9.3.5. Changing the default format of time information

To change the default format in which time information is displayed in the Analysis window:

  1. Select Scale Time Units... from the View menu to display the List Selection dialog box.

  2. Select one of the following time formats:

    • Default

    • Picoseconds

    • Nanoseconds

    • Microseconds

    • Milliseconds

    • Seconds

    • Cycles.

  3. Click OK.

Considerations when changing the default time format

The default format depends on both your TPA and your target processor. ETM-enabled processors have a default time format of nanoseconds. ETMv3 targets default to:

  • Cycles if cycle accurate tracing is enabled

  • Picoseconds if timestamping is enabled.

If cycle accurate tracing and timestamping are both disabled for ETMv3 targets, then setting the default format to Default provides instruction count information.

You must define the processor speed for scaling in the following cases:

  • When the default format of the target is cycles and you select any other format.

  • When the default format of the target is not cycles and you select Cycles as the display format.
