With applications ranging from fields as distinct as fuzzy modeling (Xiong 2001), autonomous robot behavior (Luk et al. 2001), learning with backpropagation (Foo et al. 1999), and multicriteria optimization (Viennet et al. 1996), evolutionary methods have become an indispensable tool for systems scientists. Although already studied in the past, an interesting emerging issue is the use of multip...

the full adders (fas) constitute the essential elements of digital systems, in a sense that they affect the circuit parameters of such systems. with respect to the mosfet restrictions, its replacement by new devices and technologies is inevitable. qca is one of the accomplishments in nanotechnology nominated as the candidate for mosfet replacement. in this article 4 new layouts are presented fo...

This paper presents a computer-aided design tool, IPRAIL, which automatically retargets existing analog layouts for technology migration and new specifications. The reuse-based methodology adopted in IPRAIL utilizes expert designer knowledge embedded in analog layouts. IPRAIL automatically extracts analog circuit and layout intellectual properties as templates, incorporates new technology desig...

The manufacturability benefits of restricted design style have long been recognized in the implementation of SRAM and FPGA circuits. However, the ASIC community has shied away from layout restrictions for the fear of stifling designers’ creativity and creating an inefficient area, and thus cost, product. Nevertheless, as the design features required began to approach nanometer-scale dimensions,...

The Aerospace Systems Design Laboratory at the Guggenheim School of Aerospace Engineering, Georgia Institute of Technology, has recently created the "Collaborative Design Environment" (CoDE), a nextgeneration design facility supporting efficient, rapidturnaround conceptual design. The CoDE combines cost-effective, off-the-shelf information technology with advanced design methodologies and tools...

The present study is an attempt to propose a mutation-based real-coded genetic algorithm (MBRCGA) for sizing and layout optimization of planar and spatial truss structures. The Gaussian mutation operator is used to create the reproduction operators. An adaptive tournament selection mechanism in combination with adaptive Gaussian mutation operators are proposed to achieve an effective search in ...
