Latest Patents

Liu's latest patents include groundbreaking work in multi-instantiated block timing optimization. This innovation presents electronic design automation systems and methods for top-down timing budget flow in master-clone scenarios. In this approach, different instances of a master-clone block within an integrated circuit design are associated with varying constraint files. These files are tailored based on the unique connections of each instance with elements of the integrated circuit design, as well as the shared structure of the master-clone block. The resulting top-down timing budget flow allows for modifications to the integrated circuit design prior to the generation of physical devices.

Another notable patent is the method and apparatus for master-clone optimization during circuit analysis. This system identifies a target block with an external boundary in an integrated circuit design. The area outside this target block is transformed into a first macro, which includes both a physical library and a timing library. The target block is then represented as a single block netlist, which is optimized concerning the first macro. This process can be repeated for multiple instances of the same design IP, enhancing the efficiency of circuit design optimization.
