SerDes Toolbox™ provides a MATLAB® and Simulink® model library and a set of analysis tools and apps for the design and verification of serializer/deserializer (SerDes) systems or high-speed memory PHYs such as DDR5.
With the SerDes Designer app, you can use statistical analysis to rapidly design wired communications links. The app provides parameterized models and algorithms that let you explore a wide range of equalizer configurations to improve channel performance. You can assess metrics such as eye diagram, bathtub curve, and channel operating margin (COM), including the effects of jitter and crosstalk.
With MATLAB based building blocks such as CTLE, DFE, FFE, and CDR, you can describe your chosen architecture using datasheets or measurement data and simulate control and adaptative algorithms. White-box examples of typical applications such as PCIe, USB, Ethernet, and DDR provide reference designs that you can use as a basis for your own designs.
SerDes Toolbox supports automatic generation of dual IBIS-AMI models for statistical analysis and time-domain simulation. These models can be used with channel simulators for system integration and verification.
Get Started:
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.
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.
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.
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.
