14 years agoI've used Altera's AMPcrypt tool for that. you only have to encrypt your top level entity, and then create the .qxp file.
you'll need to contact Altera directly to get that tool. By the way I think I've heard that the new Verilog \ VHDL versions include a built in encryption attribute, but I haven't tried it myself, and I don't know how much Quartus support there is.
