Hi, I have a design where I need to use two or more different via sizes when manually routing some tracking. I have these vias defined and have added them into the via list.
However, the problem is that I cannot select any via other than the first one defined in the list. I'm sure I'm missing something obvious, but cannot find the answer in the help files. So all suggestions are appreciated.
Allegro automatically filters the available vias that match the start and end layer that you have selected in your options box.
It sounds like your vias don't match the board stackup or possibly can only be used on specific layer pairs.
Can't tell without looking deeper at the setup.
