Regards

input will be a for FLOP_A , output will be b for FLOP_A, input for FLOP_B will be b , and output of FLOP_B will be d.

C will optimized as at the end of simulation cycle , c and d will be having same value ..

Why will c and d have same value at the end of simulation?

haha .. Nice question. My surname is not achates ..its " Jain "

see below about the achates -- failthful friends
https://en.wikipedia.org/wiki/Achates

one more reason is , it is very rare and if you want to make user name any site , this name will be unique.

back to topic,

c and d will optimized because of blocking statement.

whatever value c having , D will also have same value , synthesis tool may put some buffer or just a wire connection ..
