Create and Customize IBIS-AMI Models

Customize, create, and export IBIS-AMI models from Simulink

Use the SerDes Designer app to develop a SerDes system based on statistical BER analysis. Export the SerDes system to a Simulink^® environment.

Customize the building blocks to perform further statistical and time-domain analysis. Modify the AMI parameters to transfer them to AMI model executables (DLLs). Once you are satisfied with the system, you can generate the IBIS-AMI model from Simulink.

Apps

SerDes Designer

Design and analyze SerDes systems for export to Simulink, MATLAB and IBIS-AMI (Since R2019a)

Topics

Signal Integrity Link
This example shows how to test the IBIS-AMI SerDes models developed in SerDes Toolbox™ using the Signal Integrity Toolbox™.
Manage Contents of IBIS and AMI files
Manage the contents of the generated IBIS and AMI files using SerDes IBIS-AMI Manager.
Understanding IBIS-AMI Simulations
Learn how IBIS specifications are used in statistical and time-domain simulations.

Featured Examples

Managing AMI Parameters

Add, delete, modify, rename, and hide AMI parameters for an IBIS-AMI model built with SerDes Toolbox™. These AMI parameters are then available to be used with existing datapath blocks, user-created MATLAB® function blocks or optimization control loop, and can be passed to or returned from the AMI model executables (DLLs) created by SerDes Toolbox.

Design IBIS-AMI Models to Support Rx Decision Time

Create Rx AMI models that support Rx Decision Time as defined in the IBIS (I/O Buffer Information Specification) version 7.1, by modifying the library blocks in SerDes Toolbox™. This example will use a typical SerDes Rx AMI model to demonstrate the setup.

Design IBIS-AMI Models to Support Clock Forwarding

Create Rx AMI models that support clock forwarding as defined in the IBIS 7.1 specification by modifying the library blocks in SerDes Toolbox™. This example will use a DDR5 write transfer (Controller to SDRAM) to demonstrate the setup.

Design IBIS-AMI Models to Support DC Offset

Create Rx AMI models that support DC Offset as defined in the IBIS Buffer Issue Resolution Document (BIRD) 197.7 by modifying the library blocks in SerDes Toolbox™. This example will use a DDR5 read transfer (SDRAM to Controller) to demonstrate the setup.

Simulate Crosstalk Cancellation in IBIS AMI Receiver Models

Simulate crosstalk cancellation in a SerDes Rx AMI model. You can disable crosstalk cancellation or select a specific aggressor column in the impulse_matrix to cancel. You can also replace the filter used in the example cancellationFilter.m with a CTLE that represents the filter implemented in the hardware.
