They describe it as HLS, and it definitely looks like HLS to me. But maybe we have different definitions. Either way, it seems to be targeting a strange subset of problems: it doesn't look high level enough to be easy to use for non-hardware designers (I don't think this goal is achievable, but it is at least a worthy goal), and it doesn't seem low-level enough to allow predictable performance.
