Latest Patents

One of his latest patents is titled "Scan test circuits for use with multiple frequency circuits." This invention introduces a scan path test architecture that allows for testing circuits using multiple system clocks with different frequencies. It includes a controller that disables the system clocks during a test cycle and a master clock that generates a signal frequency for each circuit module. This innovation eliminates the need for partitioning scan paths between modules and synchronizing system clocks.

Another significant patent is the "Method and apparatus for testing passive substrates for integrated circuits." This system provides a method for testing the continuity of interconnecting nets on a substrate intended for multi-chip technology. The system involves coupling a test pad to the net being tested and sensing the voltage of the net to determine continuity. If an erroneous interconnection is present, the voltage will fluctuate, indicating a problem.
