Abstract :
Phenomena of electromagnetic compatibility (EMC) have to be considered during layout synthesis of printed-circuit boards (PCBs), in order to design failsafe and high-performance systems. In this paper the PCB routing-system HERO, presented in a previous publication, is extended by a new layer-assignment/net-ordering phase, called midway routing, performed after global and before detailed routing. The new method yields a significantly increased completion rate, improved EMC-behavior, and fewer layer changes (vias) in about half the time of the previous version of HERO
