Signal integrity simulation with OrCAD


Signal integrity or “SI” is a measure of the quality of electrical signals sent from driver to receiver. Deep explanation of SI terms and issues is provided in Chapter 6, Printed circuit board design for signal integrity. Here we will explain briefly how the SI issues in your printed circuit board (PCB) design can be solved with the help of OrCAD Signal Explorer tool (which is included to the OrCAD Professional bundle), or with more powerful tools, such as OrCAD PCB SI, Sigrity ERC, or Sigrity Advanced SI/Advanced PI.
