Sounds like you need to examine closely when you are
asserting AccLoad--whether or not it is a function of
the present/next state, and if it is not, ask, "Should it be?"
Also, do you assert AccLoad if you are doing a store,
and will the delay through your ALU be slow enough to
allow you to do so, or should you modify (again) when
you assert AccLoad?

I had the same problem, sans the PC incrementing beyond
the next instruction before the IR latches it. You will
want to examine your IRLoad signal for that.
