EMI modeling capabilities

Modeling any circuit is an important way to evaluate a design’s performance in the early stages, and thus plays a critical role in reducing design cycle times. EMI modeling is a complex process that involves time-domain circuit analysis as well as frequency domain electromagnetic simulations of the PCB. Modeling EMI emissions makes it easier to meet EMI standard limits more quickly by reducing the number of design iterations.
