EMI engineers are struggling everyday with complex radiation problems that fails critical products to pass EMI certification and causes big loss of profit. Advances in EMI engineering are following a similar trend like Signal-Integrity engineering 10-years ago when tools nowadays became capable of providing accurate predictive simulations in a reasonable amount of time. With careful engineering utilizing cutting-edge full-wave field-solver software: Momentum (MOM) [1], EMpro (FDTD) [2] along with a hardware boost using heterogeneous massive CPU/GPU parallel processing (CUDA) technology [3], we can move the EMI teams from the back-end black-magic to a successful cost-effective front-end design. This paper presents an innovative process (Virtual-EMI lab) for pre-and post-tape-out providing the designers with an early stage EMI-suppression matrix (on-chip, on-package and on-board enablers) to find the optimum trade-off between performance and cost. It is also observed that trade-off between SI/PI and EMI is the common signature of nowadays High-speed-Digital design techniques.
