To define a prestore qualifier
• Place your prestore qualification into the entry buffer. Then choose
Trace→Only() Prestore.
• Using the command line, enter commands as follows:
•
trace prestore <bus_state>
•
trace prestore anything
You use the prestore qualifier to save states that are related to other routines that
you're tracing. For example, you might be tracing a subprogram, and want to see
which program called it. You can specify calls be prestored and that entries to the
subprogram be stored. The easiest way to do this is to prestore program reads that
