OpenROAD

KiCAD might not be a great example, but you could with something like https://github.com/The-OpenROAD-Project/OpenROAD (or roughly along those lines - I'm not a hardware person), no? The parent's question still seems applicable. Is this basically down to a judge to decide the line at which a certain technology is too advanced to export? Would open sourcing an EDA tool be illegal if it was sufficiently capable?

OpenROAD comes to mind, as the main open source self optimizing RTL-to-GDS effort. Begat in part with DARPA help. Lots of derivarive efforts/projects! There was a ton of energy & hype & visibility for the first couple years after launch (2018). But it's been pretty quiet, a lot less PR since. I wish there was more visibility into the evolution of this & related effort. https://github.com/The-OpenROAD-Project/OpenROAD?tab=readme-...

I should note there's open source ASIC toolchain - OpenROAD[1][2]. I wonder if these can be integrated. You also can use SymbiFlow to run your prototype in FPGA[3][4].
