Hello
You should be able to see cycle counts in the CodeWarrior debugger if you use the Trace component instead of the Softtrace one.
There is one limitation in V5.1. The simulator starts counting the cycles when application is started.
You cannot reset the cycle count to 0 at a given time to evaluate cycle count for a specific portion of code.
If you upgrade to CodeWarrior for MCU V6.0, you have to ability to reset the cycle count if you wish.
