Power supply network analysis method, computer program for executing power supply network analysis method, recording medium, and power supply network analysis apparatus

摘要

Disclosed are a suitable power supply network analyzing method which executes power supply network analysis of a large-scale circuit in a short period of time with fewer computer hardware resources, a computer program which executes the power supply network analyzing method, a storage medium and a power supply network analyzing apparatus. An entire net list is extracted by converting circuit elements to current sources and dividing power supply lines into resistor elements, based on design information and physical information. Next, a portion of the power supply network which includes the current sources and in which the resistor elements are connected in series is selected. A partial net list is extracted to execute circuit compression by allocating the current sources to circuit elements in the selected portion. Then, the compressed net list is set in the entire net list to simplify the entire net list and power supply network analysis is performed. In case where analysis of the partial net list has not been completed, the results of the analysis of the entire net list is set to both end nodes and analysis is executed again. This can ensure hierarchical analysis.
