Designer can directly open designs created with previous versions of the Designer software.
If your design was created in version 3.1 or earlier, contact the Actel Technical Support department or go to http://www.actel.com/support for information on converting your design.
All existing die, package, pin assignments, and place-and-route information is read and maintained. Designs created in previous versions of the software may need library conversions when loaded into the Designer environment. If your design requires this conversion, Designer prompts you to allow the software to update the design to the new library before you attempt to start any of the Designer features.
