ABSTRACT:
A pragma is used to pass circuit type information to a Computer Aided design (CAD) tool. The CAD tool then selects an alternate synthesis or timing algorithm based on the circuit type, and a circuit design for use in an electronic device is created. Practical applications include using alternate algorithms specific to different circuit types, such as, Cyclic Redundancy Checks (CRC), bus arbiters, state machine encoders, barrel shifters, preferential cores, and legacy circuits. One embodiment generates informative messages for the designer once the circuit type is known and the analysis is performed. Another embodiment generates pragmas that can be later used by circuit designers in future circuit designs.
