Making Software Performance Measurements
To set up the trace command for duration measurements
Or:
trace after module_name start or module_name end
only module_name start or module_name end
counting time
Where "symbol_entry" and "symbol_exit" are symbols from the user program.
Or, where "module_name" is the name of a C function or Pascal procedure
(and is listed as a procedure symbol in the global symbol display).
Examples
To specify a trace display depth of 512:
display trace depth 512
To set up the trace command for duration measurements on the
interrupt_sim function:
trace after interrupt_sim start or interrupt_sim
end only interrupt_sim start or interrupt_sim end
counting time
The trace specification sets up the analyzer to capture only the states that
contain the start address of the interrupt_sim function or the end address of
the interrupt_sim function. Since the trigger state is also stored, the analyzer
is set up to trigger on the entry or exit address of the interrupt_sim function.
With these states in memory, the analyzer will derive two measurements:
time from start to end of interrupt_sim, and time from end to start of
interrupt_sim.
