TNG of DFT

Most people are familiar with the TNG concept, which sprang from the original Star Trek TV series being rebranded as “Star Trek: The Original Series” when its shiny successor “Star Trek: The Next Generation (TNG)” appeared on the scene (no pun intended). Well, I’ve just been introduced to the next generation (TNG) of design for test (DFT).

Everything You Always Wanted to Know About SI* (*But Were Afraid to Ask)

The Man, The Myth, The Legend of Everything SI – the one and only Dean of the Teledyne LeCroy Signal Integrity Academy Eric Bogatin joins Fish Fry this week. I had the pleasure of sitting down with Eric at this year’s AltiumLive and we talked about a wide variety of signal and power integrity issues including the downsides of open source designs, what signal integrity noise and rogue waves … Read More → "Everything You Always Wanted to Know About SI* (*But Were Afraid to Ask)"

Instrumenting the Internet of Really Big Things

“I like to rattle cages.” – Viv Albertine

Noise, vibration, and harshness. In the automotive world, NVH is a bad thing. There are specialist NVH engineers at most carmakers laboring away to exorcise mechanical gremlins.

But not all NVH is bad. In the industrial world, we can steer those gremlins toward good. We can even – if we’ … Read More → "Instrumenting the Internet of Really Big Things"

Pimping My Variac Autotransformer (Actually, it’s a Philmore)

It seemed like such a good idea at the time.

I’ve wanted an autotransformer for electronic troubleshooting work for a while. Autotransformers are variable transformers that let you bring the AC voltage up slowly on a piece of gear under test. I owned a Radio Shack/Micronta variable transformer for decades, but it didn’t survive my move to … Read More → "Pimping My Variac Autotransformer (Actually, it’s a Philmore)"

Innovative Hybrid Crowbar Protection for AC Power Lines — Littelfuse and Mouser Electronics   Providing robust AC line protection is a tough engineering challenge. Lightning and other unexpected events can wreak havoc with even the best-engineered power supplies. In this episode of Chalk Talk, Amelia Dalton chats with Pete Pytlik of Littelfuse about innovative SIDACtor semiconductor hybrid crowbar protection for AC power lines, that combine the best … Read More → "Innovative Hybrid Crowbar Protection for AC Power Lines — Littelfuse and Mouser Electronics"
IoT and The Power of PSpiceToday's IoT designs demand some complex mixed-mode, mixed-signal simulation to be sure that they'll work correctly across wide ranges of component variation, temperature, and other real-world conditions. In this episode of Chalk Talk, Amelia Dalton chats with John Carney of Cadence Design Systems about PSpice mixed-signal simulation for IoT.
SystemVision® Multi-discipline System Verification DatasheetThe SystemVision multi-discipline collaboration environment lets you explore concepts, validate performance specifications, investigate architectural partitions, and integrate implementation-level details, all in an easy-to-use virtual prototyping environment. Focus on a single design domain, or combine multiple domains, for full-system verification.
Reduce Project Schedules and Increase Quality using Model Driven Development for Design, Verification, and TestThis paper shows how Model Driven Development can address common challenges in the system design, verification & testing of complex systems. Project success requires that hardware, software, and test teams fluently integrate application software, controlling firmware, analog and digital hardware, and mechanical components, which often proves to be costly in terms of time, money, and … Read More → "Reduce Project Schedules and Increase Quality using Model Driven Development for Design, Verification, and Test"
Concept to X: Ten Steps to Effective Model Driven DevelopmentModel Driven Development is proven to improve productivity in the design process. It makes it possible to use models all the way down the flow, automatically generating parts of the design and thus improving the design’s quality by bringing in repeatability and standards compliance. It enables actions such as eliminating physical prototypes from the process, … Read More → "Concept to X: Ten Steps to Effective Model Driven Development"
