Logging Statistics

You can log the detail from each sample to a file for subsequent
review. The "statistics"' command in the post processing
specification allows you to specify a file name to write the
information. For logging to occur, one of the statistical analysis
calculation options must have been previously chosen.
The commands
display timing_diagram
indicate time_interval_x_o
mean_and_standard_deviation
post statistics log_to_file STATISTICS
<RETURN>
post halt_repetitive_execution
when_runs_equal 8 <RETURN>
execute repetitively <RETURN>
start a eight run statistical trace. After execution halts, enter the
command
post statistics log_to_file none
to disable statistics logging. The generated output logs will look
like:
