Design rules in advanced IC manufacturing processes are increasingly problematic for modern router architectures and algorithms. This paper first reviews types and causes of “difficult” design rules, as well as implications for current routing approaches. Next, some basic router components are assessed with respect to future viability. Last, the paper discusses prospects for future “coevolution” of design rules and detailed routing methods.
