Title: The Innovations of William C. Carrell
Introduction
William C. Carrell is a notable inventor based in Newark, California. He has made significant contributions to the field of emulation circuits, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
Carrell's latest patents include an "Emulation Circuit with a Hold Time Algorithm" and a "Logic Analyzer and Shadow Memory." These patents describe a circuit for an emulation system that features a logic element with RAM, a lookup table, an optional delay element, and a flip-flop/latch. The flip-flop/latch can function as either a flip-flop or a latch, equipped with separate set and reset signals. The delay element is designed to insert a selectable amount of delay into the data path of the logic element, effectively reducing race time problems. Additionally, the logic elements can be combined to share input signals, thereby increasing the size of the RAM. The improved circuit also includes a playback memory that stores multiple copies of sampled data from a logic element, allowing for the playback of emulation data for debugging purposes. Multiple read ports connected to the logic elements enable users to read data during emulation in a time-multiplexed manner, while the input/output pins can be time-multiplexed to carry multiple signals, either unidirectionally or bidirectionally.
