Latest Patents

One of his latest patents is titled "Digital simulator circuit modifier, network, and method." This invention describes a circuit modifier and method for use with an event-driven digital logic simulator. It ensures consistent evaluation of input pin changes at state elements by automatically interposing a fictitious 0-delay defer agent at the input pin to state elements such as D Flip-Flops. The defer agent schedules events related to input state changes, allowing for a more accurate simulation process.

Another significant patent is the "Tool, system and method for dynamic timing analysis in a plural-instance." This invention provides an efficient selection of timing statements for a logic cell in response to cell pin activity. It utilizes a first storage structure coupled with a logic processor to define plural bitfield arrays corresponding to a cell pin and its possible logic levels. This ensures that appropriate timing and constraints for the logic cell are maintained during digital logic simulation.
