No.6（2011）11.Design rules check for designing high speed print boards by experiment

Hiroyasu Sano, Ken Sato

  Printed circuit board design rules for noise reduction are very important. The names of design rules themselves are well-know to those who design printed circuit boards, however, parameters for each rule are not well-know nor publicized.
 The authors have chosen two well known rules: "pattern line distance from a board edge" and "gap and width of guarded GND pattern" to examine. Then, at first, we made several sample boards to get actual measurement data for those design rules. Secondary, we compared them with those generated by a simulator to assess the accuracy of the simulation. With the results, we modified simulation models to make them more accurate. As a result, we obtained accurate parameters for selected design rules and concluded that using the simulator was sufficiently effective to design printed circuit boards.
