Microsoft Word - Switchbox.doc Mathematical Problems of Computer Science 26, 2006, 5 – 8. 5 On Switchbox Routing Algorithm Vardan A. Manukyan Institute for Informatics and Automation Problems of NAS of RA e-mail vardanm2003@yahoo.com Abstract We present new switchbox routing algorithm that consider the characteristic of net crossings. The routing strategy is based on parallel bubble sorting technique. Non-Manhattan wires as well as overlapping wires are introduced. Preliminary results show that a class of switchbox routing problems can be routed by using smaller overall interconnection length than the Manhattan models provide.
