In reply to verif_learner:
This is known as an abstract class with pure virtual methods
virtual class base;
pure virtual function void func_x;
virtual function void func_y;
func_x;
endfunction
endclass
class base cannot be constructed directly; it must be extended with an implementation of func_x.
Dave,
I assume pure virtual method is sufficient to enforce that derived class implements such a method. I don’t think the class needs to be virtual.
I assume a non virtual class with a pure virtual method can be instantiated …
