Free SI analysis tools

2017-06-30 by:CAE仿真在線來源:互聯(lián)網(wǎng)

Hi folks-

I am compiling a list of free software tools for signal integrity analysis which I will publish in my PCD&M column in the next few months. If anyone has a recommendation for a free version of a tool, such as a lite version of a full featured tool, or an online tool, please pass me a link offline. Vendors are invited to send me a note as well if you have a lite or student version.

Since there are so many SPICE tools and online impedance calculator tools, I am only going to list one or two of them. I am more interested in link analysis tools, circuit simulators that include differential pair and lossy line models, 2D field solvers, 3D planar and 3D full wave. I will evaluate three key metrics: ease of use, sort of problem it can analyze and limitation of the free version. Any input for this column would be appreciated.

Thanks

Hi Eric/All:

A few things on our site:

1. Visual IBIS Editor:

http://www.mentor.com/products/pcb/analysis_verification/hyperlynx/visual_ibis_editor.cfm

The Visual IBIS Editor is a program for creating, editing, verifying, and maintaining IBIS (I/O Buffer Information Specification) device models. Anyone who uses or creates IBIS models can benefit from using the editor, regardless of whether or not they own any of Mentor's HyperLynx and ICX products. Features:

*A large-file Windows text editor

*Integrated IBIS-syntax-check utility

*A graphical viewer for looking at IBIS V-I tables and waveform tables

*An IBIS-file template generator

*A complete, self-contained online Help system

2. HyperLynx Tutorial:

There's an instructional version of HyperLynx online at www.mentor.com/hyperlynx.

It's the actual software - both pre- and post-layout- but is limited in the files that it will work on. It's accompanied by a complete text tutorial that walks users through some problem solving for SI, crosstalk, SERDES design,and basic EMC issues. (Link is on the right - "Demonstration software and Tutorial.")
