Patent number: 6854103Abstract: An apparatus and method for automatically generating a visual representation of a resistance network and an equivalent point to point resistance for any set of terminals on the resistance network are provided. With the apparatus and method, a cell layout is input to a resistance/capacitance (RC) extraction tool. The RC extraction tool extracts the RC parasitics from the cell layout and inputs them into a resistance network visualization and analysis tool. From the RC parasitics, a graph data structure representation of the resistance network is generated. The graph data structure of the resistance network may then be reduced using, for example, a single layer series and parallel reduction, all layers series and parallel reduction, layer specific reduction, or the like. Following reduction, if any, a visual representation of the resistance network is generated using the graph data structure. Thereafter, equivalent point to point resistance for any set of terminals on the resistance network may be generated.Type: GrantFiled: December 30, 2002Date of Patent: February 8, 2005Assignee: LSI Logic CorporationInventor: Andres Robert Teene

Publication number: 20030210695Abstract: A method is described for forwarding a data packet within a subnetwork (S) of interconnected cell switching nodes (1,2,3,4), surrounded by edge packet routers (A,B,C,D,E), which are further surrounded and part of a data packet network of routers. Said data packet enters said subnetwork via an ingress edge packet router (B), passes through at least one cell switching node (1), and leaves it via at least one destination egress edge packet router (A,C,D,E). The method includes the steps of associating a destination forwarding tag to said data packet, of deriving a sequence of fixed length cells for further transmission to said at least one cell switching node (1), of dynamically analyzing said destination forwarding tag for elaborating a packet cell forwarding decision applicable to all cells of said sequence, and thereby performing a subsequent transfer action of said all cells, to at least one outgoing link.Type: ApplicationFiled: April 25, 2003Publication date: November 13, 2003Applicant: ALCATELInventor: Michel Andre Robert Henrion
