<p>The Internet is used to test an integrated circuit chip that is provided with boundary scan circuitry and plugged into a circuit board at a customer's location. A host computer at the manufacturer's location runs a web page server having the ability to remotely test a customer's chip. The process is initiated by the customer connecting the circuit board to his own computer and logging onto the web site. The customer transmits customer identification and other data to the web server, which then transmits a downloader program and a JAVA program script to the customer's computer. The customer's computer then uses the downloader program to transmit high and low level device data describing the functionality of the chip to the host computer, which then generates and transmits a set of suitable test vectors to the customer's computer. Then, the customer's computer tests the chip using the boundary scan circuitry and test vectors and transmits the test results to the host computer, which then produces and transmits an evaluation of the results to the customer's computer.</p> |
