Tech Blog Series: Know How Your Circuit Works! — Understand It Better and Build Powerful Designs

By Ronak Shah | 17 Apr 2018

Using Sensitivity Analysis of PSpice I was thinking of writing a series of blogs showcasing what all ammunition's a circuit designer may need to deal with any complex circuits today. So, here's the first one. When in college, books tell you everything about your circuit. You already know which components are critical in your designs. But, what about when you enter an industry? You have completely new designs that...

Top 10 Reasons Why You Need Allegro System Design Authoring (SDA)

By Rachna2018 | 11 Apr 2018

When it comes to choosing a design-capture tool in the EDA world, there is no one-size-fits-all solution. Depending on a variety of factors, most of all personal preferences, the answer to “Which is the best design-capture application?” keeps changing. Most design tasks can be accomplished in all tools. Some tools might even look similar. In this scenario, what differentiates one product from the rest is highly subjective...

Dude, Where Are Your Files?

By Darin Ten bruggencate | 18 Jan 2018

Let me tell you a funny story. We’ve been working with an outside research agency to write an eBook with new insights into ECAD data management . And based on the findings, I wanted to write a blog about how risky it is to just put your ECAD data on a network or shared drive with a file and folder structure. I thought I had a pretty solid first draft of that blog post written before going away for Christmas. We...

Are You Maximizing Your Product Design? See How a Custom ASIC Can Help

By Darin Ten bruggencate | 24 Jul 2017

When you push more of your board into high-performance design fabric like an SoC, suddenly you have the scope for differentiation and innovation in an SoC that you design yourself. Custom SoCs increase differentiation, reliability, IP protection, security of supply, and performance. They also decrease board size, power, BOM, and cost. Are you ready to take the leap? Many companies are working with custom ASICs these...

Epic Western Movies and PCB Design. Seriously.

By Darin Ten bruggencate | 25 May 2017

I love that recently Westerns movies are making a comeback. Something about the romanticism of a hired gun coming in with no baggage, looking at the situation pragmatically, and doing what everyone knows needs to be done, but just can’t. Once Upon a Time in the West and The Good, the Bad and the Ugly , Sergio Leone’s epic Spaghetti Westerns, aren’t the only foreign influence on what we think of as American Westerns...

By Vincent Di Lello | 5 Jan 2017

Most of the PCB designers I know are creatures of habit just like I was... we have our favorite colors, layer names, customized keyboard and our number one goal is to see how many nets we can route in one day. Very rarely do we change – but when we do it’s either because we changed employers or we are forced to because the tried and true processes don’t work any longer. Can you relate?

Why Move Up to Allegro 17.2-2016? Via Structures - The Next Generation High Speed Routing Solution (Reason 8 of 10)

By Marita Baldwin | 18 Nov 2016

Via transitions are very common for signals. And in high speed frequencies, these via transitions can be a major contributor to signal degradation in PCB interconnects. High speed channels require ground via(s) close to critical signals to reduce loss of signal integrity by providing continuous return current path when signals transition layers. If you are a PCB design engineer, you know very well that layout implementation...

By Marita Baldwin | 11 Nov 2016

Improve Route Channel Utilization with Tabbed Routing Tabbed routing is a new method in which trapezoidal shapes called tabs are added to parallel traces to control impedance in the pin field/breakout regions, and reduce crosstalk in open field regions. It is a breakthrough routing strategy that allows for longer trace lengths and more compressed routing. Unfortunately, this new routing technology increases...

We are not talking about how your design compares to the next guys’, we’re talking about the PCB layer structure of your design, be it rigid, flex, rigid-flex, or using inlay technology.

Why Move Up to Allegro 17.2-2016? New Enhanced Backdrill Capability (Reason 4 of 10)

By mcatramb91 | 26 Sep 2016

Adventures in Backdrilling For the past 15 years or so, routing high-speed interfaces handling 5Gbps or higher have become more common in many electrical designs. Transitioning high-frequency signals between layers can greatly affect signal integrity when a portion of plated through-hole (PTH) is left unused, forming an electrical stub. In general, these stubs are a source of impedance discontinuities and signal reflections...
