Can you make Z higher?
Simulations should match measurements. Otherwise, what good are they? When doing signal integrity simulations, that starts with comprehensive stackup modeling. I quite often hear that stackup editor calculations don’t match measurements, but when I probe deeper, I usually find that the stackup has not been modeled properly. More often than not, the calculated impedance ends up being much lower … Read More

Break out your calculators boys and girls because it’s math time (well….maybe you won’t need them after you get to the bottom of this post, but it’s fun to dust them off every now and then). The second part of this fundamentals series is going to talk about transmission lines and what exactly is a transmission line and how does it relate to a critical net (from Part 1)
Back in the good ole’ days, …
