RE: [sv-ec] question about randomization

Ray,

in the case of the scope randomize function, do variables declared within a
class and which do not have the rand or randc qualifier get randomized?

class class1
rand int data;
int base;
rand int address;

end class;
class1 obj1 = new;

initial
begin
   std::randomize(obj1);
end

Does base also get assigned random values?
An additional question is regarding the constraint which exist in the class
and the
constraint which may be provided in the std::randomize call.
Do the random values need to satisfy ALL the constraints?
