Latest Patents

One of his latest patents is titled "Clock skew verification methodology for grid-based design." This invention provides a method and apparatus for determining clock insertion delays in microprocessor designs that utilize a grid-based clock distribution. The process involves partitioning the complete clock net into a global clock net and several local clock nets. It includes simulating loads for each local clock net, simulating the global clock net, and combining these simulations to form the complete clock net. The method evaluates the combination to check for convergence and stores the simulation results in a Clock Data Model. If the results do not converge, the method re-simulates the local and global clock nets. This innovative approach allows for the analysis of the complete clock net to predict clock skew for data transfer paths, facilitating potential redesigns.

Another significant patent is "Controlled PMOS load on a CMOS PLA." This invention describes a programmable logic array (PLA) that receives data input signals from input registers and generates corresponding minterms. The minterms are combined to form a sum of products, which are then clocked out before the end of each clock cycle. The design includes NOR gates with NMOS transistors and a PMOS load transistor that operates based on timing signals, enhancing the efficiency of the PLA.
