초록
Logic simulation is playing a very important role for design verification as circuits are larger and more complicated. However unknown values in 3 value simulators may generate the X-propagation problem which makes inaccurate output values. In this paper, a new partitioning method and a new simulation algorithm are developed to deal with the X-propagation problem efficiently. The new algorithm can optimize simulation time and accuracy by controlling partition depth. Benchmark results prove the effectiveness of the new simulation algorithm.
