Hi,
how often do you run signal integrity to test your PCB. What kind of terminations do you use.
I draw PCB which have components with 1ns rise time.I import IBIS models and setup layer structure. Most of tracks are shorter than 40mm(1.5inch) and their with is 6mils. I run Signal...
Hi,
I am using Altium. I import ibis model but i don't know which technology I have to set.
I get issue about logic levels if I don't set technology. Does IBIS model contains data about technology?
I think that the IBIS model should contain logic levels.
How should I set SI-models to get...
Hi,
this is copied from AP0107 Impedance-Controlled Routing.pdf from Altium
The speed at which the electrical energy can travel along the route it known as the propagation velocity, where
VP = speed of light / √dielectric constant
Using
Time = 1/3 * rise time
εR = 4.7 (approximation for FR4)...
altium add net tie
Hi,
When I use Situs-auto router(Altium designer). I always get a lot of
What should I change to get less Short-Circuit Constraint. I use bga-footprint and under bga I get short-circuit.
