In ucSim, where or what defines how many simulated cycles each instruction takes? Specifically, I am looking at the STM8 simulator.
Nowhere, and nothing defines that. Correct tick counting is not implemented in uCsim (except s51). It counts 1 clock (tick) for every instruction which will be unreal especially when lot of jumps happen.
To compare quality of two programs, I recommend to use vclk instead (available in sim_vclk variable), it will be sum of the FETCH, READ, and WRITE operations.
