The present invention introduces several methods for implementing arbitrary angle wiring layers for integrated circuit manufacture with simulated Euclidean wiring. Entire routing layers may be implemented with arbitrary angle preferred wiring using simulated Euclidean wiring. In a first embodiment, the...http://www.google.com/patents/US6915500?utm_source=gb-gplus-sharePatent US6915500 - Method and arrangement for layout and manufacture of nonmanhattan semiconductor integrated circuit using simulated Euclidean wiring
