Single ended model in serial link designer app

Hi all,

I am designing a single-ended serial link and I am trying to evaluate my s-parameter channel and equalization scheme in serial link designer app. But it seems every tx and rx model that comes with installation is differential. Also, "single-ended" option seems to be unavailable in many places (as attached in the following images). Do I have to build my own AMI-IBIS model to simulate a single ended channel? I tried to tie one of the differential terminals to a fixed voltage level to make things single-ended, but is there a better way?

Thanks in advance!

Hi,

You need to build your own IBIS-AMI model to simulate a single ended channel while designing a single-ended serial link. IBIS-AMI models are used to verify the overall link performance and optimize the equalization algorithms.

The algorithmic models describing adaptive equalization are simulated together with the analog channel described by means of Spice, IBIS, analytical models, and S-parameters.

• Please refer the below documentation for how to use ‘IBIS-AMI’ models: https://in.mathworks.com/discovery/ibis-ami.html
• Please refer the below documentation for creation and customization of ‘IBIS-AMI’ models: https://in.mathworks.com/help/serdes/create-and-customize-ibis-ami-models.html

I hope it helps!
