Commercially, Philips
Semiconductors (now NXP) have led the way. Their use of Verilator is becoming more widespread, for example within application notes. More recently Art of Silicon have described their use of Verilator on a farm of Linux processors as a route to faster regression testing of their

Verilator converts
Verilog to C++ or SystemC. It can handle all versions of Verilog and also some SystemVerilog assertions. The approach is closer to synthesis than event-driven simulation. The entire design is flattened (that is, all modules are expanded to create one module). Static analysis is

Verilator identified 27 companies and universities who had reported use of Verilator or contributed to its development, including Intel, Arm, CSR, Broadcom, Raytheon, Infineon, Stanford University, Imperial College London and Embecosm.

Version 5 added an IEEE-compliant scheduler and delay semantics, relaxing previous restrictions that ignored all delays.

Verilator has seen its widest adoption in the academic and open source communities. The semiconductor industry has been more cautious in its adoption of an open source tool, and has the financial means to use commercial alternatives.
