Zusammenfassung:	A mechanism is provided for the user to define a circuit design intent or strategy in the form of data that is stored with the design database. An autorouter then uses this guidance from the user to create a plan for routing the design. The user can then modify their guidance to the router until the results for the plan are acceptable. Using the planned flow, the autorouter can complete the design, creating detailed paths including etch segments and vias. Allowing such interaction with an autorouter significantly reduces the routing time and hence time-to-market.
