Latest Patents
One of his latest patents is titled "Method and structure for screening NFET-to-PFET device performance offsets within a CMOS process." This invention focuses on a method of screening on-chip variation in NFET-to-PFET device performance for as-manufactured integrated circuits (ICs) made using a CMOS process. The method involves defining an acceptable frequency- or period-based NFET-to-PFET device performance envelope by simulating a pair of ring oscillators, one containing only NFET transistors and the other containing only PFET transistors. These ring oscillators are fabricated into each as-manufactured IC, and during screening, their frequencies are tested and compared to the performance envelope to determine acceptability.
Another significant patent is "Slack sensitivity to parameter variation based timing analysis." This invention discloses a method, system, and program product aimed at improving IC design by prioritizing failure coefficients of slacks that lead to corrections based on their probability of failure. A sensitivity analysis is performed on independent parameters, and a failure coefficient is calculated to determine whether any timing endpoints fail a threshold test. Failing timing endpoints are then prioritized for modification according to their failure coefficients.
