Hi all,
I used planahead9.1.5 to facilitate partial
reconfiguration, and followed the guides. But after I exported
floorplan, there was no bus macro LOC constraint in the exported
top.ucf. So I had to add them manually. After I did so, during place&route, errors encountered:
Applying constraints in "top.ucf" to the design...
ERROR:NgdBuild:752 - Line 8 in 'top.ucf': Could not find instance(s)
'led_socket_0/led_socket_0/U4_R2L_BM' in the design.
Does anyone know how to solve the problem?
Thanks.
