Question about warning in Quartus II

I have done FPGA and CPLD design before, but i have never seen this error and am not sure if it is something i need to worry about or if it is a setting i need to change...im sure someone can tell me quickly. 

 

Warning: Ignored locations or region assignments to the following nodes 

Warning: Node "TCK" is assigned to location or region, but does not exist in design 

Warning: Node "TDI" is assigned to location or region, but does not exist in design 

Warning: Node "TDO" is assigned to location or region, but does not exist in design 

Warning: Node "TMS" is assigned to location or region, but does not exist in design 

 

 

Obviously, these are the JTAG signals, i assigned them in the pin planner, which is all i thought i would have to do. 

 

Is there something else i need to set in the software to get rid of these warnings? 

 

Thanks, 

 

Dan

You don't need to assign these dedicated pins. You need to wire them in hardware but not in vhdl

they are wired in hardware, are you saying i dont need to assign them on the pin planner?

You don't need. The reason is simple; they are not used in your design modules to drive or be driven. They are meant for internal JTAG circuitry and altera knows them and already connected them internally.

many thanks 

 

i cant seem to remove the pin assignment, but i will know the warning is meaningless.

You can always just delete the assignments from the QSF file using any test editor.
