Latest Patents

One of Yi's latest patents focuses on integrating machine learning delay estimation in FPGA-based emulation systems. This innovative method estimates delays in design under tests (DUTs) by accessing multiple DUTs, each comprising various logic blocks. For each DUT, a combinatorial path is identified, and a feature vector is generated to represent the path's characteristics. The system compiles each DUT for emulation and measures the delay of its combinatorial path. These measured delays, along with the corresponding feature vectors, are utilized to train a machine learning delay model, which predicts delays in electronic designs.

Another notable patent involves emulation performance analysis using an abstract timing graph representation. This method computes time delays for each path in a circuit design and determines a commonality score based on the segments shared between paths. Additionally, it generates a graphical representation of the paths, providing a visual interface to represent the circuit design effectively.
