The main question is: do we want conversion on RTL or Gate levels?
For RTL, I completely agree that "by hand" approach is the safest one.
For gatelevel, just dump your design to vhdl format after running
synthesis, or load your verilog gatelevel to the synthesis tool and
then save it in vhdl format.
