• In the Analysis Setup dialog box, click the Temperature
button. Specify the temperature or list of temperatures in the
Temperature Analysis dialog box.
• If needed, in the Analysis Setup dialog box, select ( ✓) the
Temperature check box to enable it.
• Start the simulation as described in Starting Simulation on

When a temperature analysis is run, PSpice A/D reruns standard
analyses enabled in the Analysis Setup dialog box at different
temperatures.
Temperature analysis allows zero or more temperatures to be
specified. If no temperature is specified, the circuit is run at
27°C. If more than one temperature is listed, the effect is the
same as running the simulation several times, once for each
temperature in the list.
Setting the temperature to a value other than the default results
in recalculating the values of temperature-dependent devices. In
example.sch (see Figure 12-7), the temperature for all of the
analyses is set to 35°C. The values for resistors RC1 and RC2
