Can someone please help me solving this. Setup and hold equations for this flip flop combination.
By my understanding, I am able to get the setup equation, but I am confused on why do we even have a hold violation in this ckt. If setup is met, hold is already met (as per my understanding]. Please correct me if I am wrong and help me with a complete correct answer. Thanks!

Firstly, the setup time equation for capturing flop (here FF2) should be -
(Here I have assumed that there is no clock skew between the flops and instead of that there is T_inv delay and T_comb is same as T_pd)
T_c2q + T_comb + T_setup <= T_clk + T_inv
Now, to avoid hold time violation for launching flop, the data should be stable for some time at T_hold after the clock edge -
T_c2q + T_comb >= T_hold + T_inv

Also for knowing there are no timing violations, there should be values given for the variables to definitely know there aren't hold time violations.

Let me know if you have some corrections
