ABSTRACT:
In order to increase routing flexibility for the output signals of logic modules in programmable logic array integrated circuit devices, the output signal of each logic module can be swapped with the output signal of another logic module by a first level of signal swapping circuitry. The output signals of the first level of swapping circuitry can be further swapped with output signals of other first level swapping circuits by a second level of signal swapping circuitry to provide still more routing flexibility for the logic module output signals.
