Hi, I am trying to use the UCF found in the examples folder, but I have a problem with INST syntax. I am trying to figure out what exactly is suppose to be written in instance_name. I trying to modify the example to my design but I am always getting the same error when changing the path. ERROR:NgdBuild:753 - Line 272 in 'TOP.ucf': Could not find instance(s) 'pci_bridge32/pci_io_mux/ad_iob0/ad_out[0]' in the design. To suppress this error specify the correct instance name or remove the constraint. Any help with the INST syntax? What I should include in the path? Thanks Regards, Jorge _______________________________________________ http://www.opencores.org/mailman/listinfo/pci
