Abstract: A technique will automatically route interconnect of an integrated circuit while taking into consideration current density rules. In an implementation, the technique uses a shape-based approach where a grid is not used. Based on data input including current density and a frequency of each net, the technique will determine the current requirements for each net. In an implementation, the technique forms a Steiner tree for a net, and routs using the Steiner tree. The technique widens nets having greater current requirements; adjacent wiring may be pushed aside to create sufficient space for wider nets.

Abstract: A system of automatically routing interconnect of a integrated circuit design while taking into consideration the parasitic issues of the wiring as it is created. The system will be able to select an appropriate wiring pattern so that signals meet their performance requirements.

Abstract: A technique will automatically route interconnect of an integrated circuit and adjust spacing between tracks or interconnect in order to improve performance or reduce electromigration effects. By increasing spacing between certain tracks or moving tracks, performance can improve because a track will be more noise immunity from nearby tracks on the same layer or on different layers. The automatic router will adjust spacing between tracks depending on one or more factors. These factors may include current associated with a track, width of a track, capacitance, inductance, and electromigration. In a specific implementation, the technique uses a shape-based approach where a grid is not used. The technique may further vary the width of the tracks.

Abstract: A method and technique of routing interconnects of an integrated circuit providing improved routing quality. In an embodiment of the invention, the technique provides linear spine interconnect routing. In memory array blocks, such as in DRAM and SRAM memory designs, connected pins are generally separated by large distances in a first direction and small distances in a second direction, or a spine or channel region. A route area is defined within the spine region. In one embodiment, obstacles in the route area are identified and corresponding forbidden areas are demarcated. The linear spine interconnect is routed in the first direction within the route area while avoiding the forbidden areas. Pins are connected to the spine interconnect by stitching interconnects. Stitching interconnects are generally routed in the second direction.

Abstract: A system and technique to specifies patterns to search for in an integrated circuit layout, and specifies proposed replacement patterns. A description file includes specifications for one or more patterns to be searched for. In the description file, for each pattern, there may be one or more proposed replacement patterns. The description file is read. Pattern matches, if any, in a layout are found. A proposed replacement pattern is tested in place of a matched pattern. If acceptable, the proposed pattern may be used to replace the matched pattern.

Abstract: An iterative technique is used to automatically route nets and alter spacing of an integrated circuit design to achieve a fully routed and compact result. After identifying cells rows and channel, which are gaps between the rows, the technique determines which nets should be routed in which areas. Spine routing is used for nets than span more than one row or channel. Alter the space between rows, larger or smaller, which will allow routing of the nets.
