DIFFERENTIABLE GLOBAL ROUTER

Abstract: mechanisms for generating metal routing guides in a circuit involve forming a plurality of directed acyclic graphs (dags) embodying routing trees for nets in the circuit, generating 2-pin subnets and 2-pin path candidates from the routing trees, and forming a dag forest from the routing trees, the 2-pin subnets, and the 2-pin path candidates.
