15.5.3 Assigning pins in Package Pins View

I/O Attribute Editor (v6.2 and higher) includes a Package Pins view in addition to its Ports view. Click the Package Pins tab to display your I/O attributes by package pin number. This view makes it much easier to assign address/data ports to adjacent pins. Additionally, it enables you to assign VREF pins (which you cannot do in Ports view) and to sort on banks.
