    摘要： Method and apparatus for circuit simulation, comprising: partitioning circuit into a first simulation circuit and a second simulation circuit; generating equivalent circuit of first simulation circuit at present simulation time-point based on port current/port voltage of simulation time-points prior to present simulation time-point, a pre-obtained port voltage of the first simulation circuit under port open-circuit condition/port current of the first simulation circuit under port short-circuit condition, and a pre-obtained impulse-response of the first simulation circuit; simulating circuit consisting of the equivalent circuit and the second simulation circuit based on a preset algorithm to obtain unknowns in the second simulation circuit; and obtaining unknowns in the first simulation circuit based on port current/port voltage. Comparing with prior art, this invention reduces circuit scale by equivalencing linear portion of circuit, namely, the first simulation circuit. Thereby computation amount in simulation process is reduced to meet requirements for real-time simulation.
