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