Sweeping Parameters Examples<br />

Sweeping Parameters Examples<br />

To perform several simulations while sweeping one or several circuit parameters (multiple<br />

sweep) use the .STEP command.<br />

The following types of sweeps are supported:<br />

• Temperature sweep specified by TEMP keyword. Dipole (R, C, L) component whose<br />

value is swept specified by the DIPOLE name.<br />

.STEP TEMP | DIPOLE INCR_SPEC<br />

• MOS—name of the MOS component whose W or L parameter is swept:<br />

.STEP MOS W|L INCR_SPEC<br />

• Parameter PARAM_NAME of model MNAME is swept:<br />

.STEP MNAME PARAM_NAME INCR_SPEC<br />

• PAR_NAME is a parameter name defined through the .PARAM command:<br />

.STEP PARAM PARAM_NAME INCR_SPEC<br />

• To sweep a device parameter:<br />

.STEP E (device, parameter_name) INCR_SPEC<br />

• To sweep a parameter defined through .PARAM:<br />

.STEP P (global_parameter) INCR_SPEC<br />

• To sweep a model parameter:<br />

.STEP M (model_name, parameter_name) INCR_SPEC<br />

• To sweep different variants of a library:<br />

.STEP LIB (lib_name) INCR_SPEC<br />

.STEP Sweeping Parameters Examples<br />

Some examples of sweeping parameters with the .STEP command.<br />

• This example specifies that the value of resistor r1 will be swept from 1kΩ to 2kΩ with<br />

a step of 1kΩ, and then from 2kΩ to 4kΩ with a step of 500Ω:<br />
