Abstract

An automated system for designing digital logic from a user input functional specification. The input to the system is a specification that describes the input and output signals of the desired circuit, the type of logic gates and flip-flops to be used, and optional design controls such as "NO GLITCHES". Using a highly-constrained exhaustive search technique and a built-in logic simulator, the system automatically finds the simplest possible circuit that meets the user specification. The output of the system is at least a schematic drawing of the minimal logic circuit. The system is able to design any type of digital logic: combinational, sequential, synchronous or asynchronous.
