Error when running cocotb using cocotb-test
It is 4.106, check https://github.com/verilator/verilator/issues/2778 for more details.

Verilator: Suggestions for verification framework?
Yeah, there is currently a bug and only one specific version of verilator works with cocotb (4.106). Hopefully it will be fixed soon. Go make noise here: https://github.com/verilator/verilator/issues/2778.

Vitis HLS and Verilator
Okay, made it. Problem is, that my account is flagged as soon as I created it, I am marked as "spammy", and my "comments will only be shown in staff mode". https://github.com/verilator/verilator/issues/3159
- Attention to everyone that is using Verilator and C++! DO NOT update your GCC Package to version 11.1, because it will cause Verilator's object files to fail to compile properly. I have been dealing with this issue for four days straight and have only now found the solution. You have been warned.

Systemverilog / verilog functional editor not like vivado
If you will help me with systemverilog black box discusion (I have very low systemverilog experience) and verilator will get update then I will upload on github plugin to Sublime Text which lint whole file every time when you stop typing. Currently I have plugin based on Vivado's compiler, but compilation of simple verilog file takes 1'400ms...

eProcessor is a project that will create a open source RISC-V core for High Performance Computing (HPC)
You have verilator which is a open source simulator , so it is feasible that a "user" could fix a bug or implement a feature (i does not have to be some individual, a business or a university could do it to).

How to simulate Verilog designs REALLY quickly ?
I made a package called signalflip-js which would be good fit especially for a web app. It wraps the verilator testbench with javascript. An interesting thing to try here would be to compile verilator to wasm and use the wasm binary. DM me if you pick this route and need help

Verilator: Suggestions for verification framework?
I use signalflip-js, a framework I created using node-js before cocotb had verilator support. The framework has fairly efficient multi-clock support where it will only evaluate the model if there is an edge toggle. It also has phase support, kind of like UVM, where you can schedule tasks for Pre-run Phase, Reset Phase, Run Phase, and Post-run phase.
