    Counting via/contact in a certain area


      Hi.  I am new to Calibre rule file making.

      It is possible to check the number of via on metals?


      Example: Check if at least two contacts(cc) are use between metal1 and metal2.


      My idea


      x = metal 1 AND metal 2 AND cc

      y = metal 1 and metal 2 // this is the area with cc

      z = compute area of y

      area_cc = 0.78 //from design rule


      if z/area_cc =>2 then no error

           else show error flag


      how to implement this in calibre?


      thanks in advance!
