Latest Patents
Pruehsner holds a patent for an "Automated test equipment digital tester expansion apparatus." This invention provides a scan-based logic test apparatus designed for use with automated test equipment (ATE) digital testers. The apparatus is embodied in a test card that can be plugged into a bus slot within a computer. The computer features permanent memory for storing scan-based pattern data, including serial input and expected serial output pattern data. The test card includes an I/O interface control that connects the test card to the computer and the digital tester, allowing for efficient data retrieval and control signal supply. Additionally, the test card is equipped with SRAM memory to store the scan-based pattern data and an IC device interface for coupling the IC device to the memory and control. This setup enables the collection of responsive serial output pattern data, which is then compared to expected data to determine pass/fail outcomes for the IC device under test.
