Cadence ELC Biphase Flip Flop Characterization

eklikeroomys

 Has anybody ever characterized biphase flip flops using ELC before? Im having problems with floating registers, as ELC asserts the second clock before the first, the second register takes the value from the first register (which is floating), and thereby yields a random output, causing the smulation to fail.

     Never mind, it had nothing to do with the biphase flip flops. Seems like ELC wants nothing to do with hierarchical cells, eventhough they are expanded.
