initial placement造句
例句與造句
- 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(guī)?;旌夏J讲季謫栴}為背景,提出了有效的初始詳細(xì)布局算法.在大規(guī)?;旌夏J讲季謫栴}中,由于受到計算復(fù)雜性的限制,有效的初始布局算法顯得非常重要.該算法采用網(wǎng)絡(luò)流方法來滿足行容量約束,采用線性布局策略解決單元重疊問題.同時,為解決大規(guī)模設(shè)計問題,整體上采用分治策略和簡化策略,有效地控制問題的規(guī)模,以時間開銷的少量增加換取線長的明顯改善.實驗結(jié)果表明該算法能夠取得比較好的效果,平均比paflo算法有16的線長改善,而cpu計算時間只有少量增加 - 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
