The new generation of multimedia-application processors requires a drastic leakage reduction to bring the standby current to 50/spl mu/A. An efficient set of leakage reduction techniques, including power gating, memory retention, voltage scaling, and dual V/sub t/, is employed on a 50M transistor, 80mm/sup 2/ IC, fabricated in a 90nm CMOS technology, resulting in a 40/spl times/ leakage reduction.
In this paper we present a leakage management system which takes advantage of the existing clock gating infrastructure. This methodology avoids both RTL and software changes, at the block and chip level. We illustrate this approach with a 65-nm digital base band modem while achieving standby leakage in the 100-muA range and overall 1200times leakage reduction including process, circuit and system optimization
At the 90-nm, leakage currents bring standby power to an unacceptable level and circuit level techniques become mandatory. However applying these techniques must be robust and practical. In this paper we focus not only on leakage reduction solutions but also on their deployment as a worldwide infrastructure as the added-value resides not only in the techniques themselves but also in the way they are implemented to build an efficient, re-usable, robust, low cost and portable platform. Techniques have been silicon proven on the 90-nm TI CMOS technology and is commonly used to design SoC with complexities over 100 Million transistors.

Methodology, EDA Flow, scripts, and documentation plays a tremendous role in the deployment and standardization of advanced design techniques.
