Abstract
We consider the problem of wiring planar knock-knee mode layouts. We present a systematic approach to this problem and develop a unified framework that also applies to layouts using grids that are more general than the usual square grid, and determine all possible grids that satisfy some natural regularity criteria. We develop some specific techniques for wiring of layouts in the square grid. As one of the applications of these techniques, we give a simple characterization of two-layer wirability of an arbitrary layout.
