8-28 Timing: Using the Analyzer
The Timing Analyzer Softkey Interface allows you to store trace
memory measurements in a file and then compare the stored data
to a subsequent trace measurement.
In order to properly compare a saved trace measurement, its data is
stored with all the specification (configuration) information. A
configuration save file that is saved with the data can then be
referred to as a "compare file".
The command
configuration save_in COMPARE with_data
write_protect
creates a file "COMPARE.TR" that contains specification
information along with the current trace memory data. The file is
write protected so that you cannot write to the file with a
subsequent "configuration save_in" command.
In order to compare current trace data with previously stored trace
data, you must first select a compare file.
File
The command
compare file_is COMPARE
from the post processing specification screen will select the
previously generated "COMPARE.TR" as the current compare file.
You can also enter
post compare file_is COMPARE
from any screen to select "COMPARE.TR".
