The graph dialog box has a Sweep textbox where you can write the
X-axis variable. By default xschem uses the first variable in the raw file for the X-axis, and this is the
sweep variable the simulation was done, so time for transients, frequency for AC sims, voltage or current sweep
- for DC sims. Example below shows a cmos latch where a DC simulation has vbeen done sweeping the voltage generator
+ for DC sims. Example below shows a cmos latch where a DC simulation has been done sweeping the voltage generator
on the a input from 0 to 3V.
If v(a) v(z) is specified in the Sweep textbox (or a z) the z signal
