The necessity for the control and minimisation of unintentional electromagnetic emissions from electrical systems has long been appreciated and much skilled effort is spent on EMI suppression. Due to the complexity of the problem, however, very little in the way of CAD tools is available to help the designer. A technique is described, based on the finite difference time domain technique, whereby the radiation levels from digital circuits may be predicted. The predicted results are compared to measurements for a trial configuration
