pin assignment for DE2 board

I need to assign pins for DE2 board. However, when I go to "assignments" in the toolbar, I couldn't find the "pin" selection. I couldn't bring out the pin assignment graph via assignment editor in the dropdown box of "assignments" either. I am using the newest web version of Quartus II. Could somebody please tell me how to solve this problem? Thanks in advance.

You're apparently asking for the Quartus Pin Planner, under Assignments.

For DE2 projects, the most convenient way is to copy all pin assignments (and top entity port definition) from an existing demonstration project.  

 

Pin re assignment can be basically made in the pin planner, but occasionally conflicting previous assignments might block it. In this case, I find it helpful to use the assignment editor that doesn't care for temporary conflicts.  

 

New pin assignments for a complete project can be best made by tcl scripts or writing to the *.qsf file.

If you look at this tutorial here: 

 

http://www.alterawiki.com/wiki/using_the_usb-blaster_as_an_sopc/qsys_avalon-mm_master_tutorial 

 

You will find that it has a DE2 pin assignments script written in Tcl. 

 

This thread here has a de2_basic.zip file that has the same script, but a much simpler design
