Most of us think about capacitors the way a chef thinks about salt – knowing that it’s never the star of the show, having a keen awareness that you need just the right amount, being vaguely conscious of the fact that there are multiple, subtly different types… When we’re debugging our board, there are often times when something mysteriously isn’t working right. When all … Read More → "Aggressive with Passives"
We’ve blissfully led separate, siloed lives for years. IC designer? Someone’s having trouble routing from your pads? “Not my problem.” Package designer? Electricals on a particular signal are sketchy? “Not my problem.” PCB designer? Someone doesn’t like that the drive on an output isn’t high enough to drive your signal? “Not my problem.” It’s so much easier when you have a restricted scope, and … Read More → "Tools for Advanced Packages"
“Most people think glamour is happiness.” – Peter Falk
They say sex sells, maybe even in the MCU business. Once found only in dull products like coffee makers, washing machines, and industrial tools, microcontrollers (MCUs) are now in flashy and exciting products like… coffee makers and washing machines. What’s different now is that those embedded systems are a lot more glamorous, sexy-looking, and consumer-oriented than … Read More → "Add Glamour to Your Product"
There’s no question that the IC side of the EDA world gets most of the attention. After all, quad-patterning, EUV-having, boundary-pushing, 5-nm lithography issues are certainly bright shiny objects to grab the attention of tech-nerds. But the vast majority of us are doing more pedestrian stuff – designing board-based systems for a wide variety of applications across a huge number of end markets. What about our tools? … Read More → "Boards to Systems"
It’s almost obvious that this would be a problem. Well… part of it is obvious; part not so much.
What do accelerometers do? They measure acceleration – including periodic acceleration, more commonly known as vibration. Any vibration within the designed frequency range is subject to detection.
And what is the most prevalent kind of vibration? Sound. And what’s one really popular way to enjoy … Read More → "Cracking a WALNUT"
Over the last couple of months, there have been two interesting news items emanating from Mentor Graphics (now officially part of Siemens). They’re largely unrelated to each other, one dealing with system design and the other with IC emulation. We’ll take them in order of announcement.
A System Vision
The first story comes from their SystemVision side of things (one aspect of … Read More → "A Mentor Announcement Duo"
