Title: The Innovations of Dick L Liu
Introduction
Dick L Liu is a notable inventor based in Saratoga, CA (US), recognized for his contributions to electronic design automation (EDA) systems. He holds a total of 3 patents, showcasing his expertise in developing innovative methods for debugging and testing integrated circuits.
Latest Patents
One of Liu's latest patents is a "Method and apparatus for debugging reconfigurable emulation systems." This invention employs field programmable gate arrays (FPGAs) to emulate prototype circuit designs. The process involves downloading a circuit netlist file to configure the FPGAs, followed by functional testing to ensure proper implementation. If discrepancies arise, Liu's method allows for debugging through the insertion of 'read-back' trigger instructions, capturing internal states for analysis without the need for recompilation.
Another significant patent is related to "Testing of integrated circuits using clock bursts." This method enables high-speed testing of sequential logic circuits, such as ASICs, by applying a series of high-speed clock signals while holding the logic input signals unchanged. This innovative approach allows for thorough testing of every path in the circuit using a conventional low-speed tester.
