Abstract
A method for programming an in-system programmable logic device (IsPLD), using an automatic tester, includes the steps of: (i) expressing a fuse map for an IsPLD in the form of one or more test vectors to be applied in an automatic tester; (ii) including in a system board unprogrammed the IsPLD; (ii) mounting the system board on an automatic tester in a configuration for system testing; (iii) receiving into the automatic tester the test vectors; and (iv) and apply the test vectors to program the IsPLD. The system board with the IsPLD so programmed can proceed immediately to final test. In addition, a method is provided to translate a JEDEC file to a bit stream file, thereby achieving a eight-fold saving in storage requirement.
