Hi,

CodeWarrior comes with a built-in trace viewer and support for hardware trace while something like this is not present in KDS.

I recommend you check if gcov can help. see Erich's article:

Code Coverage with gcov, launchpad tools and Eclipse Kinetis Design Studio V3.0.0 | MCU on Eclipse

can this help you?

Have a great day,
Zhang Jun

For runtime (time spent) you can have a look at using gprof:
