Abstract
In one embodiment, the invention is a method. The method is a method of routing a circuit having a set of nets and a set of circuit elements specified as a slicing tree and a set of linear constraints. The method includes finding short paths for the set of nets based on a minimum-spanning-tree solution to a floorplan derived from the slicing tree for each net of the set of nets. The method also includes routing the nets as conductors within channels of the floorplan, the conductors having locations satisfying a set of linear constraints based on the solution of a linear optimization problem.
