Greetings, I'm trying to implement the design below.

I'm working on a research project in which I would implement the shown design, which is a variation of a cyber-physical security device called the Physically Unclonable Function (PUF), and later perform a security analysis on it.

Throughout the literature, the design has been implemented on FPGAs, and given that my university already possesses a Cyclone II DE2, they lent one to me to implement the shown design.

My issue is that it requires both knowledge of manual place & routing and the design of its fundamental gate, which is a tristate inverter, but I'm unable to do either because I'm quite novice in the world of FPGAs and that I'm not able to read the figures the image I provided.

Your help is highly appreciated,

Thank you in advance,

Regards.
