The present invention is directed to power routing with obstacles. A method for determining strap location for power routing in an integrated circuit may include receiving input parameters, the input parameters including a number N indicating a number of straps to be located, wherein a strap of the number of straps is denoted as i. An initial strap placement is found for 1 through N straps and strap placement is calculated by relocating a strap if an obstacle is encountered in an initial strap placement, the relocated strap utilized to relocate at least one other strap of the 1 through N straps. Strap placement may be calculated by employing a local gradient method, dynamic programming, and like methods as contemplated by a person of ordinary skill in the art without departing from the spirit and scope thereof.
