BoardSurfers: PCB Electronics - Defining and Applying Physical and Spacing Constraints

By mrigashira | 17 Sep 2019

If you get frequent calls from your fab houses or your customers regarding your product, or if your schematic, layout, and packaging engineers spend a lot of time exchanging notes about their requirements not being met, resulting in back and forth of designs, or if you believe, like most of us do, that a product should do what it was designed to do, constraints are your friends.

DATA Pulse: Track Your Components—Efficient Library and Design Data Management

By Auromala | 15 Sep 2019

Ever noticed how some objects always mysteriously disappear? It's like they have their own legs. Or maybe, secretly, they thirst for adventure and go wandering off. Socks for example. Why does one twin always disappear after a round in the washing machine? After a few months, you just have a sad pile of lonely, orphaned socks in a variety of colors. Pens are equally guilty. They're always disappearing. Pen caps are even...

BoardSurfers: PCB Electronics - Electrical Constraints

By mrigashira | 10 Sep 2019

Whether it's NASA's space missions or a school camping trip; building a cutting-edge, reusable rocket system or baking a simple lemon tart - planning is a must to avoid disasters, or at least to get a predictable output. So is the case with PCBs. You want to plan ahead to avoid design mistakes that can cost you money and time. And that's where constraints come handy.

BoardSurfers: PCB Electronics - Component Placement - Get Set and Go!

By mrigashira | 3 Sep 2019

How do you place components on a PCB design? Manually? Or quickly using automation? Is there a way to rotate or mirror components while placing them? Is there a way to determine the congested areas or the flow within blocks even while placing components? How do you ensure the placed components are aligned? How o you verify all is well with the board? Read on for the answers.

BoardSurfers: PCB Design Technique for Designing a Small RF Section in a Digital Board

By Surender | 28 Aug 2019

Are you designing a 5G or radar application, or for that matter any application, that requires RF components? Are cost, size-reduction, and performance improvement major concerns for you? Most probably they are. Here we talk about an innovative solution for mixed-signal RF designs using Cadence layout editors.

BoardSurfers: PCB Electronics - Six Things to Do Before You Actually Place Components on a PCB

By mrigashira | 20 Aug 2019

It's a PCB you are designing. Where do you start? What can you do to make your process more productive and efficient? Are you feeling at lost? Worry not. We will talk about the six things you do before you start placing components on the board, and, of course, if you use PCB Editor, there is the Design Workflow guide to ease the board design process for you.

DATA Pulse: Playing Favorites with Parts—Influencing Design Part Selection with a Preferred Parts List

By Auromala | 18 Aug 2019

Life is full of decisions - what college major to opt for, which career path to follow, whether to move cities for a job or stay put, whether to switch career paths midstream for a more fulfilling life. You know what I mean. As a librarian, your professional life is as full of choices and decisions to be made. OK, so maybe they're not as life changing as the ones I've just listed, but they're important. However, it...

BoardSurfers - Aerials and Bails: How to Rename Reference Designators Using Batch Command

By Monika | 6 Aug 2019

Components on a board are often placed per their functional group and hence their reference designators are all jumbled up. It is a common practice to rename reference designators before sending out the design data to manufacturers. Reference designator...

BoardSurfers: Capturing Design Intent for Automatic Routing in PCB Editor

By mrigashira | 31 Jul 2019

Imagine you are designing a complex board with thousands of interconnects and all the usual complexities inherent in a dense design that is also highly constrained. Well, it's easy, the 'imagine' part; and you don't even have to try like John Lennon had crooned in his Imagine song, because most probably you are actually designing one right now that is dominated by bussed interconnect. And most probably your mind is stretched...

BoardSurfers: Designing a Rigid-Flex Board Using PCB Editor

By mrigashira | 26 Jul 2019

Whether you are designing the latest pace-maker or a LED strip, you have definitely pondered awhile about rigid PCBs and flex PCBs. You might have gone through a pile of literature, called up friends who have already done it (after all flex PCBs have been around for more than half a century now), and deliberated with your team to finally settle on a rigid-flex PCB. Well, what had started as a cutting-edge requirement...

DATA Pulse: In Search of the Perfect Environment—Configuring Allegro EDM

By Auromala | 22 Jul 2019

Ah, the office temperature – that eternal debate. As in many offices, ours has some people who feel that they're in the Sahara Desert, others who bundle up like they're in Antarctica, a few who just don't care about the temperature, and some who can't quite figure out if they're ever comfortable, like Goldilocks. There is however no 'perfect' temperature. So many variables impact the physical environment of the office...

BoardSurfers: Avoid Iterations with Your Manufacturing Partner – Detect and Address DFM Issues in the Design Phase Using DesignTrue DFM

By mrigashira | 16 Jul 2019

Some things are rare, good or bad, but they do happen from time to time. And, some happen so regularly, we often take them for granted if good or learn to live with them if bad. But should we? For example, you send out your design for fabrication and the CAM (computer-aided manufacturing) engineer runs a high-end design for manufacturability (DFM) analysis software. The CAM engineer sees DFM issues (almost always!)....

In part 1 of this two-part blog post, we analyzed how you can define a parts lifecycle manager, define and assign lifecycle states to parts, then distribute the latest parts to designers. In part 2, you're the designer and you want to know which parts to use in your design. The initial PCB design – how did you come up with it? Doodled it on a piece of paper? Hashed it out in conference room meetings where at least...

BoardSurfers - Aerials and Bails: Take a Walk on the Wild Side...with Auto-Roaming

By Tyler | 25 Jun 2019

We have had this question before, so it’s a good one to remind everyone of in case you’re not aware of it. What I usually hear asked is how can you have the tool automatically pan/roam when your cursor gets to the edge of the canvas. The good news is that this is there today for you; it may just be that you don’t realize it! To make sure that you don’t pan the canvas at times when you don’t intend to, you will have...

BoardSurfers - Aerials and Bails: How to Split a Viastack

By Monika | 20 Jun 2019

Today’s compact and powerful devices require small and high-density PCBs. Tight routing around densely packed components is thus indispensable, but cannot be achieved using conventional blind-buried and through-hole vias. Consequently, stacked vias have become an essential element of contemporary PCB designs. Stacked vias can be used in place of through-hole vias by placing multiple vias exactly over each other, taking...

This is the first of a two-part blog post on managing part obsolescence using Allegro ® EDM applications. In the midst of a periodic bout of decluttering the house, my niece stumbled across some cassettes and looked at them like they were from some prehistoric age. How could I convey the importance of the audio cassette to my niece? She's used to iTunes, YouTube, Spotify, and goodness knows what else. I remember cassettes...

BoardSurfers: Easier Design Work Through Colors, Patterns, and Visibility

By Tyler | 4 Jun 2019

PCB and IC Package substrates these days are complex. Multiple layers, hundreds to thousands of components and pins, degassed and cross-hatched shapes, routing, and everything in between can make the visual depiction of your layout imposing, to put it mildly. How, then, do you reclaim control? Focus on exactly what you need to see and when you need to see it? Are there ways to simplify determining whether the via you...
