 Finally, it is interesting to compare the performance of \vericert{} compared to existing HLS tools, to see how correctness guarantees affect the size and speed of the final hardware.  This was done on a common compiler benchmark called PolyBench/C~\cite{polybench}.

 \section{Improvements to \vericert{}}
 
 There are many optimisations that need to be added to \vericert{} to turn it into a viable and competitive HLS tool.  First of all, the most important addition is a good scheduling implementation, which supports operation chaining and properly pipelining operators.  Our main focus is trying to implement scheduling based on system of difference constraint~\cite{cong06_sdc}, which is the same algorithm which \legup{} uses.  We have currently implemented the scheduling algorithm, as well as a simple verifier for the translation, but are missing the semantic preservation proofs that the verifier should produce.
