Electromagnetic effects verification of complex electronic systems, such as avionics, military systems, entire aircraft, and automobiles is already an expensive process, and is becoming more so. The biggest issue is that verification by testing requires the availability of expensive hardware, and if the system does not meet the requirements, it is expensive to redesign and retrofit the equipment so that it will pass the test. Testing itself is also expensive, and even if the system passes the test, the test does not generally give the system developer an understanding of the electromagnetic interaction involved, so that he can qualify, for example, future derivative or similar systems.
It is therefore desirable to perform a virtual verification of the virtual system before hardware is built, in order to ensure that the system will pass the verification testing.
The paper presents the concepts of virtual prototyping of electromagnetic effects, along with some actual examples. Topics include:
- EME Virtual Prototyping Architecture
- Data exchange from the CAD systems to the EM simulation engines
- A detailed example of the import of a CAD system description into a simulation engine, developing an EM analysis model, and obtaining the desired results for an innovative avionics packaging concept
- A discussion of the existing state of the art, the present limitations in the VP process, where future R&D resources need to be applied.
