Abstract
Some embodiments of the invention provide novel methods for removing acute angles form routes in a design layout. The method reacts a route with several segments. It then identifies an acute angle between first and second contiguous segments of the route. The method next inserts a third segment between the first and second segments, where the third segment has an associated shape that fills the acute angle between the first and second segments.
