Device Family: Intel® MAX® 10

Intel Software: Quartus Prime Lite, Quartus Prime Standard

Type: Errata

Area: EMIF


IP: DDR2 SDRAM Controller with UniPHY

Why doesn’t the Intel® MAX® 10 DDR2 mem_odt signal toggle during calibration in both the RTL simulation and in hardware operation?

Description

Due to a problem with the Intel® MAX® 10 DDR2 IP, the mem_odt signal doesn’t toggle during calibration. Although this is incorrect behavior for the mem_odt signal during calibration, there is no functional impact to the DDR2 interface.

After calibration, the mem_odt signal toggles as expected during memory write transactions.

Workaround/Fix

 

This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Software.
