Modgen Topology Constraints

---

The Modgen pin-to-trunk router recognizes topology objects and their constraints and creates geometries that match the topology pattern. You can add topology constraints to customize certain routing attributes. All topology constraints have a name, a layer, and a value. The layer can be set to nil if it is not applicable.

The Modgen topology constraints can be passed as arguments to certain Modgen place and route SKILL APIs such as gpeCreateTrunkEntries, gpeCreateTwigEntries, and gpeCreateStrapEntries. These constraints are honored while creating the respective topology objects.

In the following example, values for twigConstraints are first instantiated. These values are then passed as an argument to gpeCreateTwigEntries.
