The authors describe a rule-based logic reorganization system LORES/EX, which transforms an existing logic circuit into one that is dependent on other technology. The system can be not only flexibly adjustable to technology changes, but also has several special features as follows: (1) introduction of the circuit standardization rules makes the size of the rule base much smaller, and makes the description and modification of the rules easier; (2) application of conflict resolution based on evaluation functions contributes to the generation of high-quality circuits; and (3) introduction of the automatic partitioning of a circuit into subcircuits enables the reorganization of the circuit with some 10 K gates in a practical computation time.>
