17 years agoI had nearly the same problem and the reason was that quartus optimized away my megafunction component because i didn't connect the outputs of the ALT2GXB megafunction to logic and bcause of that my gxb pins weren't connect to a gxb-transceiver.
So i just declared outputs in top level for testing purposes and connected them and then it worked. Maybe that's the reason. Dave
