WASM? Well, if I'm going to tilt at windmills, I'll use the project to learn Rust while I'm at it. Explosive? I remain unconvinced. There just aren't enough people doing that kind of work. I am excited to see progress in open source FPGA fitters. I've always felt those would be hard to do because without access to the performance model, it is hard to do a good job of auto-placement. So that is cool, even though the current open source tool (I forget the name...) only does a few FPGAs.

If an open source tool exists, people will end up playing with it. That's categorically not the same of closed source tools - as social creatures we want to share what we're doing, so if we can't share that we stumbled on a cool closed-source tool leaked on the internet, what's the point of playing with it? So there's that. I would very much like to hear about your progress on this, FWIW. Also, I'm not sure, but just in case the following things I was reminded of are directly/indirectly useful/helpful (for ideas or parts, or maybe some of the engineers may be interesting to talk to..?)... - MARSSx86 - a cycle-accurate x86 emulator built on top of QEMU: http://www.marss86.org/~marss86/index.php/Home http://www.marss86.org/~marss86/index.php/Home - Cling - a C++ interpreter built on top of LLVM's JIT: https://root.cern.ch/cling https://root.cern.ch/cling There are several cycle-accurate emulators out there, MARSSx86 is the first I discovered. I'm not sure if it's useful. I'm not entirely sure why I'm mentioning Cling. It used to be based on a custom runtime (and called CINT) that was absolutely massive and was basically its own C++ implementation. Cling is effectively a very small patch/driver on top of LLVM's C++ implementation and its JIT runtime.
