Abstract:
1. A method of designing an integrated circuit (“IC”) layout, the IC layout comprising a plurality of layers, the IC layout comprising a plurality of nets, each net comprising a plurality of routable elements, the method comprising: using a computer for: identifying a particular net as a net to be shielded, said particular net having a set of associated route segments that connect the routable elements of the particular net; and defining shield segments adjacent to at least one of the route segments associated with the particular net, wherein at least one of the shield segments is oriented diagonally with respect to a boundary of the IC layout, at least one particular layer having a preferred routing direction, a particular shield segment on the particular layer of the IC layout having a direction that is different than the preferred routing direction of the particular layer, each shield segment representative of an IC shield segment formed by a conductive material that connects to a particular power state, wherein the conductive material shields a first wire segment on an IC from forming an electrical connection with a second wire segment on the IC, said first and second wire segments are based on first and second route segments.
