Caleb Crome has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and device for test vector analysis
    Patent number: 6197605
    Abstract: A method and device for testing and manufacturing integrated circuits such as microprocessors, memories, ASICs, programmable logic, and other types of integrated circuits. A test system is designed to test the relevant integrated circuit. A device under test emulator responds to the test system. If modifications are needed, the test system can be modified, and used to test actual devices.
    Type: Grant

  • Buffer for identification of pin contentions in circuit design and simulation
    Patent number: 5909375
    Abstract: A system and method for making and using integrated circuits using a modeling system. The system utilizes a pin test buffer. The pin test buffer inputs external inputs to a pin, and outputs to the same pin from the device. If contention is noted between the system inputs to the pin, and outputs from the device to the pin, contention error notices are provided to the user.
