Abstract
The present invention discloses a digital integrated circuit simulation method and simulator. The method comprises: obtaining a circuit diagram of the digital integrated circuit and a checkpoint in the circuit diagram; determining a point relevant to a boundary between a two-value simulation and a multi-value simulation in the circuit diagram and a state of the relevant point according to the checkpoint; determining a boundary position, as well as a boundary type of the boundary position, of the boundary between the two-value simulation and the multi-value simulation in the circuit diagram according to the relevant point and the state of the relevant point; inserting a conversion circuit at the boundary position according to the boundary type of the boundary position; and modeling and simulating the circuit diagram into which the conversion circuit is inserted. The method and simulator can reduce simulation time and the needed storage resources.
