Saving and Restoring Trace Data and
Specifications
The emulator/analyzer can save your trace data and trace specifications in a
file for later use. This can help you record measurement results that you can
use for comparison with other tests, and it is useful to automate
measurements.
Suppose you're using the emulator in a manufacturing test application. The
target system is your product board. You might build a command file that
recalls a trace specification, makes the trace on the target board, and then
recalls a previous measurement result (from a working product) and
compares it to the new measurement (using the UNIX diff command).
This section describes how to:
•
Store a trace specification.
•
Store trace data.
•
Load a trace specification.
•
Load trace data.
To store a trace specification
•
Choose File→Store→Trace Spec... In the dialog box, select an
existing filename or specify a new filename to contain the present
trace specification. Then click OK.
•
Using the command line, store the current trace specification by
entering:
store trace_spec <filename>
<filename> is any UNIX file name including paths. The extension .TS is
automatically added to the file name.
The trace specification file is a binary file.
The store trace_spec command allows you to save a trace specification
(effectively the current trace command with all trigger, storage and sequence
options) in a file for later use. For example, you might have several trace
