Abstract
Due to the increasing significance of fast component technologies and the increasing complexity of printed circuit boards, electromagnetic phenomena, e.g. reflections and cross-talk, gain more and more importance and may even disturb the function of a printed circuit board. In the future, it will be indispensable to consider phenomena of electromagnetic compatibility (EMC) already during layout synthesis. In this paper robust methods are presented which, for the first time, make it possible to incorporate complex EMC-constraints and EMC-cost criteria into printed circuit board routing. The results achieved so far are reported.
