UVM factory create
UVM (Universal Verification Methodology) is a widely used methodology for verifying integrated circuit designs. The UVM factory is a key component of the UVM framework, responsible for creating and managing objects dynamically.
To create an object using the UVM factory, you need to follow these steps:
Define a base class for your object. This class should inherit from
uvm_object
or any of its derived classes, such asuvm_component
,uvm_sequence
, etc.Register your class with the UVM factory. This step ensures that the factory is aware of your class and can create objects of that type. You can register your class using the
uvm_component_utils
macro or theuvm_object_utils
macro, depending on the base class you are inheriting from.Use the
create()
method of the UVM factory to create an instance of your object. Pass the class type as an argument to thecreate()
method, and it will return a pointer to a newly created object.
Here's an example of how you can create an object using the UVM factory:
class MyObject extends uvm_object;
// ...
endclass
// Register MyObject with the UVM factory
`uvm_object_utils(MyObject)
// Create an instance of MyObject
MyObject myObj = MyObject::type_id::create("myObj");
In this example, the MyObject
class is registered with the UVM factory using the uvm_object_utils
macro. Then, the create()
method is used to create an instance of MyObject
and assign it to the myObj
variable.
