Use VHDL to synthesize the MIPS single clock cycle design in the file TOP_SPIM.VHD. After synthesis and simulation perform the following steps:

Display and print the timing diagram from the simulation. Verify that the information on the timing diagram shows that the hardware is functioning correctly. Examine the test program in IFETCH.VHD. Look at the program counter, the instruction bus, the register file and ALU outputs, and control signals on the timing diagram and carefully follow the execution of each instruction in the test program. Label the important values for each instruction on the timing diagram and attach a short write-up explaining in detail what the timing diagram shows relative to each instruction's execution and correct operation.
Return to the simulator and run the simulation again. Examine the ALU output in the timing diagram window. Zoom in on the ALU output during execution of the add instruction and see what happens when it changes values. Explain exactly what is happening at this point. Hint: Real hardware has timing delays.
