A method is described which makes it possible for the card designer to identify high electromagnetic interference (EMI) potential card nets before hardware models are measured in the EMC lab. These nets can then be specially designed to reduce EMI emissions. As a result, fewer resources are devoted to EMC lab fixwork further along in the development cycle. Data processing equipment companies may not market or sell computers, peripherals or other electronic devices that do not meet the stringent FCC (Federal Communications Commission) regulations governing EMI emissions. Numerous engineering resources must usually be devoted to reducing product EMI in the EMC lab, and any analysis of high-EMI potential nets must be done manually.
