Abstract : a new algorithm w - ecop is presented to effect incremental changes on a standard cell layout automatically. this algorithm deals with cell inserting and cell moving based on rows instead of on cells as most placement algorithms usually do. an integer programming problem is formulated to minimize the adjustment on the initial placement and a heuristic method is presented to search for a shifting path so as to optimize the wirelength. test of w - ecop on a group of practical test cases shows that the algorithm can successfully accomplish incremental placement with good quality and high speed
