Pblock Constraints in XCI IP

Hello,

I'm trying to package an IP, and the reuse it in a TCL based project, by instantiating it wit hteh create_ip command.

However, when creating the IP, I notice that the XDC files (especifically a pblock constraint) that are part of the IP are not included when the IP is created, even after I run either synth_ip or synth_design and open the resulting design.

So basically:

  1. How do I instantiate an IP with create_ip and retain the pblock constraints I have set on its top level?
  2. Can I set an xci file (instantiated IP) as a top level in the project I'm using it in?

Thanks

Hello,

What IP Packager flow are you using, packaging the IP from a project, BD, or directory? Are you using the wizard? I think one of two things is going on here:

1) You don't have the XDC constraints with the pblock set to USED_IN {SYNTHESIS, IMPLEMENTATION}

2) You don't have the XDC constraints with the pblock included in your packaged IP. Are other constraints applying besides pblock constraints?

 

Thanks,

Ryan
