I have been using the IEEE 1735 encryption tool in Quartus Pro 17.1 but I cannot seem to find the right way of using the --simulator option. I issue the following command:

C:>C:/intelFPGA_pro/17.1/quartus/bin64/encrypt_1735.exe --language=vhdl --simulation=mentor test.vhd
An invalid option was supplied to the --simulation argument.

I have tried to format it in all sorts of ways e.g. caps, brackets, ==, etc. but cannot find any way in which the tool seems to think that the argument is valid. If someone knows what how to get this to work then please do also let me know how to give multiple arguments to this simulator argument. I would like to be able to limit the encryption to 2 specific simulators.

I also just wanted to make sure but as far as I understand, as long as I don't add --quartus to the arguments then the code will not be synthesizable.
