Controlling Heat


Modeling on-chip thermal characteristics and chip-package interactions is becoming much more critical for advanced designs, but how to get there isn't always clear. Every chip, based on its target application, has a thermal design power (TDP) target. This is the typical power it can consume without overreaching the acceptable thermal limits in its intended environment. But in order to rate t... » read more

Thermal Issues Getting Worse


Making sure that smartphone you’re holding doesn’t burn your face when you make a call requires a tremendous amount of engineering effort at all levels of the design - the case, the chips, the packaging. The developers of the IP subsystems in that smartphone must adhere to very strict power and energy thresholds so the OEM putting it all together can stick to some semblance of a product des... » read more

Too Hot To Handle


By Ann Steffora Mutschler It used to be that a device could be designed to a thermal design power. The worst case power scenario would be imagined, and the device would be designed with that in mind. But those good old days are gone. Especially for consumer devices, how a device is going to behave with respect to time, or how people are going to use it, must be understood as completely a... » read more

Thermal On My Mind


Oh heat, how I miss thee… in the dead of winter of course. And while heat is a good thing for my garden, it’s not so great when it comes to my, your and everyone’s electronic devices. I’ve been reflecting a lot on this topic since researching thermal management for my article, “Too Hot To Handle.” You see, I have a favorite laptop. It’s a MacBook Pro with a nice, large screen a... » read more
