ABSTRACT:
A system for modifying a printed circuit board allows parallel design of the printed circuit board and a programmable gate or logic array used on the circuit board. The printed circuit board design can be fixed before the gate array design is complete, which allows for flexibility in pin assignments of the high density integrated circuit mounted on the circuit board. Each pin of the gate array that can vary has a pair of vias connected by a conductive track. Changing signal paths requires cutting this track and using a jumper to make the new connection.
