13.3 EDK, AXI_V6_DDRx - External Memory Model Simulations Fail when Using ECC

描述

When using the AXI_V6_DDRx core in ECC with the XPS-generated testbench, the memory does not complete calibration, as indicated by phy_init_done. How do I resolve this issue?

解决方案

This issue is caused by the uninitialized memory model returning X's during calibration. A possible workaround to this issue is to add the wire delay (wiredly.v) to the testbench, generated from a standalone CORE Generator MIG core generation. This module converts the 'X' signal to a valid logic value that the calibration logic can calibrate to.
