Or just hire an engineer who gets it and understand EMI

Simulations are highly subject to the old GIGO limitations. Further, the quality of simulation software to date has not been up to accurately predicting complex systems with communications and distributed control schemes involved. The historical approach has been "divide and conquer", estimating the impact of each sub-part of a larger system. Still, such approaches have yielded only several-order-of-magnitude accuracy because of the significant effects of simple arrangement and packaging issues. Until we can get past the "We must be sure it is right the first time, but you cannot develop a circuit or packaging using costly features!" mentality, it is my considered opinion that simulation for EMI/EMC will only expose the efforts of designers that are not meeting the "motherhood and apple pie" design parameters.

EMI simulations will help a lot in reducing the R&D cost and time. The simulation tools for the automotiive industry are in the baby phase and lot more inputs are required from practical live field studies. These are on mobile and their ambience varies in a wide range it is more complicated to predict its nature using simulation alone.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
