I disagree.  Clearly a logic model will do cycle accurate simulation.  So an 
abstraction of that which still preserves the details of out of order 
execution, data dependency, etc., will also be cycle accurate.

It certainly is true that modern high performance processors with all those 
complexities are hard to simulate, but not impossible.
