Memory address at which the burst should start. The width of this bus is sized
using the following equation:
For one chip select:
width = bank bits + row bits + column bits – 2
For multiple chip selects:
width = chip bits + bank bits + row bits + column bits – 2
If the bank address is 3 bits wide, row is 14 bits wide and column is 10 bits
wide, then the local address is 25 bits wide. To map local_address to bank,
row and column address:
local_address is 25 bits wide
local_address[24:22] = bank address [2:0]
local_address[21:8] = row address [13:0]
local_address [7:0] = col_address[9:2]
The two least significant bits (LSB) of the column address on the memory side
are ignored, because the local data width is four times that of the memory data
bus width.
Byte enable signal, which you use to mask off individual bytes during writes.
local_be is active high; mem_dm is active low.
To map local_wdata and local_be to mem_dq and mem_dm, consider a
full-rate design with 32-bit local_wdata and 16-bit mem_dq.
Local_wdata = < 22334455 >< 667788AA >< BBCCDDEE >
Local_be
These values map to:
Mem_dq = <4455><2233><88AA><6677><DDEE><BBCC>
Mem_dm = <1 1 ><0 0 ><0 1 ><1 0 ><0 1 ><0 1 >

shows the DDR3 SDRAM HPC local interface signals.
ALTMEMPHY signal that specifies the serial termination value. Should
be connected to the ALT_OCT megafunction output
seriesterminationcontrol.
ALTMEMPHY signal that specifies the parallel termination value.
Should be connected to the ALT_OCT megafunction output
parallelterminationcontrol.
Allows the use of DLL in another ALTMEMPHY instance in this
ALTMEMPHY instance. Connect the export port on the ALTMEMPHY
instance with a DLL to the import port on the other ALTMEMPHY
instance.
