Chapter 7 Setting up analyses and starting simulation

5 Set up any other analyses you want to perform for the
circuit by selecting any of the remaining analysis types
and options, then complete their setup dialog boxes.
Execution order for standard analyses
For normal simulations that are run from a simulation
profile, or in batch mode, only the particular analysis type
that is specified will be executed.
During simulation of a circuit file, the analysis types are
performed in the order shown in Table 3
. Each type of
analysis is conducted only once per run.
Several of the analyses (small-signal transfer, DC
sensitivity, and frequency response) depend upon the bias
point calculation. Because so many analyses use the bias
point, PSpice calculates this automatically. PSpice’s bias
point calculation computes initial states of analog
components.
