Well, I didn't get any "time axis error" when running a .tran using ngspice. One thing: you don't need a "gnd 0 0" card in there.
Anyway, here is a very simply SPICE deck which runs under ngspice & outputs a pretty .tran waveform when you do a "plot Vout": LAB1 RF CIRCUIT Vtest 2 0 PWL(0ns 0V 100us 0V 101us 1V 2ms 1V 2.0001ms 0V) * VAC 2 0 DC 0 AC 1 * gnd 0 0 -- You don't need this at all C1 Vout 0 10nf R1 2 Vout 50K * R1*C1 time constant = 5e-4 sec = 0.5ms * .AC LIN 10 1K 1MEG .tran 10us 5ms .END Try playing with this. Don't forget to say "run" after you read it in. Stuart > > Using ngspice or tclspice. > > I seem to have a handle on using spice but when I try to do this I get a > time axis error.
