Hello,
I have an issue with Allegro calculating the impedances. I have followed this tutorial: https://www.youtube.com/watch?v=XKVQPEIeRT0 but I am getting wrong values. Even if I put same values for cross section as he has in 0:40, mine values for trace thickness with same impedances (and vice versa) are approx. 40 times bigger: https://imgur.com/a/5ktfCpb.
I am assuming there is another settings somewhere which influence this but I am not able to find it. Can someone please help me with this problem?
Thank you in advance.
I am using OrCAD PCB Designer Professional 16.6-2015 S060
