I got this error when run the routing for my C++ code. 

There isn't enougth information to let me know which fucntion in my C++ code cause this issue.

Do I need to change the vivado optimization strategy and how in the xocc compiler?

 

Thanks.

Hi, @mathmaxsean ,

You can check whether the routed dcp is generated. 

If the the routed dcp exists, you can try to open_checkpoint of this routed dcp in Vivado GUI to get the further information.
