SerDes Toolbox


SerDes Toolbox

Design SerDes systems and generate IBIS-AMI models for high-speed digital interconnects

Get Started:

SerDes Design

Design SerDes systems using parametrized white-box models and algorithms.

SerDes Designer App

Design, configure, and analyze SerDes systems using the SerDes Designer app. Model channel attenuation, dispersion, jitter, and crosstalk. Check performance metrics such as channel operating margin (COM), using reports, eye diagrams, bathtub curves, and other visualizations. Use MATLAB to automate analysis, reporting, and design space exploration. Generate Simulink and IBIS-AMI models for further refinement and verification.

Adaptive Equalizer Design

Use DFE, CTLE, FFE, AGC, and CDR to design adaptive equalizers. Use parametrized blocks and algorithms for single-ended and differential signals.

Starting with the white-box implementation, customize models with your own algorithms.

Explore local and global adaptation strategies to optimize your system performance, and generate IBIS-AMI models.

SerDes Analysis and Simulation

Perform statistical analysis with the SerDes Designer app and create a Simulink model for time-domain simulation.

Statistical Analysis

Perform statistical analysis to compute and visualize eye contours, bit error rates (BER), bathtub curves, COM, and other metrics using the SerDes Designer app.

Explore the design space of your equalization algorithms and channels using PAM4, PAM3, and NRZ modulations.

Time-Domain Simulation

Perform time-domain simulation of adaptive algorithms using customizable Simulink blocks and channel models that capture frequency-dependent attenuation, reflections, and arbitrary impulse responses.

Verify your equalization algorithms using pseudorandom binary sequences (PRBS) and custom stimulus patterns.

IBIS-AMI Model Generation

Generate standard-compliant IBIS-AMI models for use in third-party channel simulators.

Dual Model Generation

Generate IBIS-AMI statistical (Init) and time-domain (GetWave) algorithmic models with associated analog IBIS models. Customize the model interface by managing IBIS-AMI parameters from the SerDes Designer app and Simulink.

Channel Analysis and IBIS-AMI Simulation

Use the Signal Integrity Link to export IBIS-AMI models into Signal Integrity Toolbox for analyzing serial links and parallel interfaces. Verify IBIS-AMI models with statistical and time-domain simulations, explore the design space, and prove standard compliance. Optimize your SerDes design by importing back corner cases including stimuli, AMI parameters, and channel models.

You can also use the generated IBIS-AMI models with third-party channel simulators such as Keysight™ ADS, Synopsys® HSPICE, Mentor Graphics® HyperLynx®, and Cadence® Sigrity SystemSI.

Reference Designs

Use white-box blocks to model industry-standard communication protocols such as PCI Express, DDR, and Ethernet.

Standard-Compliant Reference Models

Use standard-compliant reference designs of PCIe Gen4, DDR5, and OIF CEI-56G. Get started with reference models and refine them to design next-generation communication protocols using NRZ and higher-order modulation schemes such as PAM3 and PAM4. Generate standard-compliant IBIS-AMI models for verification.
