CONfigurable Transceiver Energy uSage Toolkit (CONTEST) allows the characterisation of the energy consumption of the physical layer of optical transceivers including line coding, frame alignment, channel bonding, serialisation and deseralisation, clock/data recovery and clock generation.
Power consumption of networking equipment are under increasing scrutiny, particularly as network end points are moving on-chip in the latest generation of SoC processors. Although ultra-low energy silicon photonic components have been demonstrated, these components and front end drivers only consume a small proportion of total serial transceiver power. Hence, major reductions in optical transceiver power can only be obtained with attention to the physical layer circuits of which serialisation and deserialisation are the largest component. In addition, burst mode transceivers are required both for power gating and to take advantage of future optical switching systems.
To facilitate continued work in this field we provide CONTEST, promoting direct comparison by enabling other researchers to reproduce our results thereby permitting meaningful comparison.
The toolkit contains a combination of source code files for each basic transceiver building block design (Verilog/HSpice)and a set of configuration scripts (Perl/Tcl) for stimuli generation, synthesis, simulation and power analysis using a standard CMOS technology process library.
