20090299718 | Power source network analyzing apparatus, power source network analyzing method, and power source network analyzing program - An area partitioning processing unit equally partitions a power source network analysis object area of an LSI according to the number or size of partitioned areas specified by a user or partitions the power source network analysis object area according to the user's specification. A border processing unit extracts and adds a range-of-influence part of the power source network that can electrically influence a border between the partitioned area partitioned by the area partitioning processing unit and an adjacent power source network area. A modeling processing unit performs processing of resistance modeling of the partitioned area or a correction spot with the range-of-influence part added thereto by the border processing unit. A power source network analyzing processing unit analyzes a resistance model modeled by the modeling processing unit and calculates potential of each via as a current source to a load element. | 12-03-2009 |
