DP83867CS: Using the IBIS-AMI model in the SI analysis of SGMII

Hello experts,

I am trying to use the IBIS-AMI model for TX or RX.
So I downloaded the IBIS-AMI model from the product page of "DP83867CSRGZR".

www.ti.com/.../snlm211

Should I use "DP83867_TX.ibs" or "Tx.ibs"?

Download list
- DP83867_RX1.ibs
- DP83867_TX.ibs
- Rx1.ibs
- Tx.ibs

Thanks and best regards,

Shinigo Ozaki
