VHDL CODE

In this assignment, you will design and synthesize the following designs using Xilinx Vivado:

1. 32:1 multiplexer using four 8:1 and one 4:1 multiplexer
2. 5-to-32 decoder
3. A 4-bit wide computational unit according to the following function table:

Selector	Operation	Function
“00”	Output <= Input	No shift
“01”	Output <= Shift-left (Input)	Shift Left
“10”	Output <= Shift-right (Input)	Shift Right
“11”	Output <= 0	Zero output

 

 

For each question above, submit vhdl code, RTL schematic, synthesis report, screenshots of simulation waveforms, and test bench of the designs. Test your design using at least five test cases. Mark two of the test cases and show the corresponding inputs, expected outputs and simulated outputs for those two cases. The source files should contain appropriate comments for better understanding.
