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)"

A Tale of Two Spectrum Analyzers

“Don’t look back. Something might be gaining on you.” – Satchell Page

Dave Jones, the multitalented proprietor of EEVblog.com has posted more than 1100 online videos covering all aspects of electronics, including numerous teardown videos that I used frequently in a prior life to highlight certain revealed design aspects in the equipment he’s torn down. Recently, Jones posted a 1-hour (!) teardown … Read More → "A Tale of Two Spectrum Analyzers"

Decoding Silicon Valley

“Silicon Valley is not a magical place, but magical things happen there.” – Jonathan C. Baer

Earlier this week, more than 100 engineering consultants, a few marketers, and four mad scientists (self-proclaimed “consulting physicists”) met under the auspices of the IEEE-CNSV—that’s the Consultants’ Network of Silicon Valley—to schmooze, eat Stuft pizza, and hear serial … Read More → "Decoding Silicon Valley"

DVCon and the Big Data Problem

Design and verification technologies are front and center in this week’s episode of Fish Fry. DVCon General Chair Dennis Brophy joins us with a special sneak peak of the 2018 Design and Verification Conference. Dennis and I chat about how the biggest trends are reflected at DVCON, including machine learning, automotive technologies, and big data analysis. We also discuss the addition of shorter format workshops to … Read More → "DVCon and the Big Data Problem"

Security: Hard and Soft

“We will bankrupt ourselves in the vain search for absolute security.” – Dwight D. Eisenhower

I hate writing about security. I hate it because I wish it were unnecessary. There was a time when engineering meant making a product that did what you wanted it to do. Now it means spending a bunch of time making it not do what other people want but … Read More → "Security: Hard and Soft"

Let'€™s face it: We'€™re addicted to SRAM. It'€™s big, it'€™s power-hungry, but it'€™s fast. And no matter how much we complain about it, we still use it. Because we don'€™t have anything better in the mainstream yet. We'€™ve looked at attempts to improve conven...

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"
