How to measure Net Etch Length considering vias in vertical direction using Allegro？

momo1982

Hi all,

I found that Allegro can't measure net length with via height between the routing layers, which is illustrated in following figures. These two connections actually have a difference of (board thickness * 2), but allegro seems just measure the length in horizontal directions, ignoring the height coming from via.

Total etch length 316 mil here:

Total etch length still 316 mil here. But actually there is a (2*Board Thickness) here which should be considered.

Is there any method in allegro that we can get the REAL net length including the trace length, and via height between the routing layers?

Thanks so much!

  • Hi, My company already had several Allegro PCB designer licenses, including Professional, L (Legacy), and Performance L. I still can't use the High Speed Option? The High Speed Option is a separate license? Btw, the post you shared said"The Z Axis delay is part of the High Speed Option which bolts onto Allegro PCB Designer", but where? I checked my constraint manager, doesn't get any clue. Thanks~
