Please explain how to do so step by step Need a lot of help! Thank you!

Consider an 8-bit shifting circuit that can perform rotating right or rotating left. An additional 1-bit control signal, lr, specifies the desired direction. Design the circuit using one rotate-right circuit, one rotate-left circuit, and one 2-to-1 multiplexer to select the desired result. Derive the code. Derive a testbench and use simulation to verify operation of the code. Synthesize the circuit, program the FPGA, and verify its operation. This circuit can also be implemented by one rotate-right shifter with pre- and post-reversing circuits. The reversing circuit either passes the original input or reverses the input bitwise (e.g., if an 8-bit input is a_7a_6a_5a_4a_3a_2a_1a_0, the reversed result becomes a_0a_1a_2a_3a_5a_5a_6a_7). Repeat steps 2 and 3. Check the report files and compare the number of logic cells and propagation delays of the two designs
