5. Possible modifications to the constraints

Naturally, any modification made during the design cycle can have an impact on the EMC of the complete system, whether in terms of structure, wiring or electronics (equipment). Managing these modifications is essential to guarantee the proper functioning of the overall solution.

There are two major types of modifications to be made to simulation models. The first type is linked to the progress of the project, which gradually makes the models more complex. The second is normally linked to the need to resolve a doubt on a particular point that has been raised, usually at a late stage.

Thus, the transition from the preliminary design phase to the detailed design phase requires a progressive refinement of models (figure 11 ). During the engineering...
