FARM: an efficient feed-through pin assignment algorithm

Abstract

The authors propose an efficient feedthrough pin assignment algorithm, FARM, to minimize the maximum channel density, and at the same time to reduce the wire length and via number. A novel vertical channel routing formulation is devised to model the pin assignment problem. A multirow density minimization followed with a single-row pin assignment is proposed to complete the assignment process. Some experimental results and a comparison with previous work are given.<>
