1. A method of performing a glitch check in simulating a circuit, the method comprising the following steps: determining a current maximum and minimum values for an optimization parameter of the circuit; determining a signal characteristic value for circuit simulation based on the maximum and minimum optimization parameters; determining a current averaged optimization parameter; calculating a prime criterion parameter based on the optimization parameters and the signal characteristic value; determining whether the prime criterion parameter converges to a prescribed range; if the prime criterion parameter converges into the prescribed range then parsing measurement results from the circuit simulation; if the prime criterion parameter does not converge into the prescribed range; simulating the circuit based on the current optimization parameter calculating a new signal characteristic value using the circuit simulation; determining the results of the circuit simulation based on the signal characteristic value; and setting the current optimization parameter to a new optimization parameter in response to the signal characteristic value.
