多周期路径是将复杂电路运算拆分在多个时钟周期完成，从而提高电路总体运行频率的一种设计方法，是数字电路中广泛使用的一种设计手段。实践中多周期路径的设计、约束与实现经常误用导致设计迭代和反复。文中结合在研项目，对多周期路径的产生机理进行了系统的分析，针对设计中常见的问题展开分析，提出了一种多周期路径的设计实现和施加约束的方法。实践结果表明，采用文中提供的方法可以有效避免多周期路径的误用，减少设计迭代，提高设计效率。

Multi-cycle path is the data path which needs multiple clock cycle to complete computation in the circuit. Multi-cycle path is widely used in digital integrated circuit design to improve the operating frequency of the circuit. However,it is frequently found design it-eration as the result of multi-cycle path being misused in design practice. By the research and analysis of multi-cycle path in IC design and problems often found during design process,a way of multi-cycle path implementing and constraint is presented. The result shows that this method avoids the misuse of multi-cycle path efficiently,improves design efficiency and shortens the whole design process.
