解釋
集成電路布圖設計-
Adopts vdsm process technology however two outstanding problems are faced to ic layout design when the feature size reaches to 0. 18 m or lower : 1. timing convergence problem seriously affects the circuits schedule, and the interconnect - delay has exceeded more than 70 % of the total circuits ’ delay. 2. si problem, usually it consists two aspects of ir - drop and crosstalk. these problems often affect the chip function after tapout
本篇論文就是針對超深亞微米階段soc晶元後端設計所面臨的挑戰，提出了運用連續收斂的布局布線策略，尤其是虛擬原型的設計理論，來快速驗證布局，進而提高布線的成功率，並且提出了一種改進的布局評估模型，提高對soc晶元預測布線的準確度;同時，對于時鐘驅動元件選擇，文中提出了一種基於正態分佈模型來達到更有效的選取。 -
