No board files for Cyclone II (EP2C20F484C7N)

Question

I recently got a hold of a Cyclone II (part number given in the subject). I installed Quartus II with all board files (including Cyclone II, III, and IV). When making a new project, I see board files for EP2C20F484C7, but not EP2C20F484C7N, so pin assignment does not work. I tried specifically reinstalling Cyclone II board files using the device installer, but Quartus recognized that I already had those files. How can I get the proper board files?

Hi,has been discussed quite often in the forum, just search for keyword "lead free".There's no functional difference indicated by "N" postfix except for lead-free package, it's the same chip and thus "N" isn't shown in the device selection. Just choose EP2C20F484C7.
