Differential Impedance Calculation

Dear Community,

I used the differential impedance calculator in the x-section dialog and also the allegro impedance workflow a few times. When we compare that with other calculators on the web and trustworthy tools like Saturn toolkit, we face lots of different results. Saturn to Allegro differ more than 10%, which would result in huge trace width and spacing rules.

Where are these differences come from?

Best regards,

I use the Allegro calculations to get close. Note that the fabricator will adjust width and spacing based on materials they use.
