Signal Integrity Issues and Printed Circuit Board Design Douglas Brooks
Publisher: Prentice Hall International

My goal is to build a PCB with an EP3C120 and being able to download a configuration (initially using a .sof file through USB Blaster) to the fpga and connect some of the IO pins to some headers on the PCB, research and testing purposes only. This week, Mentor Graphics released HyperLynx PI, a design software program aimed at improving power integrity on the PCB. Answers Many Questions…With Experience, FACTS & Math…Recommended! Later we would include an external flash memory Power supply and signal integrity issues depend on the frequencies you'll be operating at and also the I/O standards you're using. John Isaac The HyperLynx PI tool was created for designers to evaluate and mesh these power requirements, reducing the need for decoupling capacitators, shortening design times and eliminating respins, and improving signal integrity. When electrons move down a trace or a wire, current flows. If you haven't already read it, hottconsultants.com/techtips/pcb-stack-up-1.html provides a very good overview of tradeoffs among stackup choices various numbers of layers – vicatcu Jan 17 at 19:35 So long as you pay attention to trace impedance, signal return paths, and all of the other usual signal integrity things then you can really do anything with the stackup. By Douglas Brooks – Current is the flow of electrons. Power has Noise, voltage drop along traces, current density variation, and other problems occur. Signal Integrity Issues and Printed Circuit Board Design, Author: Douglas Brooks. Of course, some stackups make it easier to do I have done several PCIe designs and what I do is this:.
