Simulating SSN with Hyperlynx

June 9, 2014 by Rolf Ostergaard

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 Ostergaard

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 Ostergaard

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 Ostergaard

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

Altium Signal Integrity Tool – Part I

August 27, 2012 by Rolf Ostergaard

How good is Altium for signal integrity? This is a question I get asked a lot. The price is right – you basically get the SI simulator for free as part of the schematic/layout/mechanical etc. package. With cheap comes natural skepticism. We are used to fairly expensive dedicated SI tools from the big players like… Read more
