As technology trends towards smaller, faster, cheaper, the challenges around good PDN design are getting more difficult. With multiple requirements needed from many disciplines, the demands of the PDN are only going to increase and become harder to maintain.

We’ve discussed the importance and care required when routing the power delivery network (PDN) of modern printed circuit boards. From how to support current supply needs, loop inductance, to defining layer stack-ups, it may seem like we’ve addressed all the power concerns one could have.

Fast interfaces and switching speeds are becoming commonplace and with that comes increased noise, amplifying any problems within the power delivery network. Products today are the direct result of the fast signal capabilities in current technology, making it impossible to completely eliminate noise.

Achieving a robust and functioning power distribution network isn’t difficult, if we provide both the capacity and responsiveness needed at each device. Previous articles addressed capacity concerns, discussing the need for sufficient copper (or an alternative conductor) between a voltage source and any load depending on it for its supply.

Lately, much of the talk in the simulation world seems to be about power. Even SI experts are starting to see how power has a material impact on their highspeed data transfer success. With power on the forefront, what effect will that have on the additional design demands of low-frequency supplies? Why should you consider power throughout your design process?

Two of the most compelling forces driving much of our technology, Miniaturization and Performance are not new. In fact, one could say they have appeared within every product spec and design document in some form or another since the terms were coined. Fundamentally, this is great and has enabled capability and portability with products in virtually every hardware sector.

As the simulation and analysis industry continues to mature, it is evolving from a "mechanism for finding problems" to a "methodology for preventing them". Many design teams have advanced beyond just checking for violations and are using the tools to make informed design decisions early in a product’s development. This results in better products reaching production floors despite condensed schedules.

The inherent need to address signal quality challenges is no longer limited to just high-end, high-speed, signal integrity experts. OrCAD provides an integrated analysis environment with powerful simulation technology beginning at the schematic level. Seamless pre-layout analysis is available directly inside the OrCAD environment at no additional cost to you. Identify a wide array of signal quality issues including overshoot/undershoot, ringing and delay among many others. With advanced features including powerful analysis capabilities of Signal Explorer and SigWave, you can now explore and eliminate signal integrity problems early in your design process during schematic entry in OrCAD Capture.
