VHDL Code: Design a 16-bit 4-to-1 multiplexer using data-flow
implementation style. Data inputs and output should be 16-bit
vectors. In your test bench, you should include enough number of
test cases to show the correctness of your design.
Try designing a 4 bit Multiplexer using two 2-bit multiplexer
design given below and verify the design by simulating it.
module Mux2x1(In0,In1,sel,out);
input In0,In1,sel;
output out;
assign out = (sel)?In1:In0;
endmodule
Pls include the verilog design module,testbench, waveform

and file-writing operations?
a. Java
b. Fragment-based methods
c. onClick
d. DDMS
2. What would this query return? SELECT * FROM Items WHERE
OrderDate >= Date('Now')
a. All items in the database.
b. Nothing
c. Items that were ordered yesterday
d. Items that were ordered today.
3. What can you use to manage files within a desired directory
and create subdirectories?
a. Subdirectory objects
b. Directory class
c. File objects

Create a 4-bit full adder design using VHDL in vivado
2017.2.
Project description: You need to create a vhd file for the
four-bit full adder.
Note: Instead of using bit, please use std_logic; instead of
using bit_vector, please use std_logic_vector.
One simulation source is required, i.e. testbench
Please don't write out on paper. Code written out in text or
screen shots would be very much apprecitated.
Design and Test an 8-bit Adder using 4-bit adder. Use
4-bit adder coded in class using full adder that is coded
using data flow model. Use test bench
to test 8-bit adder and consider at least five different test
vectors to test it.
1. A) Select the themes of design using
Return on Investment ROI (Rate of Return)
method, the data of both equipment are shown the
table below,
B) Compare the effect of decrease in initial
cost of 5% on the rate of return for equipment A (calculate the %
of change in ROI).
