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

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. Perhaps this is it, perhaps it's not just the signal integrity, the EMC, the mechanical constraints or for that matter how it's going to fit into the case It's all of it.

However, this feature is not available in the Allegro PCB Editor tool.

ODB++ is common format and can be generated from almost any PCB tool. Ensuring good Signal Integrity (SI) in high-speed communication PCBs is becoming more challenging as layouts become more complex, the PCB. For high-speed digital applications, the use of RO4350B with LoPro foil enables circuit designers to not only preserve signal integrity but, with the 0.004-in. Thickness of the material, to accommodate complex multilayer designs while keeping overall thickness low. The Allegro and OrCAD PCB Design Release 16.3 brings PCB engineers significant new benefits, including the ability to miniaturize the footprint of their end product and reduce the number of physical prototype iterations, making the design cycle more Usability improvements are another focus of the latest Allegro PCB Signal and Power Integrity software, which offers a new user interface and adds stack-up-aware capabilities to the pre-route analysis environment. One way that most electrical engineers have traditionally dealt with the problem of temperature rises at the circuit-board level has been by specifying printed-circuit materials with lower dissipation factors. Must first install CST Link on Cadence Tool, then export portion of design file. PCB design isn't playing with coloured lines to join the dots.
