Abstract
Customization of structured ASIC devices using pre-process extraction of routing information. Embodiments of the invention can enable a router that can automatically extract a routing graph for a structured ASIC, where the routing graph represents available routing resources on fixed metal layers. The routing graph can be extracted as a pre-process, and saved in a technology file for later use by the router. Additionally, each unique fixed metal wire type found in the layout can be characterized with a master wire definition, including resistance and capacitance estimates. In some embodiments, a global-routing graph can further be extracted from a detailed routing graph.
