Claim One:
1. A method comprising: using a circuit recognition engine running on a computerized device, detecting dominant devices in an arc under consideration; perturbing a device parameter value of each of said dominant devices, simulating said arc and making performance measurements to obtain a measure of sensitivity of said performance measurements to said perturbing said device parameter value of each of said dominant devices, using said computerized device; calculating, using said computerized device, overall sensitivity of said arc using an equation s total = ∑ i ∈ D ⁢ s i 2 where s total is said overall sensitivity, D comprises a set of said dominant devices, and s i is a measure of sensitivity of said performance measurements to said perturbing said device parameter value of each of said dominant devices; and calculating, using said computerized device, an estimate of sensitivity error using an equation comprising: Error = s total - s total 2 + ( S v - ∑ i ∈ D ⁢ sign i · s i ) 2 where S v is overall sensitivity of said arc when all device parameter values of all devices are perturbed simultaneously, and sign i is an estimated positive or negative sign of s i based on direction of perturbation.
