No exact pin location assignment

[Altera_Forum]

I have made the following assignment in QSF using the pin assignment editor of Quartus-II. FPGA device is Stratix-V 5SGSMD4H1F35C1 

 set_location_assignment IOBANK_3A -to sink_N set_location_assignment IOBANK_3B -to sink_data set_location_assignment IOBANK_4B -to source_data set_location_assignment IOBANK_4A -to source_exp set_location_assignment IOBANK_7A -to source_N set_location_assignment IOBANK_3A -to source_ready set_location_assignment IOBANK_4B -to source_sop set_location_assignment IOBANK_4B -to source_valid set_location_assignment IOBANK_4B -to source_eop set_location_assignment IOBANK_3A -to sink_ready set_location_assignment IOBANK_3A -to sink_sop set_location_assignment IOBANK_3A -to sink_valid set_location_assignment IOBANK_8A -to Reset set_location_assignment IOBANK_8C -to Clock set_location_assignment IOBANK_3A -to sink_eop   Got warnings for all pins reporting " Pin --- not assigned to an exact location on the device" Some warnings are reported below.      Info (169086): Pin sink_data[0] not assigned to an exact location on the device  Info (169086): Pin sink_data[16] not assigned to an exact location on the device  Info (169086): Pin sink_ready not assigned to an exact location on the device  Info (169086): Pin source_N[0] not assigned to an exact location on the device  Info (169086): Pin source_N[1] not assigned to an exact location on the device  Info (169086): Pin source_N[2] not assigned to an exact location on the device  Info (169086): Pin source_N[3] not assigned to an exact location on the device  Info (169086): Pin source_N[4] not assigned to an exact location on the device  Info (169086): Pin source_N[5] not assigned to an exact location on the device  Info (169086): Pin source_N[6] not assigned to an exact location on the device  Info (169086): Pin source_N[7] not assigned to an exact location on the device  Info (169086): Pin source_N[8] not assigned to an exact location on the device  Info (169086): Pin source_N[9] not assigned to an exact location on the device  Info (169086): Pin source_N[10] not assigned to an exact location on the device  Info (169086): Pin source_N[11] not assigned to an exact location on the device  Info (169086): Pin source_data[0] not assigned to an exact location on the device  Info (169086): Pin source_data[1] not assigned to an exact location on the device  Info (169086): Pin source_data[2] not assigned to an exact location on the device  Info (169086): Pin source_data[3] not assigned to an exact location on the device  Info (169086): Pin source_data[4] not assigned to an exact location on the device  Info (169086): Pin source_data[5] not assigned to an exact location on the device  Info (169086): Pin source_data[6] not assigned to an exact location on the device  Info (169086): Pin source_data[7] not assigned to an exact location on the device   Could you please suggest how to clear the warnings and fix the issues?

every single data bit has to be be assigned to a specific pin, not just IOBANKS

The fitter has done this exact pin assignment itself inside the IOBANKS as this is an experiment and the FPGA has not connected to any board. If its to be done manually, how to do this in a simple way.

Well, like you have in the original post - these are only warnings saying you have not assigned pins - not errors. 

You could try assigning all outputs to virtual pins if this is only an experiment.

If you like what locations the Fitter has selected in the I/O banks, you can then back-annotate the locations it has selected to write exact locations to the .qsf file (Assignments menu).
