How to Reduce EMI in SMPS 

A higher-speed SMPS is smaller, lighter, and cheaper, but higher speeds introduce new challenges, such as unwanted EMI. Suppression of EMI by traditional "solder-and-see" workflow is costly, time-consuming, and nondeterministic. Thus, we must transition to a new workflow - namely a series of "virtual prototypes" using post-layout simulation - that is cost-effective, faster, and yields deeper insights to suppress EMI.
