Choose Your Simulator
Verilator Mode (Only for logged In Users)
- Advanced linting support
- High-performance simulation
- Best for debugging and optimization
Icarus Verilog Mode
- Simple and reliable simulation
- Great for beginners
- Supports standard Verilog workflows
Please note that Verilator is NOT enough to run full UVM testbenches. It Focuses on synthesizable RTL and has limited SystemVerilog support. But It is very good for synthesizable RTL.
