13. www.nanocmos.ac.uk Objectives  Understanding and forecasting the behaviour, characteristics and variability of next generation nano-CMOS devices using Grid-enabled statistical 3D numerical simulations;  Developing compact model and parameter extraction strategies to capture new device characteristics and variability (based on physical device simulation and early research devices), creating efficient databases for circuit design;  Developing hybrid, Grid based device/circuit simulation techniques applicable to novel nano-CMOS devices with significant variability;  Investigating the impact of new device architectures and device variability on well established design components, sub-systems and systems presently designed using conventional MOSFET architectures;  Developing novel design concepts that cope with increased variability, using specific properties of the new devices;  Learning how electronics researchers can use e-Science technologies to support their work, improve their productivity and enable them to undertake research hitherto impossible.

14. www.nanocmos.ac.uk The Development Challenge Electronic design teams currently use different tools, have different data formats, need access to large scale compute resources, generate vast amounts of data, work independently of device engineers. We are building an integrated Grid infrastructure which will revolutionise nanoCMOS design by hiding the complexity of the statistical design making it a completely integrated collaborative process.
