| 摘要: |
| 在超级计算机体系结构设计阶段，有必要进行时序规划，以尽早判断设计方案和性能指标的物理可实现性。提出一种性能驱动的时序规划方法，采用适于组件性能描述的时序性能模型，并按照线网权重分配路径延时余量，算法具有效率高、延时分配合理的优点。 |

| Abstract: |
| In the architecture design stage of super computer, it is indispensable to perform timing planning to judge the physical realizibility of architecture alternative and performance metrics as early as possible. This paper presents a performance-driven timing-planning method. A timing performance model which is suitable to describe component performance is adopted, and the path delay slack is distributed according to net weight. The algorithm has advantages of high efficiency and rational delay distribution. |
