Temperature Analysis
DR. SPICE allows you to set temperature for the entire circuit or for individual devices.
Using .OPTION
Use the following form to set temperature over the entire circuit; all specified simulations are performed at this temperature.
.OPTION temp=<temperature>
Example:
.OPTION temp=100
Using the temp Variable in the Element
To set temperature on an individual device, type temp=<temperature> after the device model name in the element statement, as shown in the following examples.
Examples:
R1 1 2 10K RMOD TEMP=100 QTEST 3 2 1 Q2N2222 TEMP=85
Using the SPICE2 .TEMP Statement
DR. SPICE also supports the SPICE2 .TEMP command.
Example:
.TEMP -55 25 125
This example sets up the circuit simulation at -55 °C, 25 °C, and 125 °C.
