Latest Patents

One of his notable patents is the "Scalable, partitioning integrated circuit layout system." This innovative system modifies a netlist describing an IC as a hierarchy of circuit modules. It combines clusters of cells to form larger cells, reducing the overall number of cells in the IC. This reduction leads to a decrease in the time required to generate an IC layout. The system generates a trial layout based on the modified netlist and estimates the substrate area required for each module. It divides the IC design into several partitions and creates a partition plan that allocates substrate space based on the estimated requirements. Additionally, it creates a timing budget that allocates signal path timing constraints among the partitions. Each IC partition is then laid out independently to satisfy its spatial and timing constraints, resulting in a complete IC layout.

Another significant patent is the "Method for generating a partitioned IC layout." This method quickly produces a trial layout that satisfies various spatial and power constraints, while timing constraints are not initially considered. The trial layout serves as a basis for estimating the sizes and positions of substrate areas needed for the IC modules. The design is divided into several partitions based on the proximity of modules in the trial layout. A floor plan is created to impose spatial constraints on each partition, and a timing budget allocates timing constraints based on delay estimates. The partitions are then placed and routed in accordance with the imposed constraints.
