ELECTROMAGNETIC RADIATION ANALYSIS DEVICE, ANALYSIS METHOD, AND ANALYSIS PROGRAM

摘要

PPROBLEM TO BE SOLVED: To precisely predict the amount of the electromagnetic radiation from a printed circuit board. PSOLUTION: This electromagnetic radiation analysis device analyzes electromagnetic radiation of a printed circuit board and has a power source-ground system layout extraction part 3, which extracts layout of a power source-ground system from inputted layout information, edge part extraction part 4 and 5, which extract an edge part of the power source-ground system at the extracted layout; a power source-ground system voltage change calculation part 7, which calculates voltage change between ground plane and power source plane about the extracted power source-ground system edge part for each analysis frequencies, based on the value of the inputted power source current; a common-mode current calculating part 8, which calculates value of common mode current based on the calculated voltage change; and an electromagnetic radiation field intensity calculation part 9, which calculates the intensity of electromagnetic radiation field arising at the ground plane, based on the value of the common-mode current calculated.
