Latest Patents

One of his latest patents is titled "Hierarchical order ranked simulation of electronic circuits." This method provides a way to simulate integrated circuit designs by determining a node order ranking of nodes in a netlist. The circuits can be partitioned based on this ranking, allowing for optimization in simulation. The hierarchical data structure built from this partitioning enables efficient analysis and export of simulation data without the need for linear network reduction, which often leads to accuracy loss.

Another significant patent is "SPICE optimized for arrays." This innovation optimizes memory arrays for SPICE simulation by modeling them as collections of boundary elements. By tracking the cell states of memory cells connected to a particular array terminal, accurate simulation results can be achieved without simulating each cell independently. This method minimizes memory and CPU usage during simulations by eliminating references to unoccupied cell states.
