Design build failure of VC707 board example design

General - GRLIB SoC

I ran make vivado and it got to this point of running the DRC task and it failed. Something about black box for some contents. Anyone able to successfully build this example design?

Hello Salman,
I believe the GRFPU IP is not available in GPL releases. You can disable it using “make xconfig” or editing the vhdl file config.vhd.

The list of the IPs available in GPL is in section 1.4 of grip.pdf .

Hope this helps!

That explains it…okay. I will have to either remove it or find another example design version without non-GPL IP.
