Abstract
Systems and techniques for pattern-based power-and-ground (PG) routing and via rule based via creation are described. A pattern for routing PG wires can be received. Next, an instantiation strategy may be received, wherein the instantiation strategy specifies an area of an integrated circuit (IC) design layout where PG wires based on the pattern are to be instantiated and specifies one or more net identifiers that are to be assigned to the instantiated PG wires. The PG wires can be instantiated in the IC design layout based on the pattern and the instantiation strategy. Additionally, a set of via rules can be received, wherein each via rule specifies a type of via that is to be instantiated at an intersection between two PG wires that are in two different metal layers. Next, one or more vias can be instantiated in the IC design layout based on the set of via rules.
