Restoring the Current Measurement
The performance_measurement_initialize restore command allows you to
restore old performance measurement data from the perf.out file in the current
directory.
If you have not exited and reentered emulation, you can add traces to a performance
measurement simply by entering another performance_measurement_run
command. However, if you exit and reenter the emulation system, you must enter
the performance_measurement _initialize restore command before you can add
traces to a performance measurement. When you restore a performance
measurement, make sure your current trace command is identical to the command
used with the restored measurement.
The restore option checks the emulator software version and will only work if the
perf.out files you are restoring were made with the same software version as is
presently running in the emulator. If you ran tests using a former software version
and saved perf.out files, then updated your software to a new version number, you
will not be able to restore old perf.out measurement files.
Examples To initialize the duration measurement:
performance_measurement_initialize duration <RETURN>
