Examples
Example 23—Parametric Sensitivity Analysis
.extract tran label=overshoot (max(v(op)) - 0.6) / 0.6 * 100
The above line specifies to extract the relative overshoot value.
.sensparam subckt=opamp inst=x_opamp1 param=w1,w2,w4,w5,w7 sort=dec
variation=1%
The .SENSPARAM statement triggers computation of the sensitivities of the .EXTRACT
quantities to parameters “w1,w2,w4,w5 and w7” of instance “x_opamp1.” The results are
presented in decreasing order, and the increment used for sensitivity calculation is 1%. The
results appear in the table at the end of the output .chi file.
