.
• Hardware Events can be used to control the trace recording or the sending of
signals to the trigger outputs.
• A powerful online help facility can be invoked at any time to give additional
information about the commands, the processor or the emulator kit.
