  • Mechanism for recognizing and abstracting pre-charged latches and flip-flops
    Patent number: 6848090
    Abstract: An abstraction mechanism is disclosed, which is capable of recognizing and abstracting precharged latches and flip-flops, and which is capable of generating a cycle ready representation of the precharged latches and flip-flops. In one embodiment, the abstraction mechanism abstracts precharged latches and flip-flops by using cofactors. In doing so, the abstraction mechanism accesses a logic level representation of a structure. Based upon the logic level representation, the abstraction mechanism derives one or more cofactors. These cofactors are then tested to determine whether they indicate precharge behavior, and whether they indicate latch or flip-flop behavior. If the cofactors indicate both precharge behavior and latch or flip-flop behavior, then the abstraction mechanism abstracts the structure as a precharged latch, or a precharged flip-flop, whichever is appropriate.
