Would it be much effort to implement a simplified version, i.e. ignoring pipelining, just counting a fixed number of cycles per instruction?
Is it not just a case of ensuring that calls to tick() with appropriate argument value are implemented in the right places? Specifically, all the inst_*() functions in inst.cc.
Unless I am being naive, I think the only difficulty would be with what to do for DIV/DIVW, which take a variable number of cycles that depends on their operands. Also, special attention would need to be paid to the cases where instructions are utilising indirect addressing (e.g. "ld a, [0x1234]"), which typically take an extra 3 cycles compared to the common case.
