Connecting Memory to the PHY Interface
The PHY interface permits connections to 8-, 16-, 32-, and 64-bit SDRAM, DDR, or DDR2 memories on
Spartan-3/Virtex-4/Virtex-5 FPGAs. The PHY interface permits connections to 8-,16-, and 32-bit DDR2 or DDR3 on
Virtex-6 FPGAs.
Table 59 lists the unique signals and parameters for each available PHY layer (excluding standard memory and
clock signals).
