verilator_profcfunc
===================

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 the time,
etc., in each Verilog block.

Due to rounding errors in gprof reports, the input report's percentages may
not total 100%.  In the verilator_profcfunc report this will get
reported as a rounding error.

For an overview of the use of verilator_profcfunc, see :ref:`Profiling`.
