I am not sure about this but maybe someone could confirm.

I was also having problems trying to get the Arria V Hard Memory Interface to work. Everything built and compiled OK and the timing looked reasonable but on the actual board the DDR would not calibrate and start up. I tried reducing the clock speed [was 400MHz] down to something far less critical but still no luck.

Last September I was at a trade show where Altera had a booth so I went to see if anyone could help me. I was told that actually the HMI interface is not yet supported in Quartus for Arria V and wouldn't be until 12.2

We have had parts now for more than 1 year [ES] but still I am confused as to whether or not we can use this function especially as it APPEARS to work in QSYS..... so far I have had little response direct from Altera.
