Hello,I've met a strange problem while manipulating pin assignments in the "Pin Planner". Changing assignment of one port changes also assignment of another port to the same value (encircled by red line on the image below). Of course, the compilation fails. Any comments ? Thanks. http://www.alteraforum.com/forum/attachment.php?attachmentid=13116&stc=1
Nothing special ... just removed obsolete pins (after modifying ports in source code) that had nothing common with 2 pins, concerned by strange behavior.Ok, I could resolve the problem in "Assignment Editor", but the cause of such behavior remains misunderstood.
