    If you're new to this I recommend you use the Pin Planner tool built into Quartus.

    If you haven't already, run the 'Analysis & Synthesis' on your project.

    Select 'Assignments' -> 'Pin Planner'.

    On the left will be a list of all your top level signal names. Double click the 'Location' cell next to each signal. This will allow you to assign the pin you want.

    Cheers,

    Alex

    In a similar vein, I am trying to understand what ends up in the Assignment Editor after a pin assignment. In my case, I'm using Quartus II 13.1 Web Edition with the DE0-Nano. In the Pin Planner, I assigned the 50MHz clock, resulting in the following:

    Node Name: CLK_50

    Direction: Input

    Location: PIN_R8

    In the Assignment Editor, this shows up as:

    Status: ? 'To' name unrecognized

    To: CLK_50 (with a question mark icon)

    Assignment Name: Location

    Value: PIN_R8

    Entity: (grayed out)

    However, there's another option in the Assignment Editor for "Assignment Name": external pin connection. In this case, I can enter the following:

    Status: Ok

    To: CLK_50

    Assignment Name: External Pin Connection

    Value: R8

    Entity: (my top-level entity name)

    So which is more correct? It certainly seems like the "External Pin Connection" would be the most accurate, but I cannot seem to find any documentation about when that should be used. And it doesn't quite seem to be associated to the Pin Planner. So now I am just confused.
