US Patent 7260515 Method and apparatus for simulating transparent latches

A method and apparatus for cycle-based simulation of a transparent latch includes classifying a phase of the transparent latch, classifying a phase of an input to the transparent latch, and classifying a phase of a simulation cycle. The transparent latch is simulated as a cycle-based simulation element based on the phase of the transparent latch, the phase of the input to the transparent latch, and the phase of the simulation cycle.
