Ah, the quaint old days, back when you assembled the analog and digital parts of a system out of separate components. The analog side got the analog parts … Read More → "Analog Functions Made from Digital Circuits"
A couple of years ago, we covered a company that was working to make power supplies more efficient. Today we update that story. But… if you take the company name today and try to find the old article, you’ll have a hard time: they’ve changed their name from Semitrex to Helix.

When all … Read More → "Aggressive with Passives"
OK, you’ve just been assigned a new project. There’s a cell that’s in need of Monte Carlo variation analysis. You’re looking for 6σ accuracy – 1 failure in a billion. So you run the numbers, and you find that you’re going to need 5 billion separate simulations. Yes, that’s with a “B.” No, retreating to a less aggressive node won’t help; this number is independent of … Read More → "Machine Learning Hits EDA"
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"
