Cell assignment in hybrid CMOS/nanodevices architecture using Tabu Search

摘要

A recent advancement in VLSI that drastically improved the circuit density is the introduction of CMOL (CMOS/nanodevices hybrid), which consists of an overlay of a nanofabric over a CMOS stack. Combinational logic in CMOL is implemented from a netlist of NOR gates and Inverters by programming nanodevices placed between overlapping nanowires. The length of the nanowires is restricted, and therefore connectivity of the circuit elements is constrained to be within a certain radius, else additional buffers are required.
