Patent number: 6516454Abstract: A method of accurately estimating a time delay caused by a target cell where a target supply voltage is applied to the cell. Time delays, caused by a representative cell, are represented as a function of supply voltages applied to the cell, thereby deriving an approximation function k1. An interpolation function k2 is derived from the approximation function k1 by reference to two points P1 and P2. P1 indicates a time delay T1 caused by the target cell where a supply voltage V1 is applied thereto, while P2 indicates a time delay T2 caused by the target cell where a different supply voltage V2 is applied thereto. Thus, the interpolation function k2 represents the time delays caused by the target cell as a function of supply voltages. And by using this interpolation function k2, a time delay caused by the target cell at the target supply voltage can be estimated accurately.Type: GrantFiled: November 17, 2000Date of Patent: February 4, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masaaki Hirata, Ryuichi Yamaguchi

Patent number: 6292928Abstract: A line capacitance is estimated in consideration of an influence of an adjacent line in rough routing, so that line paths can be determined so as to be free from a timing error. A routing graph is generated from a target integrated circuit, and line paths of cell-to-cell lines are initially determined on the basis of a passage cost set with regard to each of edges of the routing graph. With regard to each edge of the routing graph, the number of cell-to-cell lines passing through the edge is obtained as a line density, and a line capacitance of each line path in view of the influence of an adjacent line is estimated on the basis of the line density. It is verified whether or not there is a timing error with a delay time estimated, and when the integrated circuit does not satisfy a predetermined timing constraint, the line paths are re-determined with the passage cost of each edge allowed to be affected by the line capacitance.Type: GrantFiled: January 11, 1999Date of Patent: September 18, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Ryuichi Yamaguchi, Keiichi Kurokawa
