Complete the following to have the correct answer:

1. What will be the final value of x1,w1,x2 and w2 for the following different Verilog codes, if the initial values of x1,x2 and y equal 1,4,5 respectively.

1. always @ (posedge clk)

begin

x1 = y;

w1 = x1 + 2;

end

X1 =____, W1 =_____,

2. always @ (posedge clk)

begin

x2 <= y;

w2 <= x2 + 2;

end

X2=______, W2=_____
