Hi,
If you care for large large signal stata, you possibly FDD2P(Frequency-Domain Defined Devices) or SDD2P(Symbolically Defined Devices, 2Ports), but i have not use SDD2P to simulate, pl try. If you make good winning, pl tell me.
note
1. make formula V[i, j](FDD2P) or I[i,0] (SDD2P) of Pin VS. Pout by mathcad software.
