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!)....

DATA Pulse: Know How to Effectively Manage Part Obsolescence (Part 2 of 2)

By Auromala | 2 Jul 2019

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...

DATA Pulse: Know How to Effectively Manage Part Obsolescence (Part 1 of 2)

By Auromala | 16 Jun 2019

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: Text Labels and Film Views Help Intelligent Designers

By Tyler | 11 Jun 2019

Last time, I talked about color and visibility as it relates to simplifying your design canvas display to make your work easier. Today, we take the next step forward: using your artwork films to drive what you see on screen, as well as dynamic text labels to help you find objects. We’ll close out with a reminder of how to recycle the time you’ve spent setting up one design across all your designs. Artwork Films as...

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...

BoardSurfers - Aerials and Bails: How to Hide the Design Path in Art File

By Monika | 25 Apr 2019

Before manufacturing, PCB fabricators analyze Gerber data to verify if it is manufacturable or not. If the artwork data meets the requirement, it is processed to make it usable by production tools and equipment. The various stages of data analysis and processing are automated at the manufacturer's end. Depending on the PCB maker you are working with, you may need to create artwork data files per their requirement. ...

BoardSurfers: Place Replicate to Increase IP Reuse and Decrease Design Time

By Tyler | 15 Apr 2019

Once you have successfully designed and optimized an area of your substrate today, how do you leverage your tool to reuse your work across the rest of your current design – or apply it to other similar layouts in your queue? If you have the good fortune to use the Cadence® Allegro® layout tools, you should turn to the place replicate interface. Whether you want to leverage just the symbol placement, incorporate additional...

Your design is near completion. Except that you’ve got an area of your plane shape that stubbornly refuses to fill, and you don’t know why. Understanding the rules involved and the tools available to help you figure out – and make changes, if needed, to get the result you want – is critical to make sure you aren’t wasting valuable design cycles. Thankfully, the Cadence® Allegro® platform provides you with the exact...

BoardSurfers: Dynamic Shape Voiding – Getting the Most Out of the Tool

By Tyler | 28 Mar 2019

Dynamic shapes; whether used on a negative or positive artwork layer, for power, ground, or signal; are the next most common element of a design after components and routing. The importance of using them effectively, then, can be the difference between a design that is DRC-free, ready on time, and easy to update for ECOs (Engineering Change Orders) and one that you seem to struggle with on a daily basis trying to force...

Today’s dense and complex PCB designs require realistic 3D view to investigate the design issues way before they are ready for manufacturing. The complexity of the PCB designs is increasing significantly with time and visualizing all the design components to address electronic and mechanical design issues in a single consistent environment has become a challenge. To cater to this need Cadence® Allegro® PCB Design Solutions...

Teardrops and Tapers – Improving Manufacturability and Yield Automatically

By Tyler | 13 Mar 2019

Teardrops (also called fillets) are the blending area of a cline entry into a pad, while tapers are the gradual transition from one line-width to another along a path. These two core concepts appear in nearly any PCB or IC package substrate today. They act to smoothen the intersection of the two objects, eliminating acute angle acid traps while also contributing to better signal integrity along the path. However, any...

Simulation for a Song: Downloading Models from the Web and Associating with Parts for PSpice Simulation

While on a long drive, I like to sing along; say Eye of the Tiger or Johny B Goode or Sweet Home Alabama (even though I don’t live in Alabama), the music being an active part of the journey, especially when I am just beginning the drive, fresh and eager, looking forward to the trekking and wildlife sightings. Compare this with the schematic design phase. Whistling and nodding while placing the parts: here’s the library...

How is a Multi-board PCB System Assembly Different from Rigid-Flex Assembly

By TeamAllegro | 19 Oct 2018

When people typically think of multi-board PCB design, they tend to picture racks of boards in server farms or the components of a gaming rig. But what if your typical rigid boards don’t fit within the physical envelope of your multi-board application? Do you pay a premium for flexible circuitry? What if you could have the best of both worlds?

How To Maintain Connectivity in a Multiboard PCB System

By TeamAllegro | 9 Oct 2018

By John Burkhert Jr Bringing a multiboard system together is a chance for the designer to spread their wings. As the circuit spreads, so do the risk of crossed signals. Some of the ways the circuits can get scrambled include: Some connector vendors have clear indications of polarity. Others leave all numbering to the buyer. In the same way, a row of gold fingers will be anything we draw up in terms of pin numbers...

The Day a PCB Was Born

By TeamAllegro | 3 Oct 2018

By John Burkhert Jr I want to take you back to a project that highlights a few twists as all good projects will. 17 years ago I was presented with 20 pounds of potatoes and a 10 pound bag. The bag was shaped like a PEZ dispenser with a crown of gold fingers in place of the plastic head. The actual name of the early form factor was XENPAK. It used the XAUI protocol which has become a popular 10G-for-the-masses deal...
