PCB: From-To-Editor (AD14 versus AD15)

Looking at the same net using the From-to-Editor

AD14.3.18  (length 1864 mils)


AD15.1.15 (length 1965 mils)

Why the difference ?

AD14.3.18 does NOT account for the length of the vias in the routed path.

AD15.1.15 does account for the length of the vias in the routed path.

This 100 mils is a very significant difference for high-speed designs.

Use AD15.1.15 or higher to account for the vias !

That's It.
