Latest Patents

Vijay's latest patents include innovative methods for estimating delays in design under tests (DUTs) using machine learning. One of his notable inventions is a system that accesses multiple DUTs, each comprising various logic blocks. For each DUT, a combinatorial path is identified, connecting one or more logic blocks. A feature vector is generated, which includes values of orthogonal features representing the characteristics of the combinatorial path. The system compiles each DUT for emulation, measuring the delay of its combinatorial path. These measured delays, along with the corresponding feature vectors, are utilized to train a machine learning delay model. This trained model is designed to receive a combinatorial path of a DUT as input and generate an estimated wire delay as output. This approach leverages machine learning to predict delays in electronic designs, significantly improving the efficiency and accuracy of delay estimations.

Another patent focuses on a delay estimation system that estimates the delay of a DUT for an emulation system. This system receives logic blocks of the DUT and a combinatorial path connecting one or more of the logic blocks. It applies a delay model to a feature vector representing the combinatorial path, where the delay model can determine the delay of the combinatorial path. The system generates a timing graph using the determined delay and provides this timing graph to a compiler for placement and routing of the DUT.
