* Originally verilator will generate a large cpp file containing a large function, which costs about 13 min to compile. By using --output-split-cfuncs, this large function will be splitted into several functions in servral files. This will greatly improve the compile time with 'make -j'. By '-j32', the compile time can be reduced to about 1 min.
