Hello,

Outstanding technical questions that i have emailed you about:

- Are the design security features available for v12.1 Quartus?
- Do we have to enable backward compatibility (We have purchased the latest version) (How do we know which features will not work for later than v12.1 versions?)
- We need to understand if the encryption tool will be enabled and if not, what do we need to do to ensure that it gets enable?

Your reply is very much appreciated.

Thank you

Best Regards
