Abstract : a cad tool based on a group of efficient algorithms to verify, design, and optimize power / ground networks for standard cell model is presented. nonlinear programming techniques, branch and bound algorithms and incomplete cholesky decomposition conjugate gradient method ( iccg ) are the three main parts of our work. users can choose nonlinear programming method or branch and bound algorithm to satisfy their different requirements of precision and speed. the experimental results prove that the algorithms can run very fast with lower wiring resources consumption. as a result, the cad tool based on these algorithms is able to cope with large - scale circuits
文摘:介紹了一個基於標準單元布圖模式的電源線/地線網路的輔助設計集成工具.它應用了一系列高效的演算法，為用戶提供了電源線/地線網路的設計、優化和驗證的功能.非線性優化技術、分枝定界演算法和不完全喬萊斯基分解的預優共軛梯度法是該工作的三個主體部分.用戶可以選擇使用非線性規劃的方法或者幾種分枝定界方法來滿足他們對于精度和速度方面的不同需求.實驗結果表明，文中所提供的演算法可以在很快的運行速度下實現更低的布線資源佔用.因此，在這些有效演算法基礎上實現的輔助設計工具具有處理大規模電路的能力 -
