To begin this series on fundamentals of signal integrity, lets start at the very beginning.  Before you start doing any type of simulation or analysis, what do you have to do first, what information do you have to know?  Your design probably has thousands of nets, are you going to simulate all of them??  Probably not, there’s not enough time for that and truthfully, it’s not really necessary.  The first

AMI - The next modeling frontier

Posted by Steve McKinney

If you do any kind of multi-gigabit SerDes design, you’ve probably come across the acronym, AMI - Algorithmic Modeling Interface.   AMI is essential a fast behavioral model of multi-gigabit transmitters and receivers.   Standard IBIS models are good for regular switching edges up to some surprisingly fast speeds, but when you start adding in things like pre-emphasis, and equalization on those edge,

Robin Bornoff Lumped block package representation makes the best use of limited available data to simulate for an ‘indication’ of case temperature. Some indication is better than none but I wouldn’t bet on it, really, I wouldn’t. Accurate case and junction temperature prediction can only be realised with either a fully 3D detailed representation or an abstracted CTM (compact thermal model) representation. Here we’ll … Read More
