How are you simulating the designs for the FPGA? Are you paying for ModelSim?

No, I'm not paying for ModelSim. I've been using free tools like Icarus Verilog — it was good enough for my needs so far. If I need more performance later, I might migrate to Verilator. I could also use Vivado’s built-in XSim, but coming from a software background, I generally prefer more Unix-style tools rather than heavier hardware IDEs.
