    High-Speed Design Techniques: Trace Tuning for Routing Length Matching The first time I heard someone talking about “tuning” their high-speed PCB design, the memory of my middle school band came to mind. Back in those days, “tuning” meant taking kids who lacked experience and who used tired old instruments and trying to turn it all into something that blended together. As you would expect, our first attempts at being in tune were not very successful. After some work, though, we were able to stay in tune together Read Article
    How Multi-Level BOMs Can Organize Your Next System Design If only packing for vacation were as simple as it sounds: figure out what clothes you need, throw them in a suitcase, and you’re ready to go—wrong! Here’s the more realistic vacation planning scenario: pack your clothes, pack your children’s clothes, and then pack all the other personal necessities such as diapers, games, etc. Next you need to pack the food followed by whatever gear your particular vacation requires including tents, fishing Read Article
    Frank Duggan: Micro Architecture and Aspiring to MIT Judy Warner: What first got you interested in developing your own microarchitecture using discrete logic? Frank Duggan: Without really knowing the specifics, it was something I'd wanted to do since I was little. I was obsessed with my Snap Circuits electronics kit, and liked to challenge myself to build circuits that do various things. At some point, I decided that building a computer was the ultimate challenge. This was probably because I found Read Article
    Is It Hot In Here Or Is That Your PCB Shorting - Common Causes of Shortages As an undergrad, I once had classes cancelled because of an electrical fire in a neighboring building. Even funnier was that I was actually in a junior-level electrical engineering course when we were dismissed. Several students wanted to go check the fire out; their reasoning was that we were electrical engineers, and thus electrical fires fell under our purview. In this class we’d had quite a few labs ending with blue smoke (and even one small Read Article
    Internet of Things Security Best Practices: Passwords, Patches, and Portals If you’ve ever created devices for military applications you’re probably used to designing with security in mind. If you’re more like me, and just build the odd Internet of Things (IoT) doodad, that’s probably the last thing on your mind. However, recent cyber attacks are highlighting why engineers like us should be a little more concerned with security. These design best practices will show you how you can safeguard your systems. Why Secure the Read Article
    How the Right Tools in Your PCB Toolkit Can Help Your Next Design When my sons were young, it was a joy for me to introduce and show them how to use tools for repair or construction. They would ask questions about the different tools in my toolkit, and my pair of old Channellock pliers really seemed to catch their interest. To tell the truth, those Channellocks are my favorite too. I inherited them from my dad, and still use them. They’re the first tool in my kit that I look for when I need to solve a problem Read Article
    Internet of Things Security Issues Prompt Government Intervention When you look at an Internet of Things (IoT) device like a fork or a juicer, what do you see? Like me, you probably see a gadget that was designed for a particular purpose. Less upstanding citizens may see a digital weapon instead of an innocuous gizmo. In the past several years, there have been several high-profile distributed denial-of-service (DDoS) attacks that were enabled by poorly-secured IoT devices. Hackers infiltrate light bulbs and Read Article
    Introduction to High Speed PCB Designing: Signal Paths Have you ever planned an airline trip where there isn’t a direct flight to get you to your destination? I have, and as you probably already know, it isn’t a problem. I use the travel planner on my airline’s website and let it figure out every detail of the trip for me. All I have to do is plug in my origin and destination, and the planner determines my itinerary—with enough time to make my connections. It’s a piece of cake. Can you imagine how Read Article
    Tips for Real-World PCB Design: Timing, Communication, and Traceability I love food; I love the preparation, finding the ingredients, adding the minute adjustments of seasonings and salt, and cooking multiple courses at once. But when I first started cooking for myself, I prepared each part of the meal individually. I found it immensely difficult to keep track of the different dishes and ensure none stuck to the pan—or went without stirring for too long. So I sacrificed time and did each task individually. What my Read Article
    The Best Flash Memory Storage Solution: Is NOR or NAND Ideal for Your Project? I must admit that I’m pretty ignorant when it comes to wine: should I get a white wine for my dinner date, or would a red be more appropriate? And don’t test me on the differences between different whites or different reds. I know that there are some guidelines for which variety to pair with various foods and flavors, but I have no idea what these recommended pairings are. Just like red and white wines, NOR flash and NAND flash memory storage Read Article
