Optical and Wireline Networks

Telecommunications and signal integrity engineers use MATLAB® and Simulink® to design, simulate, and model many elements of a high-speed digital interface. Popular applications of MATLAB and Simulink tools include:

  • The design of SERDES algorithms such as equalizers and clock data recovery (CDR)
  • Modeling of high-speed backplanes
  • Exploring architectural tradeoffs using system-level simulation
  • Creating HDL, IBIS-AMI, or SystemVerilog DPI models for implementation or validation


A complex DSP model is at the heart of every high-speed digital transceiver. These algorithms include equalizers, clock data recovery (CDR), and coder/decoder functions, which SERDES engineers incorporate in order to meet signal integrity requirements. Due to the mixed domain nature of these simulations, Simulink is the preferred choice for designing and modeling these variable rate mixed-signal circuits.

Linking system-level and circuit-level design tools can lead to faster time-to-market, earlier error detection, and reduced development costs. In this webinar, MathWorks engineers show how these benefits have been achieved and provide examples.

Fast Backplane and Channel Modeling

Signal integrity engineers need efficient, reliable tools that can easily analyze the quality of their high-speed back planes. RF Toolbox™ allows engineers to import N-port S-parameters into MATLAB and create rational functions that model the channel impairments of a passive backplane. These models can then be used in signal integrity simulations to measure jitter or to look at eye closure.

Comprehensive Model Generation

With the breadth of design challenges facing high-speed digital designers, there is always a need for portability of models and connection to verification environments. Simulink allows for model generation in multiple formats including synthesis for hardware, deployment of embedded software, or export for simulation in other EDA environments. Model generation formats include:
