Xilinx XPS: use DIP Switch for select

Question

I'm trying to use a DIP-switches as select-signal in another module. So the DIP-switches are an external component.

I always get the following error: ERROR:NgdBuild:924 - bidirect pad net 'DIP_1_7<5>' is driving non-buffer primitives: ERROR:NgdBuild:924 - bidirect pad net 'DIP_1_7<6>' is driving non-buffer primitives: ERROR:Xflow - Program ngdbuild returned error code 2. Aborting flow execution... make: * [__xps/system_routed] Error 1

How can I use the DIP-switches in my XPS project? I don't want to use a Microblaze to read the values.

Answer 1

Ok, I solved the Problem by using IBUF primitives on the module inputs, where the DIP switches are connected.
