Abstract :
A design method using both logical optimization and optimized topological arrangements is described. Starting from a minimized Boolean function, a synthesis of an optimized well-structured network is obtained. The most original aspect of this approach is a transistor merging procedure leading to a nonseries-parallel network while maintaining a systematic layout. An extension to the synthesis of several functions relies on transistor mergings between functions and allows comparisons with a PLA implementation. Gains in both area and performance are obtained
