apio is a python package you drive from the command line. I didn't know somebody had done an integration with Atom. I've installed and used apio on my phone. I wouldn't really recommend doing that, but it shows what's possible.

USB_C_Industrial_Camera_FPGA_USB3
Source and Documentation files for USB C Industrial Camera Project, This repo contains PCB boards, FPGA , Camera and USB along with FPGA Firmware and USB Controller Firmware source.
Project mention: Barcelona Supercomputing Center presents Sargantana: new open-source RISC-V chip | news.ycombinator.com | 2023-12-14>Likely you couldn't even go back and make a fab that makes large volumes of 60nm-90nm node sizes at all, for any amount of money, because the equipment to do this (new) hasn't been made in 2 decades and no company is willing to invest the money to make new crappy old equipment.
I believe your argument assumes that there is a fixed cost to produce even 180nm or 350nm ICs that hasnt changed since the first one was produced.
We still need 300 years for a 300 year old tree, but 25 year old technology might now be relatively easy to build if we start from scratch.
What was high tech then might be relatively easy to solve now. One example might be https://github.com/circuitvalley/USB_C_Industrial_Camera_FPG... being open source instead of a multi year, multi million dollar project.

The reality is that the vast majority of these FPGA-based clones don't actually perfectly emulate the logic. They're using the same reverse engineering techniques the traditional emulator developers used and sometimes even the same community documentation. The results are often quite good, but they're making a new implementation that matches the observed behavior of the original system to the best of their abilities.
Now there are some exceptions. Nuked MD FPGA[0] is a recent example of an FPGA recreation that is a fairly direct translation of the original logic using silicon die analysis. In this case, the logic is basically identical, but as you guessed the physical layout is different. Generally speaking, you write FPGA "gateware" in a language like Verilog or VHDL. These don't intrinsically have any information about the physical layout of the logic which is handled by the toolchain instead. As wmf says, this is generally not a problem most of the time. For synchronous logic, either the total propagation delay is small enough for a single cycle or it isn't. The toolchain will estimate this delay and report whether you met timing or not for the configured clockspeed.
Not everything you can do in silicon translates well to FPGAs (both clock edges is also generally not well supported for instance), but for the most part these things are easy enough to work around.

I have built a lot of open-source C++ tooling for design verification. You can find a lot of my C++ models posted on my Github. Example C++ models include: UART, SPI/DSPI/QSPI Flash, SD-Card (SPI-based interface), VGA Video, Ethernet MDIO, PS/2 mouse, OLED display, SDRAM and more. (I've even simulated PLLs using C++ models ...) I have also written extensively about doing so at ZipCPU.com.

FPGA-SDcard-Reader
An FPGA-based SD-card reader to read files from FAT16 or FAT32 formatted SD-cards. 基于FPGA的SD卡读取器,可以从FAT16或FAT32格式的SD卡中读取文件。

Wow, https://github.com/dan-rodrigues/icestation-32 looks cool. Sorry for the comment spam. :)
