I am trying to write the code for an 8 bit adder in VHDL so that
I can program it onto my Elbert V2 Spartan 3A FPGA Development
Board, but I keep getting errors. Any ideas what I am doing
wrong?
library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
entity adder8bit is
Port ( a : in STD_LOGIC_VECTOR(7 downto 0);
b : in STD_LOGIC_VECTOR(7 downto 0);
cin : in STD_LOGIC;
o : out STD_LOGIC_VECTOR(7 downto 0);
cout : out STD_LOGIC);
end adder8bit;

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.
Write VHDL code (behavior model) to implement a 4-bit modulo-9
counter and simulate your VHDL code of 4-bit modulo-9 counter in
ModelSim, and capture the screenshot
of your simulated waveform.
Assume clock period Tclk=100ns, initially, the counter is reset
to Q3Q2Q1Q0=0000 you
need to simulate a complete counting cycle plus one more additional
clock period after it is reset to “0000” state.
Write a VHDL code for a 4-bit comparator which takes two 4-bit
input values and (0.5) determines whether the numbers are equal. 2.
2. Write a structural VHDL code to implement the circuit of Fig. 2,
