Congestion is one of the fundamental issues in very large scale integration physical design. In this paper, we propose two congestion-estimation approaches for early placement stages. First, we theoretically analyze the peak-congestion value of the design and experimentally validate the estimation approach. Second, we estimate regional congestion at the early stages of top-down placement. This is done by combining the wire-length distribution model and interregion wire estimation. Both… Expand
