Method And Apparatus For Simulating Quasi-Periodic Circuit Operating Conditions Using A Mixed Frequency/Time Algorithm
View pageUS Patent:
8195440, Jun 5, 2012
Filed:
Feb 17, 2009
Appl. No.:
12/372608
Inventors:
Dan Feng - Los Altos CA, US
Joel R. Phillips - Sunnyvale CA, US

Assignee:
Cadence Design Systems, Inc. - San Jose CA
International Classification:
G06F 17/50
US Classification:
703 14
Abstract:
Described is a process for performing an improved mixed frequency-time algorithm to simulate responses of a circuit that receives a periodic sample signal and at least one information signal. The process selects a set of evenly spaced distinct time points and a set of reference time points. Each of the reference points is associated with a distinct time point, and a reference time point is a signal period away from its respective distinct time point. The process finds a first set of relationships between the values at the distinct time points and the values the reference time points. The process also finds a second set of relationships between the values at the distinct time points and the values at the reference time points. The process then combines the first and second sets of relationships to establish a system of nonlinear equations in terms of the values at the distinct time points only. By solving the system of nonlinear equations, the process finds simulated responses of the circuit in time domain.
