This record is used to set low and high limits for the values of the optimization circuit elements specified on the .OPE record. If a restricted range of allowed values is desired for a particular element it is entered on this record.
.OPLIM T1 F1 F2 T2 F3 F4 ...
where
T1 = circuit element name whose value is to be limited
F1 = lowest allowed value for element T1
F2 = highest allowed value for element T1
T2 = next element to be limited ...
Each limit set consists of the element name along with the low and high limit values.
After each new generation is created in the optimization algorithm, and before the responses of the new individuals are evaluated, the limits are imposed.
Example
; limit the range of c2 and r1 as shown:
.OPLIM c2 .001u 1.0u r1 1.k 100.k
The circuit elements named on the OPLIM Record must also be named on the OPE Record.
