In this analysis, (actual SENS.SCP file), after running a reference simulation, each parameter
is perturbed and another analysis is run. For each measurement
vector, the difference between the reference and the perturbed
result, the sensitivity, is saved. This results in a number of
simulations equal to the number of parameters that have tolerances.
As a matter of convention, each tolerance
is taken as the 3 sigma value, or 3 standard deviations and we
report the Sensitivity results as though they were also 3 sigma.
The sensitivities for each parameter are reported for all measured
vectors in descending order of magnitude in the IsSpice4 output
file. The sensitivities can be tabulated for each measured vector
or for each parameter.
