Verilator_profcfunc reads a profile report created by gprof. The names of the functions are then transformed, assuming the user used Verilator’s –prof-cfuncs, and a report printed showing the percentage of time, etc, in each Verilog block.

For an overview of use of verilator_profcfuncs, see Code Profiling.
