PERFORMANCE OF CIRCUIT SIMULATION WITH MULTIPLE COMBINATIONS OF INPUT STIMULI

This invention provides techniques and tools for reducing circuit simulation time when an electronic circuit with multiple input vectors is simulated. Instead of running the simulation for each input vector one at a time, the circuit-simulation application runs the simulation of the circuit for all input vectors simultaneously. Efficiencies in the simulation are obtained during each iteration of a transient analysis by grouping circuit instances with different input vectors based on a predetermined criteria, and producing a combined solution for circuit instances within each group.
