i.MX8 Nano DDR Tool Test Results – Acceptance Confirmation

Hi,

Below are our DDR validation results from the DDR Tool. Could you please review them and let us know whether the results are acceptable? If not, could you please suggest possible ways to improve the results?

Re: i.MX8 Nano DDR Tool Test Results – Acceptance Confirmation

Hello,

The report looks in general good, the functional tests pass and the subsequent Data and CA vTSA tests pass. for more information:

DDR Tool — Config Tools for i.MX Applications Processors 26.06 documentation

to improve the result:

Select ODT/driver values toward the middle of the passing region, rather than using values adjacent to failed combinations.
If margins remain a concern, review DDR PCB signal integrity, particularly impedance, routing, termination, and signal integrity around DQ/DQS and CA.
Re-run validation across the intended operating conditions and hardware population rather than relying on a single board/result.
Keep in mind the DDR Tool is an evaluation/debug/optimization aid and that its results cannot substitute for traditional validation and compliance testing required to establish JEDEC compliance.
