An Optimal O(n2)-Algorithm to Fold Special PLA’s

The development of Microelectronics made it possible to connect and integrate hundreds of thousands of electronic components in very small chips (1 cm × 1 cm, or less). This technology, called VLSI (Very Large Scale of Integration), allows the design of very complex circuits and systems. Such designs have become so complex that structured design techniques are desirable in order to improve logical-electrical correction with a reasonable cost.
