Max10 speedgrade 8 and DDR2 memory

[Altera_Forum]

Hi, 

 The MegaWizard tells me that Max10 speedgrade 8 devices are not supported for DDR2 memory interface generation in general. I've now targeted a speedgrade 7 device and created the RAM interface successfully (at least I think so as TimeQuest reports OK and I have no hardware available yet to test it in reality).  If I then switch back my design to a speedgrade 8 device and recompile it using the previously generated memory interface, TimeQuest still reports positive slack.  So, for now I have two tools reporting two different results.  Is TimeQuest currently not testing properly? Is the MegaWizard as well as the online memory selector guessing too pessimistic as the result (speedgrade 8 not supported) does not depend on clock frequency and RAM delay settings? Or what did I do wrong?  Best regards, tfranke

Even the -8 device able to close timing in timequest, but it do not have any functionality validation on on actual hardware, so we cannot claim it is supported.  

I will suggest we refer to EMIF estimator for clearer support scheme.  https://www.altera.com/products/intellectual-property/best-in-class-ip/external-memory/support-selector.html# Apparently, -8 for Max 10 do not support DDR2.  (This message was posted on behalf of Intel Corporation)
