ABSTRACT:
A system and method for replacing a malfunctioning logic device with a substitute logic device. The system provides a replacement assembly that contains a complex programmable logic device, a programming port and a pin configuration. The pin configuration selected matches the pin configuration of the malfunctioning logic device being replaced. The programming port on the replacement assembly is attached to a computer. Using software on the computer, the complex programmable logic device can be programmed with the same logic functions as were present within the malfunctioning logic device. Consequently, a single replacement assembly can be used to replace hundreds of different types of logic devices. This provided a cost efficient manner to produce replacements for obsolete logic devices that are no longer commercially available.
