Qualifying Trigger And Store Conditions - HP 64746 User Manual

Qualifying Trigger and Store Conditions

This section describes tasks relating to the qualification of trigger and storage states.
You can trigger on, or store, specific states or specific values on a set of trace
signals (which are identified by trace labels).
Also, you can prestore states. The prestore qualifier is a second storage qualifier
used for storing states that occur before the normally stored states. Prestore is
useful for capturing entry points to procedures or for identifying where global
variables are accessed from.
This section describes how to:
•
Qualify the trigger state and the trigger position in the trace.
•
Trigger on a number of occurrences of some state.
•
Qualify states stored in the trace.
•
Prestore states before qualified store states.
•
Change the count qualifier.
•
Trace until the analyzer is halted.
•
Cause the emulator to break into the monitor when the analyzer triggers.
Expressions in Trace Commands
When modifying the analysis specification, you can enter expressions which consist
of values, symbols, and operators.
