Via modeling - what do I really need?
The whole via simulation issue is admittedly complicated, and I think really boils down to whether the vias are single-ended or differential, and at what speeds you are running.
When the vias are differential, the return current is basically self-contained around the vias since they have equal but opposite signals on them. Because of this, the built-in analytical model in HyperLynx models differential … Read More

A couple of weeks ago, two things happened. First, I changed television/Internet suppliers. Second, AT&T, who had initiated flat-rate service for both voice and data on their cell network, stopped taking orders for the data portion.
So, how do these items go together, and how am I going to tie this to a Mentor product? Here’s the answer to the first question; I hope to figure out how I’m going to …
