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

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

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

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
