Hmm, I just checked through some sample Spice netlist code I wrote a while back.. And the equations I seem to be using there are as follows: .subckt inv a y N=4 P=8 M1 y a gnd gnd NMOS W='N' L=2 AS='N*5' PS='2*N+10' AD='N*5' PD='2*N +10' M2 y a vdd vdd PMOS W='P' L=2 AS='P*5' PS='2*P+10' AD='P*5' PD='2*P +10' .ends See if these equations match up with the results given by Electric (from brief inspection they don't seem to). I will have to rethink where i came up with these equations. -- You received this message because you are subscribed to the Google Groups "Electric VLSI Editor" group.
