Hello! I'm designing a 6-layer board and I'm having difficulty getting the blind and buried vias correct in the Layers DRC window. Here's what I currently have:
The setup equation is: ([2:1+(2*3)+[3:(14*15)]+16:15]). However, with this equation, Eagle will not let me set a via to go from layer 3 to layer 14 (or vice-versa). I'm not really sure why this is the case but I assume it's because the equation is using blind via notation for a buried via. I've tried modifying the equation to create a buried via between layers 3 and 14, but I haven't had any success. Is it possible for me to get a buried via between layers 3 and 14 with the other vias the same as pictured, and how would I set the equation to accomplish this? Thanks!
