We have a MAGIC problem that perhaps someone has solved and would be willing to share a fix. Our latest technology has a third level of metal, so we've added a ninth plane and worked out the colors and stipples. If I put via2 (connecting m2 to m3) in the metal2 plane, I can draw via2 over regular contacts (connecting the active plane to m1) but not over via1s (connecting m1 to m2): whenever via2 is painted over via1 (or vice-versa), the latter gets replaced. All that is good. The problem is with the contact section of the tech file. For many reasons I need to add the line via2 m2 m3 line to the contact section. But when I put the above line in, via2 can no longer be placed over regular contacts: the contact is deleted when via2 is drawn over it. Any help would be appreciated. ################################################################## # # # George Entenman (ge@mcnc.org) # # The Microelectronics Center of North Carolina # # P.O.
