Abstract: Embodiments relate to physically implementing an integrated circuit design while conforming to complex design rule constraints. According to some aspects, embodiments relate to an automated method for generating shapes for correcting design rule errors such as line end-to-end spacing violations. In these and other embodiments, the automated method determines the errors post-placement and automatically generates the required shapes, taking into account additional process design rules and neighboring shapes. Some embodiments consider clusters of objects, potential legal areas between line-ends, merging of potential legal areas and generation of various shapes to produce a design rule correct layout.

Abstract: A routing tool allows a user to create a set of routing templates, each specifying the shape of a routing corridor and identifying the corridor's terminal edges. Each routing template also specifies a set of constraints on routing of an unspecified number of conductors that are to be routed between the corridor's terminal edges. To direct the tool to create a routing plan for a particular set of conductors in a particular routing space, the user selects one of the routing templates and modifies the routing template if necessary to adjust the specified shape of the corridor to match that of the particular routing space or to adjust its specified routing constraints if necessary to accommodate any particular routing constraints to be imposed on that set of conductors. The routing tool then processes the modified routing template to generate the routing plan for routing the set of conductors between the terminal edges of the specified corridor in a manner that satisfies the specified routing constraints.
