Latest Patents

David K Johnson holds a patent for a "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 enforces consistent evaluation of input pin changes at state elements. The invention automatically interposes a fictitious 0-delay defer agent or processor at the input pin to state elements such as D Flip-Flops. The simulator handles the interposition of the defer agent by scheduling events related to input state changes on a special time or task queue. This queue is not processed until after all other events have been executed for the current time. The defer agents ensure that events that normally propagate to the input pin of a state element are delayed until all other normal simulation events are processed. This innovation allows for consistent evaluation of pin changes at state elements.
