Sensitivity Analysis of Parameters
Designers need sensitivity information for design parameters (parameters they can act upon).
The .SENSPARAM command computes the sensitivity of voltages/currents and extracts to
these design parameters.
The first simulation is the nominal simulation, using nominal values for the parameters. The
following simulations are sensitivity analysis runs where Eldo applies a small variation to one
of the P parameters, keeping all others to their nominal value, and computes the sensitivity of
the targets relative to the current parameter. Therefore there are 1 + P simulations. The
sensitivity results represent the variation of the extracted value for a variation of 1% of the
parameter value.
