I instantiated the same altsyncram component in a blank design and Quartus processes it perfectly without errors.
Could it be a conflict with the sopc builder system I have in the original target design?
Infact I see that sopc builder auto generates other altsyncram*.tdf file in the \db directory. I checked them and they all seem similar to the one generated for my altsyncram.
I changed a few parameters in Wizard int order my altsyncram exactly matches one of those sopc files (apart the name...) but I always get the same error.
Please, any help is greatly appreciated because I've been stuck on this point for two days so far.
