QuartusII doesn't auto assign pins for CycloneV

Hi, I am new to the FPGA world and am currently using Quartus II 12.0. I am working with the Cyclone V device. I need the tool to auto assign the pins and i should be able to see the location...

If you don't specify which pins Quartus is to use it will assign them. You'll find them in the 'Fitter Location' column in the Pin Planner. If you can't see the column it may be off your screen to the right or not visible. If it's not visible, right-click on a column heading and add the Fitter Location column to the table.

The pinout is also captured in the .pin file. This will either be in your main project directory or, with newer version of Quartus, in the 'output_files' sub-directory.

If you're committing to a PCB based on this pinout, be sure to Back-annotate the pinout in your project, so it doesn't change after the next compile. Under the 'Assignments' menu, select 'Back-Annotate Assignements...'.

Cheers,
