Hi,

For your information, regarding your previous note on the MIF info mapping, in the reduced MIF, the 6 MSBits of the MIF data = reconfig address while other LSBits = reconfig data. The MIF file is generally stored inside a ROM. You may then connect the 22 bits output of the ROM according to the port mapping mentioned to reconfig_address and reconfig_data at top level.

Thank you.

Hi,

From AN-635-1.1, understood that there are 2 methods for interfacing SSD with Stratix IV by SATA Protocol.

  1. Re-configuring only the transmitter datapath data rate (Data rate division in TX).
    1. In this no .mif generation required. Right ?
    2. By this method, can we read back from SSD also ?
  2. Re-configuring the TX and RX CDR PLL across SATA data rates
    1. .mif genetation required. Right ?
