(verilog flow from https://github.com/H-S-S-11/tinytapeout-verilog-test)

This design shows a simple SRLLUT cell, allowing the LUT configuration to be programmed via a traditional frame configuration (the shift register would be shared across the entire die, and the multi-bit frames loaded in parallel for each row/column of the configuration). Then at runtime some dynamic logic trickery to "freeze" an intermediate value inbetween latches allows the LUT to be used as a shift register, like a certain Big Red Company's FPGAs have since time immemorial.

The Verilog flow is:

1. Fork this Repo
2. Create a wokwi project to get an ID
3. Update WOWKI_PROJECT_ID in Makefile
4. grep -rl "341154068332282450" ./src | sed -i "s/341154068332282450/YOUR_WOKWI_ID/g" from the top of the repo to find and replace all occurences of the old ID in src with yours, and rename the user_module, user_module_tb and scan_wrapper files to use your ID
5. Replace behavioural code in user_module_ID.v with your own, likewise change the testbench
6. Push changes, which triggers the GitHub Action to build the project
