CHAPTER2 Dependence Functions
2.1.10 Trace
The address and status information can be sampled during program execution to record
it in a trace buffer. This function is called a trace.
■Trace
Data recorded with the trace function can be used to make a detailed analysis of a program execution
history.
The trace buffer is in the form of a ring. When it becomes full, it records the next data by automatically
overwriting the buffered data at the beginning.
• Trace Sampling
• Setting trace
• Displaying trace data
• Display format of trace data
• Searching trace data
• Saving trace data
• Clearing trace data
■Trace Data
The simulator debugger can sample 1000 frames of trace data. Trace data sampling occurs at the address of
the executed instruction.
