Altera FPGA Security solution? How to choose main chip?

Hello,

1. Yes, as far as I know

2. This is up to you - the way I see it, the security options provided on the chip utilize different methods of protecting the IP. I am not an expert in security so I can't comment on which is better.

Anyway, if you need a reference design using secure memory, refer to the two links below:

This uses Cyclone III which shouldn't be hard to port over to Cyclone IV E.
