METHOD AND DEVICE FOR SIMULATING A CIRCUIT DESIGN

摘要

The present invention discloses a method and device for simulating a circuit design. The method includes identifying at least one Sequential-cell-To-Sequential-cell (S2S) block in the circuit design, wherein the S2S block includes at least one input sequential cell, at least one output sequential cell, and an intermediate portion between the input sequential cell and the output sequential cell, wherein the intermediate portion includes at least one combinational cell; determining logic characteristics and timing characteristics of the intermediate portion; and replacing the intermediate portion with a functional module having the logic characteristics and the timing characteristics to generate a simplified circuit design to be used in simulation. With the technical solution according to embodiments of the invention, time needed in simulation is shortened.
