Title: AN EASY PLANARITY TEST FOR UNFLIPPABLE MODULES.
Authors: S. Zaks
PDFCS0771.pdf
Abstract:

Given a set of VLSI modules, with labeled terminals on each, and such that each terminal appears in exactly two modules, we present a simple, linear-time test for determining whether this set of modules has a planar embedding, in which terminals with equal labels are connected without crossovers, and where it is not allowed to flip the modules. By using a property of oriented polyhedrons, our algorithm is very simple, and much simplifies previous algorithms for this problem.
