I want to do a DC sweep (.DC):

-3.6V to -1V (step size = 2.6V)

-1V to +2V (step size = (100/3)mV)

+2V to +7.2V (step size = 5.2V)

(Lots of data points around the "knee" :-)

That makes a list that PSpice barfs on, claiming "list too long".

Anyone know some gimmicks to get around that limitation?


use two voltage sources that add to give the desired effect in series?


The problem was the need for different step sizes in different
regions. Reason: Feeding data to another application that can handle
only 100 total data points.
