SerDes Designer

Design and analyze SerDes systems for export to Simulink, MATLAB and IBIS-AMI

Description

The SerDes Designer app generates the SerDes Designer tree required to generate IBIS-AMI models. Start from the app to develop initial SerDes architecture using statistical analysis and manage developed models.

Using this app, you can:

• Create fully compliant IBIS(Input/Output Buffer Information Specification)-AMI(Algorithmic Modeling Interface) models and perform statistical analysis.

• Generate MATLAB scripts for further customization and statistical and time domain analysis.

• Export Simulink models for further customization, statistical and time domain analysis, and IBIS-AMI model generation.

To know more about this app, see Design SerDes System and Export IBIS-AMI Model.

Open the SerDes Designer App

• MATLAB^® Toolstrip: In the Apps tab, under Signal Processing and Communications, click the app icon.

• MATLAB command prompt: Enter serdesDesigner.

Programmatic Use

serdesDesigner

serdesDesigner opens a new session of the SerDes Designer app, enabling you to design and analyze a SerDes system.

serdesDesigner(serdesDesign)

serdesDesigner(serdesDesign) opens the SerDes Designer app and loads the serdesDesign file saved from the previous session.

Limitations

IBIS-AMI codegen is not supported in MAC.

More About

Configuring SerDes System

The SerDes Designer app provides built-in configuration settings for customizing your SerDes system. From the app toolstrip, go to CONFIGURATION tab, and select relevant settings.

Parameter Name	Default Value	Description
Symbol Time (ps)	100
Samples per Symbol	16	Choose between 8, 16, 32, 64, and 128
Target BER	1e-6
Modulation	NRZ	Choose between NRZ and PAM4.
Signalling	Signaling	Choose between Differential and Single Ended.

Setting Up Transmitter and Receiver

Use the AnalogOut subsystem to set up the transmitter.

Use the AnalogIn subsystem to set up the receiver.

From the app toolstrip, go to the BLOCKS tab, and use the relevant blocks. The app provides the following building blocks:

• FFE

• CTLE

• DFECDR

• CDR

• AGC

• VGA

• SaturatingAmplifier

• PassThrough

Statistical Analysis

From the app toolstrip, go to ANALYSIS tab, and select Add Plots to perform statistical (Init) analysis. By default, Auto-Analyze is selected, and plot results are automatically updated with each change in the SerDes system. You can deselect the Auto-Analyze, and update the plot at your preference by clicking the Analyze button.

You can view the following plots from the app:

• Pulse Response

• Statistical Eye

• PRBS Waveform

• Contours

• Bathtub

• Report

• BER

Exporting SerDes System

From the app toolstrip, go to EXPORT tab. You can either:

• Export SerDes System to Simulink

• Generate MATLAB Code for SerDes System

• Make IBIS-AMI Model for SerDes System

Extended Support with Other Compilers and Products

Note

• If you have Simulink^® license, you can export Simulink and IBIS-AMI models from the app.

• If you have a supported compiler, you can compile the SerDes system in that compiler from the app. For a list of supported compilers, see Supported and Compatible Compilers.

• If you have the following licenses: MATLAB Coder™, Simulink Coder, and Embedded Coder^®, you can keep your C files during .dll file generation. Otherwise, your C files will be deleted during the .dll file generation.
