Critical Issue
In the ALTGX MegaWizard Plug-In Manager, if on page 2a you set Which device family will you be using? to any family other than Stratix II GX, and then on page 3 you turn off Match project/default, and set Currently selected device family to Stratix II GX, the MegaWizard Plug-In Manager becomes unresponsive.
If the MegaWizard Plug-In Manager is unresponsive, close it and start again.If you want to change the device family your ALTGX megafunction targets, change Which device family will you be using? on page 2a.
