“…Looking to propose more robust tools able to follow the top-bottom approach established by CMOS, [51] proposed the ToPoliNano, a tool that allows the description of NML circuits with high-level languages such as VHDL and Verilog HDL and, from that description, generates the circuit logicgate-based layout. This framework comprises two other tools: 1) MagCad and 2) ToPoliNano.…”

After the continuous development of CMOS technology driven by transistor miniaturization and Moore’s law, the scientific community is witnessing the exploration of emerging paradigms to find new ways to develop computational systems. This paper presents critical concepts for understanding some of these new nanocomputing technologies, specifically field-coupled, quantum-dot cellular automata, nanomagnetic logic, silicon dangling bounds, photonic crystal logic, and DNA computing. Next, it shows emerging design automation tools for each of these areas and how they can be applied to support the development of new computing systems. The level of maturity and production speed of solutions achieved by conventional silicon technology thanks to very efficient electronic design automation (EDA) is remarkable. However, here we are dealing with technologies still in their infancy. Therefore, improvements in design automation tools are undoubtedly a way to accelerate the growth of new substrate alternatives and modern applications.

“…Earlier clocking scheme models define partitions with sequential columns that repeat the clocking phase, ordering consistent signal propagation. Figure 8a depicts a 4-phase cutout and Figure 8b depicts a 3-phase cutout, both designed to work with combinational logic [37]. Figure 8b highlights the components of a basic cutout.…”

CMOS technology is reaching power, thermal, and physical limits at an alarming pace. As a response, post-silicon research investigates alternative technologies to perform computation. Field-Coupled Nanocomputing (FCN) presents low power dissipation, high frequencies, and room temperature operation. Nevertheless, FCN imposes several challenges in the development of efficient and scalable CAD tools. The placement and routing step is especially tricky in FCN compared to CMOS because of synchronization issues inherent to these technologies, such as path balancing and reconvergent paths. In this work, we survey the state-of-art of placement and routing algorithms for FCN. We describe the most recent FCN placement and routing algorithms, highlighting their limitations and, finally, presenting future work directions.

“…The ToPoliNano tool designs iNML circuits and performs automatic layout generation and simulation. The circuits designed and validated by the tool in the literature are predominantly combinational circuits such as the half adder [9], full adder [10], multiplexer [11], demultiplexer [12], decoder [13], ripple carry adder [14], 32 bit Pentium-4 tree-Adder [15], ISCAS 85 benchmark [16], and systolic multiplier [17]. Sequential circuits have not been designed much in iNML.…”

Bit manipulation plays a significant role in high-speed digital signal processing (DSP) and data computing systems, and shift and rotation operations are crucial functions in it. In general, barrel shifters are used to perform these operations effectively. Nano magnetic logic circuits are among the promising beyond-CMOS alternative technologies for the design of high-speed circuits. Most of the existing circuits that have been developed using nano magnets are combinational circuits. In this work, a barrel shifter is implemented and realised using in-plane nano magnetic logic. The proposed design is the first of its kind nano magnetic logic circuit. The nano magnetic logic circuit implementation, layout generation, simulation, and validation were performed using the ToPoliNano and ModelSim tools. The logical equivalent design was synthesised and evaluated using the Synopsys Design Compiler tool. The proposed barrel shifter was realised using majority logic has 1769037 nano magnets with a boxing area of 481 × 13104 µm2 and 3276 clock zones after optimisation with the Barycenter algorithm. The proposed barrel shifter realised using Boolean logic has 315276 nano magnets with a boxing area of 265 × 5028 µm2 and 1257 clock zones after optimisation with the Barycenter algorithm. The proposed design results demonstrate that complex systems can be developed using nano magnetic logic by combining combinational and sequential circuits.
