Many <i>facts</i> about emerging nanotechnologies are yet to be assessed. There are still major concerns, for instance, about maximum achievable device density, or about which architecture is best fit for a specific application. Growing complexity requires taking into account many aspects of technology, application and architecture <i>at the same time</i>.(More)
Among the emerging technologies Field-Coupled devices like Quantum dot Cellular Automata are one of the most interesting. Of all the practical implementations of this principle NanoMagnet Logic shows many important features, such like a very low power consumption and the feasibility with up-to-date technology. However its working principle, based on the(More)
In most computational systems memory access represents a relevant bottleneck for circuits performance. The execution speed of algorithms is severely limited by memory access time. An emerging technology like Nano Magnet Logic (NML), where its magnetic nature leads to an intrinsic memory ability, represents therefore a very promising opportunity to solve(More)
Nano-Magnetic Logic (NML) is a promising candidate to substitute CMOS technology since it is characterized by very low power consumption and it can combine computation and memory in the same device. Several works analyze this technology at device level; nevertheless a higher level analysis is required to fully understand its potentials. It is actually(More)
NanoMagnet logic (NML) is among the emerging technologies that might replace CMOS in the next decades. According to its physical characteristics, to better exploit the potential of this technology—and of other similar ones—the use of parallel architectures with regular layout that avoid long interconnection signals is advised. Systolic arrays (SAs) are(More)
In the post-CMOS scenario, field coupled nanotechnologies represent an innovative and interesting new direction for electronic nanocomputing. Among these technologies, nanomagnet logic (NML) makes it possible to finally embed logic and memory in the same device. To fully analyze the potential of NML circuits, design tools that mimic the CMOS design-flow(More)
Perpendicular Nanomagnetic logic (pNML) is one emerging beyond-CMOS technology listed in the ITRS roadmap for next-generation computing due to its non-volatility, monolithic 3D-Integration, small size scalability and low power consumption. Here, we demonstrate the feasibility of a monolithic 3D pNML circuit, which is capable of integrating both memory and(More)
We automatically maximize fault-tolerance in nanoarrays based on silicon nanowires and Gate-All-Around transistors optimizing their topology vs. several distributions of faults inherited by technology. We added a MonteCarlo engine in our nanoarchitecture design tool ToPoliNano and verified the effectiveness of the fault-tolerance algorithm over several(More)
The post-CMOS scenario poses many challenges to researchers. Innovative solutions must be found to further improve electronic circuits. Exploiting the potential offered by the third dimension is clearly one of the best possibilities available. However, due to the lack of a simple and straightforward methodology, it is difficult to analyze and compare(More)
