提出了一个在多约束下进行性能优化的总体布线算法 .研究了在总体布线阶段同时进行 RL C耦合噪声 (串扰 )、时延性能和布线拥挤优化的问题 .根据所提出的算法思想已实现了相应的总体布线器 :CEE- Gr.并对所实现的总体布线器 CEE- Gr进行了 MCNC电路例子的测试 ,得到令人满意的结果 .
An overall routing algorithm for performance optimization under multiple constraints is proposed.The problem of simultaneous RL C coupling noise (crosstalk), delay performance and routing congestion optimization in the overall routing stage is studied.According to the proposed algorithm, The corresponding overall router: CEE-Gr. And the implementation of the overall router CEE-Gr MCNC circuit example of the test, get satisfactory results.
