![]() In other words, signal integrity refers to electronic circuit tools and techniques which ensure that electrical signals are of sufficient quality for proper operation. Electronic signals, particularly high speed signals will deteriorate, distort or oscillate if the designer has not made allowances for impedance matching and signal transmission effects. In general, signal integrity refers to the quality of an electrical signal or pulse on the interconnect track of a PCB or component. ContentsĬonclusion Introduction Physical Description A methodology is presented in this tutorial for the analysis and the characterization of a simple via hole in multilayer PCB. For this reason an accurate modeling of discontinuities at PCB level is essential for signal integrity (SI) analysis. The layout of printed circuit boards (PCBs) involves a large number of discontinuities, and their presence causes signal distortion and all the related problems for the mounted digital devices. The miniaturization and the large-scale integration of electronic devices place increasing demand on the multilayer interconnect geometry.
