FPGA structures are widely used due to early time-to-market and reduced non-recurring engineering costs in comparison to ASIC designs. Interconnections play a crucial role in modern FPGAs, because they dominate delay, power and area. Multiple-valued logic allows the reduction of the number of signals in the circuit, hence can serve as a mean to effectively curtail the impact of interconnections. In this paper, the authors propose a new FPGA structure based on a low-power quaternary voltage-mode device. The most important characteristics of the proposed architecture are the reduced fanout, low number of wires and switches, and the small wire length.
