Title: The Innovations of Toshimitsu Masuzawa
Introduction
Toshimitsu Masuzawa is a prominent inventor based in Hyogo, Japan. He has made significant contributions to the field of integrated circuit design, holding 2 patents that showcase his innovative approach to enhancing testability in semiconductor technology.
Latest Patents
Masuzawa's latest patents include an integrated circuit with design for testability and a method for designing the same. This invention features a test controller equipped with a test plan generating unit that creates a test plan for a data path designed with fixed control testability. The test plan consists of three phases: the propagation of a test vector to a data input, the execution of a test, and the propagation of an output response for each test object module. This design allows the integrated circuit to supply a test plan as a time series of control signals, thereby shortening test execution time and enabling testing at the circuit's normal operational speed.
Another notable patent is for a testable integrated circuit and an integrated circuit design-for-testability method. This invention provides an apparatus for testing integrated circuits at actual operating speed while minimizing the length of the test sequence and achieving high fault coverage. It includes a state register assumed to be controllable and observable, along with a set of test patterns for a combinational circuit. The design incorporates an invalid-state generation logic circuit to produce states that cannot be set by normal transitions, enhancing the testing process.
