Logic blocks in a synthesized logic design that have specified inputs are identified by performing a two-pass analysis of the synthesized logic design. A number of levels is specified. A forward linear trace is performed to identify inputs at each level for each logic block, without regard to the specific function of each logic block. A list of potential equivalency points is generated from the forward linear trace. A reverse logical trace is then performed from the potential equivalency points to identify equivalent logic. When no equivalent logic exists, the analysis can specify one or more additional inputs, or one or more missing inputs, to determine whether similar logic exists that could be replicated and modified to achieve the desired function. |
