place a spice directive on the schematic (Key "S")
like
".dc v1 2.0 10.0 0.01"
for a DC sweep

or

".ac dec 100 0.01 10meg"
for an AC sweep.

For more details look into the help menue.

The _single_ source for AC stimulus must have the voltage field
set to "AC 1." (be sure to enter the blank between AC and 1 ...)

Only one sweep type can be active for a simulation. So
SWCAD comments out the unactive directive with a ";" before it.

When you start the simulation you will automatically invoke
the window with the plots. Do a right click to the plot to select
special traces, or make a left click on the axes to set up
min, max and increment.
Re-name signals with the "Label Net" command.
Identify/plot single signals by placing the cursor over the
signal in the schematic.

BTW: If you re-name a signal or component never ever try to enter
a name that has blanks - else you will get unexpected and misleading
error messages.

HTH.

Regards,

Joerg
