在.xdc文件中进行任何更改时，进程是从综合开始的

你好@ shweta_agnihotri
如果修改的约束是不影响合成结果的物理约束，则可以强制合成运行为最新。
约束更改后，您可以在TCL控制台中使用以下命令
set_property NEEDS_REFRESH FALSE [get_runs synth_1]
上述命令将强制合成运行为最新。

Hi @shweta_agnihotri
 
You can force synthesis run up-to-date if the constraints modified are physical constraints which does not effect synthesis results. You can use below command in TCL console after constraint changes
 
set_property NEEDS_REFRESH FALSE [get_runs synth_1]
 
The above command will force synthesis run up-to-date.
Thanks,
Deepika.

嗨@ shweta_agnihotri，
你可以做两种方式：
作为@ vemuladtold，您可以更新力量
否则，您可以创建单独的约束文件，并仅在实现中使用它，而不是在综合中。

Hi @shweta_agnihotri,
 
You can do 2 ways:

• As @vemulad told you can go for force up to date
  
• Else you can create a separate constraints file and use it in implementation only not in synthesis.
  

Thanks,
Arpan
