Stopwatch
You can open the Stopwatch from Window ▸ Debugging ▸ Stopwatch. If you have set breakpoints in your code, the stopwatch does give you the cycle count from one breakpoint to the other. But the count is not cumulative, in that it always starts from zero after halting at a breakpoint. However, please note the Stopwatch feature is not fully implemented in the IDE as of now. It should be completely supported in the future.
