Latest Patents

One of his latest patents is a "Method for generating an optimized integrated circuit cell library." This patent describes a cell library that is optimized for specific operating characteristics. The process involves dividing a stimulus file into multiple simulation run files, which are then distributed across several computer workstations to enable parallel simulation of the cell. The netlist of each cell is parameterized, allowing for modifications and resimulations to better align with specific operating characteristics. A cost function is utilized to evaluate the quality of the cell design, and simulated annealing is employed to generate new simulation parameter values. This iterative process continues until the best design is selected for a new cell library.

Another significant patent is the "Method of selecting device threshold voltages for high speed and low overall power." This method focuses on identifying critical paths based on predetermined timing criteria. Transistors outside these critical paths maintain a high threshold voltage to minimize static power drain, while those within the critical paths are selected to have a lower threshold voltage for faster switching. Although this results in increased static power consumption, the trade-off is accepted for enhanced speed. The integrated circuit is thus optimized for higher frequency operation with reduced overall power consumption.
