Hello Dave,

Can you please guide me to know is it possible to write like

covergroup cg(ref bit [3:0]hello.bye); 

   coverpoint hello.bye{
    bins a ...;
    bins b ...;
    ...
    ...
}

I mean to say can we use hierarchical reference in covergroup definition where array of covergroup is implemented. Please guide.
