A novel approach to testing lookup table (LUT) based field programmable gate arrays (FPGAs) is proposed in this paper. A general structure for the basic configurable logic array blocks (CLBs) is assumed. We group k CLBs in the column into a cell, where k denotes the number of inputs of an LUT. The whole chip is configured as a group of one-dimensional(More)
This paper analyzes the deposition defects in devices and circuits made of Quantum-dot Cellular Automata (QCA) for molecular implementation. Differently from metal-based QCA, in this type of implementation a defect may occur due to the erroneous deposition of cells (made of molecules) on a substrate, i.e. no cell, or an additional cell is placed either(More)
Mixing of complementary tree species may increase stand productivity, mitigate the effects of drought and other risks, and pave the way to forest production systems which may be more resource-use efficient and stable in the face of climate change. However, systematic empirical studies on mixing effects are still missing for many commercially important and(More)
Emerging technologies have attracted a substantial interest in overcoming the physical limitations of CMOS as projected at the end of the Technology Roadmap; among these technologies, quantum-dot cellular automata (QCA) relies on different and novel paradigms to implement dense, low power circuits and systems for high-performance computing. As applicable to(More)
At nanoscale, quantum-dot cellular automata (QCA) defines a new device architecture that permits the innovative design of digital systems. Features of these systems are the allowed crossing of signal lines with different orientation in polarization on a Cartesian plane, the potential of high throughput due to efficient pipelining, fast signal switching, and(More)
There has been considerable research on quantum dot cellular automata (QCA) as a new computing scheme in the nano-scale regimes. The basic logic element of this technology is majority voter. In this paper, a detailed simulation-based characterization of QCA defects and study of their effects at logic-level are presented. Testing of these devices is(More)
This paper addresses the issues revolving around the synthesis of tile sets for DNA self-assembly as a promising approach for IC manufacturing in the nanoscale. As for a finite pattern, synthesis for minimizing tile or bond types is equivalent to a minimum graph coloring problem, two greedy algorithms that reduce the number of tiles (PATS_Tile) or bonds(More)
