In a method of routing a wire to a shape in an integrated circuit for minimizing undesirable jog creation during a masking process, a plurality of possible placements of the wire relative to a selected edge of the shape resulting in the wire being connected to the shape are determined. A cost is assigned to each placement, the cost indicating an amount of jog that would be created in the masking process corresponding to the placement, wherein a greater cost indicates that a greater jog would be created in the masking process than would be created by a placement assigned a lesser cost. A placement having a lowest cost of the plurality of possible placements is selected.

Auto-routing small jog eliminator

A method for automatic wire size modification comprising the steps of routing a wire to a source; detecting a first size differential between the wire and the source by calculating a width difference between a width of the wire and a width of the source, and dividing the width difference by the width of the wire; and modifying a size of the wire if the first size differential is less than a maximum width percentage and if a length of the source is less than a length range specified by a user.

System and method for auto-routing jog elimination

A method for automatic wire size modification comprising the steps of routing a wire to a source; detecting a first size differential between the wire and the source by calculating a first width difference between a length of the wire and a width of the source, and dividing the first width difference by the width of the source; detecting a second size differential between the wire and the source if the first size differential is less than a maximum length percentage by calculating a second width difference between the width of the source and a width of the wire, and dividing the second width difference by the width of the source; and modifying a size of the wire if the second size differential is less than a maximum width percentage.
