Honored ContributorThe user guide from Altera is bad !
Who can teach me how to use the following inputs? local_address local_be local_burstbegin local_read_req local_write_req local_size local_wdata Who can show me a simple example that just write some data into the DDR2 and then read? The so-called user guide has just a lot of definitions, but no detailed examples!!! Thanks in advance!!!
Honored ContributorWhy not to use SOPC/QSys and take out only Avalon-MM signals?
Honored Contributorthanks, but I don't know anything about SOPC/QSYS, and I don't want to get more confused.....
Honored ContributorWell, the Avalon-MM bus is way much easier to work with, so I think it'd be better for You to check it out :)
Or if You really really don't want to use Avalon-MM, then download Avalon-MM memory master read/write examples. Those signals in Avalon-MM are probably the same as exported from the core generated by megawizard.Honored ContributorThanks again, but I really want someone can teach me how to use the high performance controller II directly.......
Honored Contributordid you take a look at the timing diagrams?
http://www.altera.com/literature/hb/external-memory/emi_altmemphy_ref_timing_diagram.pdfHonored Contributoryes, I do look at the timing diagrams, but those diagrams are too "theoretical", I cannot produce the same diagrams in my quartus II.................
Honored ContributorIn addition, those timing diagrams are separate read or write operation, if you write and then read the same DDR2, the timing is a different story....
Honored Contributorrun the example top simulation?
Honored Contributorokay, I will run the example and try to learn something from it..... does it really help the understanding?
