Spice circuit simulation remains the backbone of IC design validation. Digital cell library developers rely upon Spice for circuit characterization, to provide the data for Liberty models. Memory IP designers utilize additional Spice features to perform statistical sampling. Analog and I/O interface designers extend these… Read More

For decades, tracing back to the days of Deming, the way to tackle complex engineering problems has been the pareto chart. Charting conditions and their contribution to the problem leads to mitigation priorities.

In the case of SoC power management, the old school pareto chart said the processor core was the biggest power hog and… Read More

How much power does a system consume? The simplistic path to power estimation for a system used to be tossing a few metrics – standby, typical, worst case, with figures pulled from a datasheet, simulation, or physical measurement – into a spreadsheet. After filling the remaining holes with SWAG (scientific wild-ass guesses), … Read More


How to meet 3Ps in 3D-ICs with sub-20nm Dies?

How to meet 3Ps in 3D-ICs with sub-20nm Dies?
by Pawan Fangaria on 03-06-2014 at 1:30 am

It feels to be at the top of semiconductor technology by having dies with high density of semiconductor design at sub-20nm technology node stacked together into a 3D-IC to form a complete SoC which can accommodate billions of gates. However there are multiple factors to be looked at in order to make that successful amid often conflicting… Read More
