The present disclosure relates to a computer-implemented method for routing in an electronic circuit design. The method may include assigning a plurality of rats interconnecting one or more terminals associated with a layout of the electronic circuit design to a bundle. The method may further include sequencing the plurality of rats within the assigned bundle to generate a defined sequence of rats within the assigned bundle. The method may also include routing the plurality of rats between the one or more terminals, based upon, at least in part, the defined sequence.

System and method for electronic design routing between terminals

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.
