Quartus warned that altdpram does not support Cyclone families. And this core didn't work. I wanna know why this core didn't work? Because I should change another Chip of altera? Or could I do some fix job, to work it out ? I'm not speaking English. So maybe my expression looks strange. Waiting for answers, and thank you very much.   by nios man on 12-Oct-2008 Ed, do you use this core in a "real world". I'm looking for a CAN IP. Does this core is stable ? Please help. Regards.   by Ed Henciak on 18-Jul-2008 This solution solved a problem we were seeing....it really should be added to the design if at all possible!!!   Add your comment Your email: Retype key:
