   Abstract : The awareness of the threat posed by Lightning Electromagnetic Pulse (LEMP) and High Power Microwaves (HPM) against the operational reliability of electric systems is rapidly growing. This has led to an increasing need for reliable tools, experimental as well as theoretical, for design, analysis and verification of system immunity against electromagnetic threats. READ MORE

5. 3. Manufacturability in the Nanometer Era: Regularity considerations in VLSI Circuits

   Author : Kasyab Parmesh Subramaniyan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Regular Fabrics; Shifters; Barrel Shifter; ASIC; TDM; Bricks; Wired; Transistor; VLSI.; Multipliers; CMOS; HPM; Regularity; SoC; Arithmetic; Circuits;

   Abstract : Each reduction of the technology node has, along with improvements in IC fabricationtechnology, been the main driver in delivering the demand for function rich, integratedmobile electronics that are so prevalent. As devices keep growing smaller and geometriesapproach the order of a few atomic layers, it is increasingly difficult to achievecost-effective mass production for reasons related to performance and fabrication capability.
