Policy classes are used to implement polymorphic operations that differ between built-in types and class-based types. Generic components can then be built that work with either classes or built-in types, depending on what policy class is used.
| Policy Classes | Policy classes are used to implement polymorphic operations that differ between built-in types and class-based types. |
| uvm_built_in_comp #(T) | This policy class is used to compare built-in types. |
| uvm_built_in_converter #(T) | This policy class is used to convert built-in types to strings. |
| uvm_built_in_clone #(T) | This policy class is used to clone built-in types via the = operator. |
| uvm_class_comp #(T) | This policy class is used to compare two objects of the same type. |
| uvm_class_converter #(T) | This policy class is used to convert a class object to a string. |
| uvm_class_clone #(T) | This policy class is used to clone class objects. |
This policy class is used to compare built-in types.
Provides a comp method that compares the built-in type, T, for which the == operator is defined.
| uvm_built_in_comp #(T) | ||||||||
| This policy class is used to compare built-in types. | ||||||||
| Class Declaration | ||||||||
| ||||||||
This policy class is used to convert built-in types to strings.
Provides a convert2string method that converts the built-in type, T, to a string using the %p format specifier.
| uvm_built_in_converter #(T) | ||||||||
| This policy class is used to convert built-in types to strings. | ||||||||
| Class Declaration | ||||||||
| ||||||||
This policy class is used to clone built-in types via the = operator.
Provides a clone method that returns a copy of the built-in type, T.
| uvm_built_in_clone #(T) | ||||||||
| This policy class is used to clone built-in types via the = operator. | ||||||||
| Class Declaration | ||||||||
| ||||||||
This policy class is used to compare two objects of the same type.
Provides a comp method that compares two objects of type T. The class T must provide the method “function bit compare(T rhs)”, similar to the uvm_object::compare method.
| uvm_class_comp #(T) | ||||||||
| This policy class is used to compare two objects of the same type. | ||||||||
| Class Declaration | ||||||||
| ||||||||
This policy class is used to convert a class object to a string.
Provides a convert2string method that converts an instance of type T to a string. The class T must provide the method “function string convert2string()”, similar to the uvm_object::convert2string method.
| uvm_class_converter #(T) | ||||||||
| This policy class is used to convert a class object to a string. | ||||||||
| Class Declaration | ||||||||
| ||||||||
This policy class is used to clone class objects.
Provides a clone method that returns a copy of the built-in type, T. The class T must implement the clone method, to which this class delegates the operation. If T is derived from uvm_object, then T must instead implement uvm_object::do_copy, either directly or indirectly through use of the `uvm_field macros.
| uvm_class_clone #(T) | ||||||||
| This policy class is used to clone class objects. | ||||||||
| Class Declaration | ||||||||

This policy class is used to compare built-in types.
class uvm_built_in_comp #( type T = int )
This policy class is used to convert built-in types to strings.
class uvm_built_in_converter #( type T = int )
This policy class is used to clone built-in types via the = operator.
class uvm_built_in_clone #( type T = int )
This policy class is used to compare two objects of the same type.
class uvm_class_comp #( type T = int )
This policy class is used to convert a class object to a string.
class uvm_class_converter #( type T = int )
This policy class is used to clone class objects.
class uvm_class_clone #( type T = int )
Deep compares members of this data object with those of the object provided in the rhs (right-hand side) argument, returning 1 on a match, 0 othewise.
function bit compare ( uvm_object rhs, uvm_comparer comparer = null )
This virtual function is a user-definable hook, called directly by the user, that allows users to provide object information in the form of a string.
virtual function string convert2string()
The uvm_object class is the base class for all UVM data and hierarchical classes.
virtual class uvm_object extends uvm_void
The do_copy method is the user-definable hook called by the copy method.
virtual function void do_copy ( uvm_object rhs )
