Abstract
Techniques that can improve the efficiency of routing where connections are subject to elongation constraints. The design can be optimized by estimating elongation needed to meet constraints after an initial routing solution has been generated, but before elongation is actually applied to detailed paths. Paths can be re-routed at this earlier stage if it is determined that too much elongation, or too much elongation in crowded areas, will need to be added after the detail routing stage.
