A linear wirelength objective more e ectively captures timing, congestion, and other global placement considerations than a squared wirelength objective. The GORDIAN-L cell placement tool 16 minimizes linear wirelength by rst approximating the linear wirelength objective b y a modi ed squared wirelength objective, then executing the following loop 1 minimize the current objective to yield some approximate solution, and 2 use the resulting solution to construct a more accurate objective u n til
