Unity 2009.1, from Pulsic, is the latest release of their physical chip design software suite. Unity 2009.1 features OpenAccess core support, common options format, and flow-routing bus routing option. With flow-routing, a bus will automatically route (flow) around obstacles by splitting and re-grouping. Tolerances can be set for obstacle size to optimise layout area. Unity increases productivity, decreases design area, and increases yield for even the most challenging custom digital, mixed-signal, and analog IC designs.
