DP83867CS: Analysis of SGMII differential lines using IBIS model

Shingo Ozaki

Part Number: DP83867CS

Hello experts,

I would like to perform an SI analysis of "DP83867CSRGZR" in SGMII.
I have downloaded the IBIS model from the product page of "DP83867CSRGZR".

However, the IBIS model does not have a differential line for SGMII, so ADS defines it as a single-ended line as shown in the figure below.
Is there any problem with SI analysis of the SGMII differential line?

Figure1 FPGA_TX_DP83867_RX

In addition, the SGMII differential output pins in the IBIS model do not have the word "SGMII" on them.

Is the pin configuration correct as shown in the figure below?

Thanks and best regards,

Hi Shinigo,

This link will download the 867 SGMII Ibis Model. In the zipped folder there is a User's Guide on how to use.

Hello Alvaro-san,

Thank you for your response.

We want to do SI analysis using IBIS model not IBIS-AMI model.
Because the FPGA opposite of DP83867 is IBIS model.

Is it possible to do SI analysis of differential lines with IBIS model for DP83867?

Thanks and best regards,

Shingo

Hi Shingo,

Unfortunately we don't have SGMII IBIS Model available.
