    Project mention: C Is Not a Low-Level Language (2018) | news.ycombinator.com | 2026-09-07

    I've never done verilog professionally but I did "Digital Design and Computer Architecture, RISC-V Edition: RISC-V Edition" as an exercise 2 years ago.

    I would say Verilog is very much NOT a low level language.

    Metaphorically, it feels closer to SQL to me. I mean this in that you theoretically tell the system what it should do, and it builds it into the messy real world. However, the reality is that the planner (sql) or linker/placer/router/whatever (verilog) are very good, but you often end up needing to actually fully understand the problem anyway when things don't work in the abstract.

    I know there is https://clash-lang.org/ for Verilog design, which sounds a little like what you are talking about (never really looked at it myself).
