In general most logic networks are comprised of highly repeated subnetworks. Each different subnetwork can be represented by a distinct type of macromodel. A distinct type of macromodel is defined as a macromodel in which the subnetworks represented by the macromodel must have identical topological structure. This kind of macromodel is called the Topological Symbolic Macromodel (TSM). TSM can be extended to a Functional Symbolic Macromodel (FSM) to include a wider class of subnetwork. This FSM allows certain topological variations as long as the logical function of the subnetwork, such as NOR, NAND, AOI, etc. remains the same. Consequently, the large network can be represented by fewer macromodels, thereby facilitating savings in storage and computation time.
