Totally confused by the DDR2 high performance controller II

[Altera_Forum]

The 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!!!

Why not to use SOPC/QSys and take out only Avalon-MM signals?

[Altera_Forum]

thanks, but I don't know anything about SOPC/QSYS, and I don't want to get more confused.....

[Altera_Forum]

Well, 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.

Thanks again, but I really want someone can teach me how to use the high performance controller II directly.......

[Altera_Forum]

did you take a look at the timing diagrams?

[Altera_Forum]

yes, I do look at the timing diagrams, but those diagrams are too "theoretical", I cannot produce the same diagrams in my quartus II.................

[Altera_Forum]

In 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....

run the example top simulation?

[Altera_Forum]

okay, I will run the example and try to learn something from it..... does it really help the understanding?

I also have a question about avalon-mm port of DDR2 HPC-II. 

 What are settings for the following interface properties: 1. burstOnBurstBoundariesOnly  2. linewrapBursts  I didn't find answers in Altera's External Memory Interface Handbook nor in the wiki mentioned in the post above.
