Could some SPICE guru please help ? I use HSPICE and Ngspice, both text input based. I wish to measure differential current output from a test circuit. For each output node, I can add a zero voltage output voltage source as for example VTST 3 4 DC 0.0 AC 0.0 And then measure the current at each output node as .TRAN PRINT I(VTST1) ; and so on But how do I combine the output from these two zero voltage voltage sources to get the actual differential current ? Any hints, suggestions would be of immense help. Thanks in advance.
