I/O assignment constraints are physical constraints for setting the pin location and I/O attributes for a specific architecture and device.
You can configure and assign input and output macros and their attributes to pins using the PinEditor tool in MultiView Navigator or by importing a constraint file.

Use PinEditor to manually place and configure your I/Os. There are two different versions of PinEditor. The version you use depends on which product family you are designing for:
For ProASIC3E, ProASIC3, ProASIC PLUS, Axcelerator, and ProASIC devices, use PinEditor in MultiView Navigator. To edit I/O attributes, use the I/O Attribute Editor tool.
For all other families, use the standalone version of PinEditor which has a built-in I/O attribute editor.
