    Chisel: A Modern Hardware Design Language (by chipsalliance)

    Project mention: Calyx: Intermediate Language for Hardware Accelerators | news.ycombinator.com | 2024-02-26

    My first instinct was to ask "Does this play well with CIRCT?" And thankfully they answer that right away in the README.

    I'm personally of the opinion that there is a LOT of room for improvement in the hardware design tooling space, but a combination of market consolidation, huge pressure to meet deadlines, and an existing functional pipeline of Verilog/VHDL talent is preventing changes.

    That's not to say "Verilog/VHDL are bad", because clearly they've been good enough to support nearly all of the wonderful designs powering today's devices. But it is to say, "the startup scene for hardware will continue to look anemic compared to the SaaS scene until someone gives me all of the niceties I have for building SaaS tools in software."

    A huge amount of ideas (and entire designs) start off as software sims, which enables kernel/compiler engineers to start building out support for new hardware before it's manufactured.

    There is some interesting work going on at SiFive building hardware with Chisel[1], as well as some interesting work lead by a professor at William and Mary to improve simulations[2].

    It's probably true that Chisel isn't right for industry -- Google tried it too for the TPU project and eventually went back to Verilog. That said, I think it's main win is that it is great from a research / open-source perspective.

    Taking advantage of the functional nature of Chisel enables a set of generators called Chipyard [0] for things like cores, networking peripherals, neural network accelerators, etc. If you're focusing on exploring the design space of one particular accelerator and don't care too much about the rest of the chip, you can get a customized version of the RTL for the rest of your chip with ease. All the research projects in the lab benefit from code changes to the generators.

    Chisel even enables undergraduate students (like me!) to tape out a chip on a modern-ish process node in just a semester, letting Chisel significantly reduce the amount of RTL we have to write. Most of the remaining time is spent working on the actual physical design process.
