chipyard

5 1,411 9.7 C

An Agile RISC-V SoC Design Framework with in-order cores, out-of-order cores, accelerators, and more

Project mention: Chisel: A Modern Hardware Design Language | news.ycombinator.com | 2023-12-27

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.

Woof! is a continuation of the Boom/MBF bloodline of Doom source ports. (by fabiangreffrath)

Project mention: A newcomer to Doom. | /r/Doom | 2023-05-28

Check out Woof! to see a more conservative but still enhanced port of Doom, and imp it runs even smoother than GZDoom. The spirce port really can impact the feel of the game.
