Dear AAbd,
thank you for your reply.
I agree on the fact that Intel® Quartus® Prime Standard Edition software does not support IEEE 1735 encryption, indeed the command line console of Intel® Quartus® Prime Standard Edition software does not support the command encrypt_1735, which is instead supported by the Intel® Quartus® Prime Pro Edition, as specified in its user guide that you posted in your reply: I tryed to execute such command by means on the Intel® Quartus® Prime Standard Edition software command line console and it responds with an error message of the kine "command unknown". Anyway, to the best of my knowledge, this should only means that the Intel® Quartus® Prime Standard Edition software is not able to generate encrypted HDL sources, but not that is not able to parse/read/process encrypted HDL files generated with a third-party tool (that is precisely my goal).
Which is your opinion about this? Am I right? Or am I wrong?
