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.
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.
