Parasitic Extraction with an Electromagnetic Solver in PCB Routing

Parasitic Extraction with an Electromagnetic Solver in PCB Routing Parasitic extraction: the integrated circuit design community must grapple with this task on a daily basis, especially once gate features are reduced below ~350 nm and chips run at high switching speeds. The PCB community also has to deal with this idea in order to better design power delivery networks, interconnects with precise impedance, and properly quantify crosstalk and coupling mechanisms. There are many 3rd party applications that can be Read Article

Differential Pair Spacing

Should You Use Tight vs. Loose Differential Pair Spacing and Coupling? We get a lot of questions about trace impedance and how to calculate the right trace size to hit a specific impedance in a manufacturable PCB. Just as important as determining an appropriate trace width for a single-ended trace is determination of an appropriate spacing between two traces in a differential pair. So the question is, how close do the traces in a differential pair need to be to each other, and is the need for “tight coupling” really Read Article

Power Delivery System Design

Power Delivery Systems Design This article is intended to define the new challenges and provide guidance in how to successfully engineer the Power Delivery System (PDS) so it meets the needs of new technologies. As integrated circuit technology allows for billions of transistors on a single IC, it has resulted in very powerful systems on a chip. This has made it possible to put the equivalent of supercomputers inside video games, cell phones, and a host of other products that Read Article

USB 2-layer PCB

Routing Requirements for a USB Interface on a 2-Layer PCB In an earlier blog, I discussed some of the basic points in preparing routing rules for 2-layer PCBs to support routing and layout with digital signals. In particular, we looked at some of the basic stackup and routing rules needed to support a digital interface like I2C or SPI on a 2-layer PCB. When working with these interfaces, a few simple guidelines can help ensure signal integrity in your board and cut down on EMI. What about an impedance Read Article

PCB transmission line calculator

Utilizing a PCB Transmission Line Calculator Makes Design Easier PCB transmission line calculators are a dime a dozen, giving you the tools you need to calculate lossless impedance, lossless propagation delay, or simple things like DC resistance. These quantities are nice to know, but they don't tell you the whole story about your design. Online calculators are also known to give incorrect results when used for impedance calculations, especially because they cannot consider fundamental phenomena like Read Article
