    Abstract: A method to place repeaters on existing structured routes based on user specified locations. Location can be specified in multiple ways. For example, a set of fixed repeating distances (starting from a driver), number of repeaters (spread evenly on net routing), an absolute cutline dissecting the existing nets routing (e.g., x or y coordinate measure from the origin of the cell), relative cutline dissecting the existing nets routing (e.g., x or y coordinate measured from the origin of the nets bounding box), etc. can specify location. A repeater legalization procedure allows a user to arrange repeaters in various forms thus legalizing them to meet specific design requirements. A preview mode is provided where results are presented in the form of annotations (e.g., cartoon drawings) displayed on a canvas (e.g., display screen) rather than in the form of real layout objects in a database.

    Abstract: The computer executable instructions include a command that accepts multiple user input through various command options. The command encapsulates and implements multiple original software algorithms that convert trunking design intent, expressed via the command options, into trunks on multiple layers of a process technology node. Once executed, the command generates shapes of trunks of specified topology on specified layers. The command includes a set of options to generate a simple or complex trunking topology. The command accepts topology, set of zones, nets and many other options that the user provides to the command to yield trunks of a desired topology. The topology description is relative; thus, it can easily adjust as design changes. The command together with its options represents trunk creation intent.
