Abstract
A system and method for adjusting the shapes of polygons in a design. In some embodiments, the method includes inverting a first layer of the design, the first layer comprising one or more polygons, the inverting of the first layer forming a region complementary to the union of the polygons of the first layer, and including one or more inverse polygons. The method may further include performing a rounding operation on a first corner of a first inverse polygon of the one or more inverse polygons, to form a modified polygon.
Claims14
A method, comprising:
- inverting a first layer of an integrated circuit design, the first layer comprising one or more polygons, the inverting of the first layer forming a region complementary to a union of the polygons of the first layer, and comprising one or more inverse polygons;
- performing a rounding operation on a first corner of a first inverse polygon of the one or more inverse polygons, to form a modified polygon;
- and
- inverting the modified polygon to provide a modified first layer.
1 more element
A system comprising:
- a processing circuit;
- and
- a non-transitory computer-readable medium,
- the processing circuit being connected to the non-transitory computer-readable medium,
- the non-transitory computer-readable medium storing instructions that when executed cause the processing circuit to:
- invert a first layer of an integrated circuit design, the first layer comprising one or more polygons, the inverting of the first layer forming a region complementary to a union of the polygons of the first layer, and comprising one or more inverse polygons;
- perform a rounding operation on a first corner of a first inverse polygon of the one or more inverse polygons, to form a modified polygon;
- and
- inverting the modified polygon to provide a modified first layer.
6 more elements
A method, comprising:
- inverting a first layer of an integrated circuit design, the first layer comprising one or more polygons, the inverting of the first layer forming a region complementary to a union of the polygons of the first layer, and comprising one or more inverse polygons;
- and
- performing a rounding operation on a first corner of a first inverse polygon of the one or more inverse polygons, to form a modified polygon, wherein the rounding operation is performed by a sizing function.
