Used by lowRISC.
Generates C / C++ / SystemC code that does the simulation, which can then be run multiple times fast.
Claims to be very fast, but hard to use at first.
Exposes the Verilog simulation as a C++ API, which allows us to write test benches in C / C++, which is way easier than embedding it into HDL languages.
Wiki mentions it was created by DEC for Alpha, then then open sourced.
Must point to where it was installed, the executable is at VERLIATOR_ROOT/bin/verilator.
Does not need to be set for packaged Verilator installs.
When installed from source, typically equals:
export VERILATOR_ROOT='/usr/local'
Generated with a C++ API, like everything else. Awesome.
TODO: what to use for what?
