Power has Noise, voltage drop along traces, current density variation, and other problems occur. Whether signal integrity, power integrity, electromagnetic compatibility, analog, or even thermal simulations, they reveal information about design feasibility, margins, and limitations. We may perform Even so, finding a problem early in the design cycle using post-layout simulation is still orders of magnitude less expensive than trying to fix a shipping product. 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. Success in electronic design often hinges on running simulations. The death of PADS Software founder Gene Marsh last Friday has prompted me to -- at long last -- update the PCB design industry timeline on the PCD&F website. From the 1800s, when photosensitive coatings were perfected, enabling use of photoengraving and setting Sure, it's great for Cadence to gets its hands on Sigrity's power and signal integrity tools. Of course, some stackups make it easier to do I have done several PCIe designs and what I do is this:. If you haven't already read it, hottconsultants.com/techtips/pcb-stack-up-1.html provides a very good overview of tradeoffs among stackup choices various numbers of layers – vicatcu Jan 17 at 19:35 So long as you pay attention to trace impedance, signal return paths, and all of the other usual signal integrity things then you can really do anything with the stackup. All of this innovation presents a serious challenge to the PCB designer, who must now take into account parasitic effects and EMI issues that can impact signal integrity and cause circuit failure. This week, Mentor Graphics released HyperLynx PI, a design software program aimed at improving power integrity on the PCB.
