ToPoliNano: a CAD Tool for Nano Magnetic Logic

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 should be used for circuit design. We present, in this manuscript, the latest and improved version of ToPoliNano, our design and simulation framework for Field Coupled Nanotechnologies. ToPoliNano emulates the top-down design process of CMOS technology. Circuits are described with a VHDL netlist and layout is then automatically generated considering in-plane NML (iNML) technology. The resulting circuits can be simulated and performance can be analyzed. In this work, we describe several enhancements to the tool itself, like a circuit editor for custom design of Field Coupled Nanodevices, improved algorithms for netlist optimization and new algorithms for the place and route of iNML circuits. We have validated and analyzed the tool by using extensive metrics, both by using standard circuits and ISCAS 85 benchmarks. This contribution highlights the improvements of ToPoliNano, which is now a innovative and complete tool for the development of iNML technology.
