Free IBIS Simulator: KiCAD 8?

March 24, 2024 by Rolf Østergaard

A long time ago I did a series of posts about Altium for signal integrity (part I, part II, part III). That did not go well for Altium. Ever since then, I have been on the lookout for a free or cheaper alternative to the kings of the mountain of signal integrity simulation: Hyperlynx and… Read more

Simulating SSN with Hyperlynx

June 9, 2014 by Rolf Østergaard

Figuring out how to simulate ground bounce, Vcc bounce, SSN, SSO (or whatever you want to call it) is not trivial – this is a step-by-step guide to doing Hyperlynx SSN simulations right. This being so difficult is actually a shame, as it can very well be the most significant factor in your signal integrity… Read more

Using Cadence SigXplorer for Parallel Termination

February 6, 2014 by Rolf Østergaard

Some of the EE-Training courses use the Cadence SigXplorer tool, which is a very handy IBIS*) simulator. I have previously written about other similar tools like the simulator-part of Altium and Mentor’s Hyperlynx. It’s not really important what tool you use, it’s more how you use it and what you do with the results. IBIS… Read more

Altium Signal Integrity Tool – Part III

September 10, 2012 by Rolf Østergaard

As part of a series of real-life simulations on a very simple part of a circuit I try to figure out just how Altium vs Cadence (SigXplorer) compares. The Altium price is right, but is it up to the job? Last time I looked at input voltage waveforms and realized we needed a termination scheme… Read more

Altium Signal Integrity Tool – Part II

September 3, 2012 by Rolf Østergaard

In part I of this series of comparisons I started my quest to figure out if Altium is any good for SI analysis. It’s clearly one of the cheapest tools out there that allows you to do IBIS model-based simulations. Forgetting the price, can it get the job done? Last time I did a very… Read more
