Integrated circuit routing based on enhanced topology

Abstract:

Aspects of the present disclosure address improved systems and methods for routing based on enhanced routing topologies. Consistent with some embodiments, the method may include accessing a routing topology of an integrated circuit design and determining that a routing path of a net in the routing topology violates a routing constraint. In response to determining that the routing path violates the routing constraint, a routing guide is created to reroute the routing path. The routing path in the net is then rerouted using the routing guide, thereby producing an enhanced routing topology that reduces issues in detailed routing caused by the routing constraint violation.
