Fill in the VHDL to implement the illustrated circuit. Assume that clk and rst connect to every register in the schematic. All wires/operations are width bits except for in4, which is a single bit. Ignore adder overflow. Assume the mux selects the left input when in4 = ‘1’. Use the next page if necessary.   — Write code in specified regions creating the diagram used above –library ieee;use ieee.std_logic_1164.all;use ieee.numeric_std.all;entity diagram is       generic (width : positive := 8);       port(              clk, rst : in std_logic;              in1, in2, in3 : in std_logic_vector(width-1 downto 0);              in4 : in std_logic;              out1, out2 : out std_logic_vector(width-1 downto 0));end diagram;architecture BHV of example is  –Region 1: Write code below initializing any signals here–begin process(clk, rst)      begin — Region 2: Write code —           elsif (rising_edge(clk)) then  — Region 3: Write Code —                      end if;  end process;– Region 4: Write Code –end BHV;

A single assignment to all outputs at the beginning of a process for combinational logic will guarantee there are no latches for that logic

Fill in the following code for the behavioral architecture of an ALU using the numeric standard library.

Suppose you approximating the solution of a simple differential equation involving the function , and you appeal to the relation

TRUE or FALSE? A  fixed-increment simulation clock is well-suited for simulations that model continuous-time systems such as the movement of an approaching weather system.

There are 5 random people in a room.  What is the probability that at least two of them share the same birthday?  (Assume 365 days are equally likely.)

Suppose that and are i.i.d. random variables. How would you simulate a discrete uniform random integer between 1 and 12 (e.g., a 12-sided die toss)?
