Both the first and second multiplexer include a select input, both of which are connected to the output of a two-input logic gate of a first type having first and second data inputs. The inputs to the first and second two-input multiplexers are sourced with data signals from a first group. One input of each of the logic gates is sourced from a data signal of a second group and the other input of each of the logic gates is sourced from a data signal of a third group. A third two-input multiplexer has its first and second data inputs connected the outputs of the first and second multiplexers, respectively. A select input of the third two-input multiplexer is connected to the output of a two input logic gate of a second type having first and second data inputs. The output of the third two-input multiplexer is connected to a first data input of a fourth two-input multiplexer having a HOLD1 input coupled to its select input. Its output is and a CLEAR input are presented to an AND gate whose output is connected to the second data input of the fourth two-input multiplexer and to the first data input of a fifth two-input multiplexer. The select input of the fifth two-input multiplexer is connected to a HOLD2 input. Its output and the CLEAR input are presented to an AND gate whose output is connected to the second data input of the fifth two-input multiplexer and to an output node. The CLEAR, HOLD1 and HOLD2 inputs are defined by combinations of signals from a data signal of a third group which may contain a data signal of one of the other groups.

摘要： 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 be programmed by the user to interconnect the various logic cells to implement the required logic function. The wiring channels comprise wiring segements connected by normally open 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. A universal function module may be configured to implement the popular logic functions and has a physical layout which is conducive to custom circuit design.
