Pin-out configuration

I receive this error messgae :

[Vivado 12-1411] Cannot set LOC property of ports, Could not legally place instance vauxp0_IBUF_inst at E15 (IOB_X0Y130) since it belongs to a shape containing instance vp_in_IBUF_inst. The shape requires relative placement between vauxp0_IBUF_inst and vp_in_IBUF_inst that can not be honoured because it would result in an invalid location for vp_in_IBUF_inst. 

I don't understand the root-cause for this problem

Please assist

which device is this? What package

It seems just from reading the error that you are using the XADC and are trying to LOC the dedicated VP/VN input to the XADC and the VAUX0 auxillary analog input to invalid inputs. 

there should be no need to specify a location of the VP/VN it's a dedicated pin. 

Vaux IO are pretty much assigned to a fixed IO in a bank that can vary depending on the device and package you are in. The only thing you need to do is set it to an IO standard that compatible with the VCCO in the bank. (this is not really necessary it just gets it through the tools)
