Including XDC files hierarchically

Hi,

     Is it possible to include XDC files hierarchically, e.g. have a system_constr_top.xdc, which in turn includes the following additional xdc files:

system_constr_pinout.xdc

system_constr_clock.xdc

system_constr_impl.xdc

 

rather than configuring the relative orders via the constraint file properties?

 

Regards,

Hi

 

You can specify all the constraints in a single XDC file or in multiple XDC files and set the relative order.

 

Using a sigle XDC and specifying other XDC file types in this is not allowed.

 

Have a look at the below pdf for  the supported XDC flows
