EEJournal, as its name implies, concentrates on the bits and bytes or the chips and boards of the electronics industry. But there are times when it seems like a good idea to look at wider issues. And this may be one of them. What has triggered this is a series of news stories that have demonstrated technology failings that have led to broader consequences.
As much as the EDA industry would like us to believe otherwise, it’s almost impossible to find an engineering team who is satisfied with their design tools. More often than not, when chatting with designers about their tools, we get sentiments ranging from “survivable” to “horrible.” The “survivable” end of the spectrum usually amounts to something on the order of, “We managed to get the … Read More → "Why Are Design Tools So Bad?"
System Design is inherently a task of integration. The job of the system engineer is to gather and integrate a collection of components which, taken together, will solve some problem, while meeting a list of requirements such as form factor, performance, functionality, power consumption, reliability, and cost.
Almost all of the components we choose will be sourced from third parties. Seldom (if ever) these days is there … Read More → "System Delta Sigma Delta"
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"
