Abstract

In a programmable logic array integrated circuit device, various techniques are used to increase the flexibility with which the core logic of the device can be connected to the input and/or output pins of the device. While the techniques shown greatly increase circuit flexibility, they avoid the unnecessary overhead of interconnectivity which is completely general.
