Abstract : an algorithm is presented for better legal solution in detailed placement of large scale mixed macros and standard cells ic design. due to the limitation of computing complexity, an effective and efficient initial placement is very important for detailed placement. novelty of this algorithm lies in a better solution at initial stage by using network - flow method to satisfy row capacity constraint and the thought of linear placement problem ( lpp ) to resolve overlaps. moreover, divide - and - conquer strategy and other simplified methods are adopted to minimize complexity. experimental results show that the algorithm can get an average of 16 wire length improvement on paflo in reasonable cpu time
文摘:以大規模混合模式布局問題為背景，提出了有效的初始詳細布局演算法.在大規模混合模式布局問題中，由於受到計算復雜性的限制，有效的初始布局演算法顯得非常重要.該演算法採用網路流方法來滿足行容量約束，採用線性布局策略解決單元重疊問題.同時，為解決大規模設計問題，整體上採用分治策略和簡化策略，有效地控制問題的規模，以時間開銷的少量增加換取線長的明顯改善.實驗結果表明該演算法能夠取得比較好的效果，平均比paflo演算法有16的線長改善，而cpu計算時間只有少量增加 -
