    Design Rule Verification

    dmitriy2020

      Hello.

      I make multilayer PCB with blind and buried vias. I have a problem with rule verification.

      The rules was made for each layers separately . That way is convenient for my design.

      for example 0.1mm:

      There are blind via (TOP- Signal layer 1) and buried via (Signal layer 1- Signal layer 6 ).  Both of vias are on the Signal layer 1 with distance 0.06mm. 

      1 Checking design rules does not give any errors though the gap is only 0.06mm on Signal layer 1.

      2 If I use a general rule for all leyers  I will get the correct сlearance  constraint error.

       

      Why the rule does not work in the first case? Could you help me with rules for separate layers.
