In the tran command (tran 10m 10 1) you asked it to strobe at 1 second intervals. So, no matter what the signal, you get samples 1 second apart. If you add "trace all" to the tran command you will see all of the samples, which should produce a smoother waveform. How it works is a throwback to when people actually looked at ASCII plots. It needs to change to make "trace all" the default, and have the strobe interval require a keyword "strobe" like spectre does. The actual time stepping is determined internally. There will be extra steps internally if needed to get a proper simulation, but they are not displayed unless you ask for them. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
