Abstract
A system and method of optimizing a circuit design. The design may be coded in register transfer language (RTL) code. First the design code representing an integrated circuit design to be optimized is retrieved and sequentially searched for decision constructs. As each decision construct is encountered, it is checked to determine whether both branches drive a common output in response to a common select signal. If so, a determination is made whether the decision construct includes a common arithmetic operation in said both branches, and so, may be optimized. A construct library for a corresponding optimized construct and the selected decision construct is replaced with an optimized construct. After all of the decision constructs are checked, the optimized design code is stored, replacing the original design code. The optimized RTL design code has an identical logic function to the original retrieved RTL code.
