For the process given below, A, B, C, and D are all integers that have a value of 0 at time = 10 ns. If E changes from '0' to '1' at time 20 ns, specify all resulting changes. Indicate the time at which each change will occur, the signal/variable affected and the value to which it will change.   process     variable F: integer:=1; variable A: integer:=0; begin      wait on E;      A := 1;      F := A + 5;      B <= F + 1 after 5 ns;      C <= B + 2 after 10 ns;      D <= C + 5 after 15 ns;      A := A + 5; end process;

Question

For the process given below, A, B, C, and are all integers that have a value of 0 at time = 10 ns. If E changes from '0' to '1' at time 20 ns, specify all resulting changes. Indicate the time at which each change will occur, the signal/variable affected and the value to which it will change.

 

process

    variable F: integer:=1; variable A: integer:=0;

begin

     wait on E;

     A := 1;

     F := A + 5;

     B <= F + 1 after 5 ns;

     C <= B + 2 after 10 ns;

     D <= C + 5 after 15 ns;

     A := A + 5;

end process;
