4th European Workshop on CMOS Variability

Karlsruhe, Germany, September 9-11, 2013 



VARI 2013 is the 4th European Workshop on CMOS Variability. The increasing variability in CMOS transistor characteristics, as well as its sensitivity to environmental variations has become a major challenge to scaling and integration. This leads to major changes in the way that future integrated circuits and systems are designed. Strong links must be established between circuit design, system design and device technology.

The VARI workshop answers to the need to have an European event on variability in CMOS technology development and circuit design, where industry and academia meet. VARI objective is to provide a forum to discuss and investigate the CMOS process and environmental variability issues in methodologies and tools for the design of current and upcoming generations of integrated circuits and systems. The technical program will focus on performance and power consumption as well as architectural aspects like adaptability or resilience, with particular emphasis on modeling, design, characterization, analysis and optimization in respect to variability. Digital, Analog, Mixed Signal and RF circuits are within VARI scope.

The venue of VARI 2013 will be the Karlsruhe Institute of Technology (KIT), Germany. This year, VARI 2013 will be collocated with PATMOS 2013, a reference workshop on Power and timing modeling, optimization and simulation.

Prospective authors are invited to submit an A4 camera ready paper, no later than June 7th 2013, including a 100-word abstract, figures and references, not exceeding 6 pages or 5000 words. Electronic submission is required and should follow the IEEE double column style, for the final publication. Submitted papers will be reviewed formally by several reviewers. Accepted/Invited papers will be included in the PATMOS-VARI conference proceedings.

Selected papers will be included in a special issue of The Journal of Low Power Electronics (JOLPE).

Student Papers presented at the conference will be considered for the Best Student Paper Award. The award delivery will take place at the closing session of the workshop.
