AM6442: IBIS model verification

Fhamitha M

Part Number: AM6442

Tool/software:

Hi,

In the AM6442 processor IBIS model, certain pins such as E1 and F1 (clock), E2, T8 (address), and other DDR-related signals, which are expected to be outputs in the actual schematic, are incorrectly marked as inputs in the IBIS model. We observed this issue while checking both IBIS models — SPRM810 and SPRM730E. Can we confirm if an updated or corrected IBIS model is available for accurate signal integrity analysis?

Hello Fhamitha,

Please refer inputs i received:

Can they pinpoint the line number where they think the issue is? I’m not seeing it. Maybe they are choosing the wrong model for the clock and address signals.

Can you recheck.

We have customer using the model and not recived similar complaints.

What tool do you use?
