I think the article author is mixing up HLS tools and HDLs. HLS tools convert some subset of C to a hardware implementation, and thought that Chisel/SpinalHDL were converting Scala to hardware. But they are really just HDLs implemented as a DSL within Scala, much like Migen uses Python but does not execute Python code on the FPGA.

Yeah, I definitely jumbled both in the same basket. I should rename that into "higher-level languages" and introduce both HLS and HDL there. Thanks for the feedback, I'll make some changes to clarify my thoughts!
