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

A DIMM is more than some DRAMs on a PCB. However, this feature is not available in the Allegro PCB Editor tool. Different Layout Techniques in PCB; PCB Design Tools; Guidelines for Designing PCB; Signal Integrity Problems in PCB Design; How to Make PCB? Incorrect impedance may cause signal integrity issues. Inadequate power plane designs may cause random ECC errors. Grzenia on March 25, 2009Comments(2)Filed under: PCB design, SPB 16.2, Cline change, APD. HyperLynx PCB Analysis Blog: The HyperLynx team discusses Signal & Power Integrity issues in today's digital designs. May 3rd, 2010, by Steve McKinney | Permalink · Share. Cadence recently acquired FPGA/PCB "co-design" technology that automates and optimizes pin assignments, and PCB signal-integrity software is widely available. Several things could go wrong - including pin assignments that don't work in the board layout, signal integrity problems on the board, and parasitic package inductance. Our APD AE expert, and in the SPB16.3 APD tool, there is an Edit> Cline Change Width command. This week, Mentor Graphics released HyperLynx PI, a design software program aimed at improving power integrity on the PCB. Fortunately, help is available for each of these problems. 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. In IC package design, it is becoming increasingly necessary to change a cline's width in a given region, whether for signal integrity reasons or to allow all necessary traces to pass through a particularly dense region. Power has Noise, voltage drop along traces, current density variation, and other problems occur. Incorrect PCB stack-up may cause crosstalk issues.
