A circuit simulator based on the waveform-relaxation method using selective overlapped partition and classified latencies

Several techniques for improving simulation costs in the waveform relaxation method are discussed. In the circuit partitioner field, selective overlapped partition and duplication depth ideas are proposed. For the circuit simulation part, several modifications to the conventional simulator are demonstrated and classified latencies proposed. Experimental simulations are compared with results obtained from SPICE2. The results indicate conclusively that, if the circuit size is over one thousand, SUPER-SPICE is more cost-effective than SPICE2.<
