Physics questions

1.     Let me ask you a VHDL concept question.
See the code below.
xyz<= NOT xyz;
Will this be synthesized into a flip flop? What type of FF?

1.     Let's talk about on state diagram.

If I have to add a return arrow from 011 to 010 based on an input's status (say IN1, 0 goes left, 1 goes to right), can you write the VHDL code for the above diagram? This image is captured from your lecture note.
