Hi all.
My question is about the interface of SATA/SAS. I use megafunction Stratix V Transceiver Native PHY. I understand that the bus tx_parallel_data[63..0] is used as data bus and the utility bus signals. But unfortunately, I can't understand how divided the address space on the external drive. For example: I want to record 32-bit word at some address 0x10. What should I record in this case, on the bus tx_parallel_data[63..0]?:confused: Can anyone explain the principle of exchange of information with the external drive? Or give an example? I was looking at the V-Series Transceiver PHY IP Core User Guide, but the answer to my question is not found (https://www.altera.com/en_us/pdfs/literature/ug/xcvr_user_guide.pdf). Thank you in advance. Regards, Andrey.Link Copied

If I understand right, you are asking about SATA protocol. That's beyond physical layer transceiver specifications. "Serial ATA Revision 3.0" is the present standard.

I have the same question, can anyone suggest one application note, if it exists, or something similar can help to design Sata protocol?

FvM,
But if you look on megafunction. How to write data to avalon bus? Do I need to write control words on bus avalon?- Mark as New

If I understand correctly, it is a communications Protocol that SATA. Here is written at a low level bytes of instructions and data bytes.
