Abstract:
1. A method for determining a total output noise of a circuit, the method comprising: simulating the circuit using information representative of an integrated circuit design corresponding to the circuit to identify an input noise contribution; separating, using a processor, the input noise contribution of the circuit into a first noise contribution and a second noise contribution, wherein a first noise profile of the first noise contribution decreases as a function of frequency and a second noise profile of the second noise contribution is constant as a function of frequency; determining, using the processor, a first output noise of the circuit using the first noise contribution, wherein the first output noise is determined in a frequency domain; determining, using the processor, a second output noise of the circuit using the second noise contribution, wherein the second output noise is determined in a time domain; and determining, using the processor, the total output noise of the circuit based on the first output noise and the second output noise.
