Parallel Link Designer

Analyze PCB designs for parallel link applications

Since R2021b


The Parallel Link Designer analyzes PCB designs for parallel link applications for both pre-layout and post-layout simulations. To perform post-layout analysis, you need a license for RF PCB Toolbox™.

Using pre-layout analysis, you can determine system-level noise and timing margins from integrated signal integrity, waveform, timing, and crosstalk analysis. The pre-layout analysis environment generates design guidelines for your board layouts, package layouts, connectors, and cabling. The post layout environment verifies the actual layout against the design guidelines.


Signal Integrity Toolbox™ recommends you to set the Java Heap Memory to at least 8192 MB when using the Parallel Link Designer app.

Open the Parallel Link Designer App

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

  • MATLAB command prompt: Enter parallelLinkDesigner.

Programmatic Use

expand all

parallelLinkDesigner opens a new session of the Parallel Link Designer app, enabling you to design and analyze a parallel link.

parallelLinkDesigner(path/file.edk) opens the interface designed by the file.

parallelLinkDesigner(file.script) runs a script file and returns the app process handle.
