When netlisting fails or the simulation
does not start
If you have problems starting the simulation, there may be
problems with the design or with system resources. If
there are problems with the design, PSpice displays errors
and warnings in the Simulation Output window. You can
use the Simulation Output window to get more
information quickly about the specific problem.
To get online information about an error or warning shown in the
Simulation Output window
