SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you model, simulate, and deliver high-speed SerDes systems in MATLAB without getting stuck on missing or misconfigured equalization, channel, and IBIS-AMI export details.

Core Features & Use Cases

  • System-level SerDes modeling and analysis: Build NRZ and PAM-N (PAM3–PAM16) SerDes systems and run statistical analysis (eye diagrams, COM/EH/EW, jitter decomposition).
  • Channel modeling from loss, S-parameters, or captured waveforms: Use ChannelData with loss models or load Touchstone files via SParameterChannel, including multi-port crosstalk scenarios.
  • Equalization architecture exploration and optimization: Configure and tune FFE/CTLE/DFE/DFECDR (including adaptive Mode=2 workflows and common gotchas like WaveType, modulation, and parameter locations).
  • IBIS-AMI delivery and validation: Export to Simulink and generate compiled .ami/.ibs and platform-specific binaries (DLL/SO), then validate behavioral vs compiled outputs.

Quick Start

Use the matlab-model-serdes-systems Skill to build a SerDesSystem for a target PAM4 link from your S-parameter file, run analysis, plot the statistical eye, and export a validated compiled AMI model.

Frequently Asked Questions about matlab-model-serdes-systems

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I model a SerDes system in MATLAB using Touchstone S-parameters?▼

To model a SerDes system using S-parameters, load Touchstone files via SParameterChannel into your MATLAB SerDesSystem. This enables channel characterization for NRZ or PAM-N links, supporting multi-port crosstalk scenarios for accurate statistical analysis.

How do I export an IBIS-AMI model from MATLAB SerDes Toolbox?▼

You export IBIS-AMI models by generating compiled .ami/.ibs files and platform-specific binaries (DLL/SO) from your MATLAB SerDesSystem. The workflow includes validating behavioral outputs against compiled outputs to ensure consistent link delivery.

Can I simulate PAM4 equalization with adaptive DFECDR in MATLAB?▼

Yes, you can simulate PAM4 equalization with adaptive DFECDR by configuring Mode=2 workflows in MATLAB. This requires explicit WaveType and PAM modulation settings to ensure correct adaptive behavior during statistical analysis and eye diagram generation.

Why does my MATLAB SerDes simulation fail with incorrect DFE adaptive behavior?▼

DFE adaptive behavior fails when integer SamplesPerSymbol, explicit WaveType, or PAM modulation settings are misconfigured. Enforcing correct SerDes Toolbox usage requirements, including Mode-specific DFECDR parameters, ensures consistent analysis-to-export validation.

What is the best way to tune FFE and CTLE equalization for high-speed channel modeling?▼

The best way to tune FFE and CTLE equalization is configuring these parameters within a MATLAB SerDesSystem using loss models or captured waveforms. This allows optimization across NRZ and PAM-N architectures while extracting jitter and waveform metrics.
