是否有一种简单的方法可以将一组约束与组件相关联

嗨，
检查SCOPED_TO_REF属性。
SCOPED_TO_REF：此属性采用模块（或实体）的名称。
约束仅应用于指定模块（或实体）的所有实例。
请参阅http://www.xilinx.com/support/documentation/sw_manuals/xilinx2014_2/ug903-vivado-using-constraints.pdf的第38页“约束范围”。
谢谢，
迪皮卡。

Hi,
 
Check SCOPED_TO_REF property.
 
SCOPED_TO_REF: This property takes the name of a module (or entity). The constraints are applied to ALL instances of the specified module (or entity) only.
 
Refer to page-38 "constraints scoping" of http://www.xilinx.com/support/documentation/sw_manuals/xilinx2014_2/ug903-vivado-using-constraints.pdf

嗨，正如你所提到的那样，数据跨越时钟域我几乎没有问题：1）时钟源和目标都是同步还是异步？2）你想分析路径还是想为此编写异常？
是否有一种简单的方法可以将一组约束与组件相关联，并让Vivado将它们应用于每个实例化？
- >如果您将约束从一个时钟域写入其他时钟域，它将影响每个路径。
谢谢，佳日



以下为原文

Hi,

As you mentioned data is crossing clock domains I have few questions:
1) Both clocks source and destination are synchronous or asynchronous?

2) You want to analyze the paths or you want to write exception for that?
 
 Is there an easy way to associate a set of constraints to the component and have Vivado apply them to every instantiation?
--> If you will write constraints from one clock domain to other it will affect for each and every path.

Thanks,
Yash

在Vivado中，应使用“启动时钟周期（或更快的时钟周期）来约束路径。

In Vivado, “launch clock period (or faster clock period) should be used to constraint the path.
