Patent ID: 7669162

Claim:
An integrated power source system analysis system, comprising: unit which calculates an equivalent circuit constant based on information related to a mesh for generating an equivalent circuit of a multilayer printed circuit board having a plurality of mounting candidate points at which a plurality of LSIs can be mounted; unit which calculates an impedance matrix with power source and ground terminals of the multilayer printed circuit board as an input by using said equivalent circuit constant; unit which selects a first LSI mounting candidate point where a first LSI is to be mounted from among said LSI mounting candidate points; and unit which sequentially selects a second LSI mounting candidate point for mounting a second LSI at which interaction with a power source supply system of said first LSI is lowest by using said impedance matrix, wherein said second LSI mounting candidate point is selected from among the plurality of LSI mounting candidate points excluding said first LSI mounting candidate point from said plurality of LSI mounting candidate points.
