Hi,
I have downloaded the IBIS model for DP83867IRRGZ from below link
https://www.ti.com/product/DP83867IR#design-tools-simulation
DP83867IR IBIS Model (Rev. A) SNLM191A.ZIP (80 KB) - IBIS Model
But for the SI analysis we couldn't to able to achieve the rise and fall time for TX signals
Zero transmission itself monotonic failure is observed
Please provide if any alternate model for LVCMOS I/O or additional drive strength available for the PHY
Regards,
Parthan
