2.3.4. Configuration when using ECC

This section describes how to configure an EMIF design to use ECC. For ECC selection, you need to:

  1. Click Dive Into Packaged Subsystem in the External Memory Interfaces for HPS window.

  3. Change the EMIF IP parameters to suit your requirements. To enable ECC for DDR4/DDR5, select ECC DQ Width to 8, for example. In the case of enabling In-Line ECC for LPDDR4/LPDDR5, select Use In-Line ECC.
  4. Save and exit the Dive Into Packaged Subsystem window.
