Seven core considerations will help you realize your PCB for the Internet of Things more effectively.
Reliability is growing to match security as a key challenge for PCB design. These tools and techniques will help you rise to it.
The introduction of the DDR4 memory-bus standard will allow system designers to meet aggressive performance targets for their next-generation systems. But the changes required to support the higher datarates of DDR4 place stringent demands on the PCB designer.
A panel session at DAC 2014 focused on the problems of high-speed, board-level interconnect and the roles of codesign and power integrity in solving them.
Electrical rule checks (ERC) are now available to deal with increasing PCB design complexity, speed project delivery and protect the intellectual property within them.
Advanced PCB and IC technologies have to be matched with advanced design and analysis tools if companies are going to produce board designs that are right first time, on time.
High-speed digital drivers need a good source of power to produce clean, fast signals. For a driver to switch the state of a signal in tens or hundreds of picoseconds, the power plane must be able to supply significant current over a wide bandwidth. The surge in current creates voltage fluctuations in the power distribution […]
Signal integrity (SI) issues have been around for a while, the result of ever-faster edge rates. Both SI and PI problems manifest themselves as data errors. Indeed, PI problems are often misdiagnosed as SI problems. As such, an understanding of power delivery issues is essential to the success of any board project, as is a [...]
Knowing where your application is consuming resources is a crucial step in minimizing energy usage. The article describes a toolset developed by high-profile ARM-based microcontroller (MCU) start-up Energy Micro that helps to achieve this overarching goal within the context of a parallel move to 32bit MCU resolution.
You must find, fix and design out signal integrity problems before committing to hardware. Simulation is the key.
