Formally Verifying a Programmable Network Switch
Abstract
dc:description.abstractProgrammable network switches are complex pieces of hardware that leverage nonobvious optimizations such as pipelining to offer flexible configuration interfaces. In this thesis, we propose a novel formal-verification methodology aimed at establishing strong correctness theorems for synthesizable hardware designs for network functionality, demonstrated through a case-study analysis of a Tofino-like programmable switch that we call VeriSwit. Our approach hinges on modularity, whereby the system is split into interconnected units, each equipped with its specification and proof, oblivious to the internals of other units. We conduct VeriSwit’s modular verification in the Coq theorem prover. Experiments with synthesis for both FPGA and ASIC targets, combined with simulation, show that 100 GB/s line rate is easily achieved.
