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 time, etc, in
|
|
each Verilog block.
|
|
|
|
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.
|
|
|
|
For an overview of use of verilator_profcfunc, see :ref:`Profiling`.
