I have several HW implementaion blocks that I develop.
I want to share them but I don't want the other ppl to see its content.
Just to use it as black box.

u can convert to blackbox by adding
`protect at the beginig and `endprotect at the end to ur source code.then compile in verilogXL with
verilog filename.v +protect.then it wl generate encrypted file with .vp extension

ex:

`protect
module xyz();
......
......
.....
endmodule
`endprotect
