Abstract

A user-programmable interconnect architecture, which may be used for logic arrays for digital and analog system design, is disclosed. In one embodiment, a plurality of logic cells or modules in a matrix are connected by vertical and horizontal wiring channels. The wiring channels may in turn by programmed by the user to interconnect the various logic cells to implement the required logic function. The wiring channels comprise wiring segments connected by normally open reconfigurable programmable elements situated at the intersection of any two segments to be connected. Sensing circuitry and wiring may be included to allow 100% observability of internal circuit nodes, such as module outputs, from an external pad interface.
