POWER SOURCE NETWORK ANALYZING APPARATUS, POWER SOURCE NETWORK ANALYZING METHOD, AND POWER SOURCE NETWORK ANALYZING PROGRAM

摘要

PPROBLEM TO BE SOLVED: To perform power source network analysis with accuracy and efficiency, even if a LSI circuit has a larger scale and enhanced degree of integration. PSOLUTION: An area partitioning processing unit 102a establishes a power source network analysis object area of the LSI and equally partitions the power source network analysis object area according to the number or size of partitioned areas specified by a user, or according to a user's specification. A border processing unit 102c extracts and adds a range-of-influence part of a power source network that can electrically influence a border with a power source network area adjacent to the partitioned area partitioned by the area partitioning processing unit 102a. A modeling processing unit 102d performs processing for resistance modeling of the partitioned area or the correction spot with a range-of-influence part added thereto by the border processing unit 102c. A power source network analyzing processing unit 102e analyzes a resistance model modeled by the modeling processing unit 102d, and calculates potential of each via as a current source to a load element.
