17. The method of logic synthesis of claim 16, and further comprising: prior to transforming the nodes having the attribute indicating the structure dominance level, transforming the nodes having the attribute indicating the direct mapping level; and if direct mapping for a node fails, transforming the node as though it had the attribute for the structure dominance level.
17. The method of logic synthesis of claim 16, and further comprising: prior to transforming the nodes having the attribute indicating the structure dominance level, transforming the nodes having the attribute indicating the direct mapping level; and if direct mapping for a node fails, transforming the node as though it had the attribute for the structure dominance level. 19. The method of logic synthesis of claim 17, wherein the step of transforming the nodes having the attribute indicating direct mapping further comprise: searching a target technology library for exact matches to the nodes and mapping any exact matches located to the nodes; after searching for exact matches for a node, determining if any exact matches were located; and if no exact matches were located for a node, expanding the node by reducing fan-in to allow location of exact matches and adding the exact matches to the node.
