Pin ~ALTERA_DATA0~ assignment

Hello!

Currently I'm facing the folling error message (Stratix III, EP3SL70):

Error: Can't place multiple pins assigned to pin location Pin_N21 (IOPAD_X0_Y32_N62)

Info: Pin USB_DATA[0] is assigned to pin location Pin_N21 (IOPAD_X0_Y32_N62)

Info: Pin ~ALTERA_DATA0~ is assigned to pin location Pin_N21 (IOPAD_X0_Y32_N62)

Actually, I'm not aware of such a pin (~ALTERA_DATA0~) nor does it show up in the pin planner nor the assignment editor. I did not actively define such a pin. How can I prevent this incident?

Anybody got an idea?

Regards,

Peter

    The assignment is under Device and Pin Options / Dual purpose pins. Here you have to specify "Use as general I/O" for Data[0] and possibly other configuration pins.
