This work presents a study about FPGA interconnections and evaluates
their effects on voltage-mode binary and quaternary FPGA structures.
FPGAs are widely used due to the fast 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. The use of multiple-valued logic allows
the reduction of the number of signals in the circuit, hence providing a
mean to effectively curtail the impact of interconnections. The most
important characteristic of the results are the reduced fanout, fewer
number of wires and the smaller wire length presented by the quaternary
devices. We use a set of arithmetic circuits to compare binary and
quaternary implementations. This work presents the first step on
developing quaternary circuits by mapping any binary random logic onto
quaternary devices.
