Abstract : For advanced technology nodes, static consumption of integrated circuits has become a key factor for the microelectronics industry. Circuit energy efficiency is measured in terms of performance and static consumption. With the increase of physical and environmental parameters, the Fully-Depleted Silicon-on-Insulator technology allows to extend Moore's law in the nanometer domain. In this work, a statistical study of CMOS-FDSOI integrated circuit energy is carried out. Statistical libraries characterizing delay and static power of CMOS-FDSOI transistors are presented. Given the advantages of the FDSOI technology, statistical approaches based on the libraries are applied in order to estimate delay and static power. While maintaining the accuracy of the estimations, these approaches provide a significant gain in CPU time. Following delay and static power estimation, CMOS-FDSOI transistors energy variations are considered according to supply voltage and voltage body biasing. Thus, by determining an efficient Delay-Static Power compromise and the development of a statistical optimization flow, static energy of a circuit has been optimized.
