How do you choose an embedded operating system—and do you even need one? Mentor’s Colin Walls looks at the options, and the reason why there are no simple answers.

Cadence’s Richard Goering has evidence that Facebook is gaining in popularity for engineer. He’s not the first person to recognize this shift, but the big unanswered questions are, ‘What’s the average age of those users and where are they located?’

ARM’s Diya Soubra introduces a new concept—personal body area sensor network. But there’s a nagging question behind this about whether people will buy into this concept or shy away for fear of having their biometric data hacked.

Mentor’s Dennis Brophy, wearing his Accellera standards hat, points to the Unified Coverage Interoperability Standard for verification coverage data. If you’re spending too much time on verification, there’s a link to download the latest standard. If you’re not spending much time, there are a lot of people who want to share your secrets—or avoid your products.
