Hi, I have a question for add couple line on Speed200. I know how to define the couple line on Speed2000. When I has a 4 Layer Board, the board have many irregular Tr-Line and smash GND Plane (imperfect plane). I don't know whether you have any skill to deal properly with the question. Would you please tell me to deal properly with the question? Thanks very much.
