In the following VHDL code, $A,B,C,$ and $D$ are integers that are $0$ at time $10ns.$ If $D$ changes to $1$ at $20ns,$ specify the times at which $A,B,$ and $C$ will change and the values they will take. $[$ marks$]$

process$($D$)$

begin

$A1$ after $5ns$

$BA+1$;$-$ executes before A changes

$CB$ after $10ns$;$--$ executes before $B$ changes

end process;
