Engineer Steve Weir Has Passed Away


Reading time ( words)

We’re sad to report late-breaking news that independent engineering consultant Steve Weir has died. No details are available at this time.

Steve was a power and signal integrity guru with a variety of patents to his name. A fixture of DesignCon and a constant presence on the SI-List signal integrity forum, Steve wrote over a dozen papers on power integrity. 

He also had a crazy, irreverent sense of humor that you don’t find among most engineers. I first met Steve about 10 years ago at DesignCon. He introduced me to a few other EEs, with caveats such as, “John’s an SI engineer, but more importantly, the statute of limitations has run out on his unprosecuted felonies. And don’t let him near your wife. Or your son, for that matter.”

It was like that with Steve. He didn’t seem to have a pause button. The world needs more people like that.

He will be missed.

AltiumLive 2022: Power and Signal Integrity—Return to Sender

02/23/2022 | Andy Shaughnessy, Design007 Magazine
I recently spoke with Heidi Barnes and Stephen Slater, both engineers with Keysight Technologies, about their presentations at this year’s virtual AltiumLive. They discussed ways to avoid signal and power integrity challenges later by following simple board design practices early on, how SI and PI are interconnected, and why the return path must be more than an afterthought in high-speed designs.

A High-Voltage PCB Design Primer

01/12/2022 | Zachariah Peterson, NWES
Of all the different boards a designer can create, a high voltage PCB design can be complicated and requires strict attention to safety. If not laid out correctly these boards can be safety hazards or can fail to function on first power up, leaving a designer with wasted time and effort. In the best case, the board will function reliably for a long period of time thanks to correct layout practices. High-voltage PCB design can be as complex as any high-speed digital design. Boards for high-voltage systems can be space constrained and they carry important safety requirements. They also need to be highly reliable to ensure they will have a long life when run at high voltage and current.

Alternatives to Simulation

We are living in an age where the demands on electronic product designs are constantly evolving. The IC technology and operating speeds continue to pose significant challenges for teams as they work to develop their products. The increased transistor switching speeds and less forgiving compliance standards make signal integrity and electro-magnetic compliance more difficult to achieve. The status quo seems to have become, “We expect to fail EMC testing.”
