for Embedded System PCBs

The requirement for high-speed design has brought about a number of design challenges never associated with low-speed devices. The ever increasing clock speeds have transformed digital switching circuits into RF generators, which is critical and not easy for the PCB layout task. Other factors which may occur at higher speeds in the embedded system are signal and power integrity problems due to impedance variations caused by switching problems or overheating. The good news: the limited functionality required from embedded systems permits these to be designed for much more efficient performance.
