Latest Patents
One of his latest patents is titled "Estimating Clock Skew." This invention relates to a method and an apparatus for estimating clock skew in circuits. The method involves obtaining a basic clock skew for each clock tree in the circuit and determining whether two units are in the same clock domain. If they are in different domains, the clock skew is estimated based on the larger basic clock skew of the corresponding clock trees. If the units are in the same domain, further analysis is conducted to assess their hierarchical logic blocks. This method enhances the accuracy of clock skew estimation, thereby improving circuit design efficiency.
Another significant patent by Hong Wei Dai is the "Method and Apparatus for Detecting Contradictory Timing Constraint Conflicts." This invention provides a systematic approach to detecting timing constraint conflicts by establishing a directed graph from a timing constraint file. The method involves searching for directed cycles within the graph and determining if any timing constraint conflicts exist based on the weights of the directed edges. This innovative approach can automatically detect conflicts with a high degree of accuracy, significantly reducing design turnaround time and resource expenditure in ASIC projects.
