  • Logic Synthesizer
    Patent number: 4703435
    Abstract: Logic is synthesized from a flowchart-level description by first generating an AND/OR logic design, simplifying the AND/OR logic, converting the AND/OR logic to NAND or NOR logic, applying particular sequences of simplifying transformations to the NAND or NOR logic, converting the simplified NAND or NOR logic to a target technology, and simplifying the target technology where possible. The end result is an interconnection of primitives of the target technology in a language from which automated logic diagrams can be produced.
