Provided are a method, system, and program for processing and verifying circuit designs. A circuit design specification written in a hardware definition language is received and zero delay black box code is added to the circuit design specification to position the zero delay black boxes at sequential elements. A synthesis of the circuit design specification is performed to generate a retimed implementation of the circuit design specification. The black boxes are processed in the retimed implementation to verify the synthesis of the circuit design.

Processing and verifying retimed sequential elements in a circuit design

A method and apparatus provide a digital circuit including dynamic logic that minimizes circuit-path delay, residue logic, and circuit area. The method and apparatus use a library of circuit cells to produce a digital circuit design using a mapping algorithm. The mapping algorithm firstly determines an arrangement of circuit cells to minimize the delay in the circuit design, secondly determines an arrangement of circuit cells to minimize the residue logic for the circuit design, thirdly determines an arrangement of circuit cells to minimize the circuit area for the circuit design, and then repeats the process for each node in the circuit until the best circuit design is produced in accordance with pre-determined criteria.
