Latest Patents
One of his latest patents is titled "System and method for accelerating timing-accurate gate-level logic simulation." This invention involves a computer executable tool that analyzes a gate-level netlist and utilizes the analysis results to accelerate timing-accurate gate-level logic simulation through parallel processing. The tool identifies key elements in the netlist, such as netlist wires at partition boundaries for value propagation, wires whose activities should be suppressed for better performance, and upstream flip-flops for partition boundaries to reduce synchronization overhead. This information significantly improves parallel simulation performance.
Another important patent is "Systems and methods for fixing X-pessimism from uninitialized latches in gate-level simulation." This invention addresses the issue of unknown (X) propagation from uninitialized latches in gate-level simulation. It determines whether the Xs lead to false Xs due to X-pessimism. For those generated due to X-pessimism, the simulation results are corrected, ensuring that they match real hardware behavior. This greatly reduces engineers' efforts in debugging X issues.
