Abstract
A program compatibility recognition system for an integrated circuit. A programming device 4, including programming software 8, is used to program an integrated circuit 2 such as a field programmable gate array. The programming device provides a revision code 12 to a detection circuit 10 on the integrated circuit. The detection circuit determines if the revision code indicates that the software is compatible with the integrated circuit and, if so, generates an appropriate control signal to permit the programming device to program the integrated circuit.
