3.4.4.2. Implementing a x72 Interface with Hard Memory Controller

The following diagram illustrates one possible implementation of a DDR3 or DDR4 x72 interface using the hard memory controller.

Note that only the hard memory controller in the address and command bank is used. Similarly, only the clock phase alignment block of the address and command bank is used to generate clock signals for the FPGA core.

In the above diagram, shaded cells indicate resources that are in use.

Note: For information on the I/O lanes and pins in use, consult the pin table for your device or the <variation_name>/altera_emif_arch_nf_140/<synth|sim>/<variation_name>_altera_emif_arch_nf_140_<unique ID>_readme.txt file generated with your IP.
