The last processor I successfully modeled was the old 6502 (Apple II), since
then processor behavior has become too difficult to sort out in any
reliable way (IMHO).

It would be interesting for the OP to reveal what kind of processor is
involved, and how complex. I am going to assume it doesn't support
interrupts or threads, otherwise there is little chance to mimic its
behavior.
