What is virtual in UVM?
Virtual method functionality is set at run‐time, which allows extended class handles to be assigned to base class handles and run‐time method calls using the base class handle will execute the extended class method functionality. This is a powerful feature that is called polymorphism.
What is UVM extern?
Using extern qualifier in method declaration indicates that the implementation is done outside the body of this class. …
What is M_sequencer and P_sequencer in UVM?
m_sequencer is the generic uvm_sequencer pointer. it will always exist for the uvm_sequence and is initialized when the sequence is started. p_sequencer is a typed-specific sequencer pointer, created by registering the sequence to the sequencer using macros.
How do you write a virtual sequence in UVM?
In UVM, Virtual Sequence can be implemented using 2 approaches.
- In the 1st approach, Virtual Sequence will contain itself the handles of the Agent’s Sequencers on which the Sub-Sequences are to be executed.
- In the 2nd approach, Virtual Sequence will run on a Virtual Sequencer which is of type uvm_sequencer.
What is the use of extern?
the extern keyword is used to extend the visibility of variables/functions. Since functions are visible throughout the program by default, the use of extern is not needed in function declarations or definitions. Its use is implicit. When extern is used with a variable, it’s only declared, not defined.
Which one of the library class is not a virtual class in UVM?
All UVM component bas classes are NOT virtual classes. A virtual class is a class which cannot be used to make directly an object.
What is $cast in UVM?
When $cast is called as a function, it will attempt to assign the source expression to the target variable and return 1 if it succeeds. It does not make the assignment if it fails and returns 0.
What is the UVM environment?
The UVM Environment is a hierarchical component that groups together other verification components that are interrelated. Typical components that are usually instantiated inside the UVM Environment are UVM Agents, UVM Scoreboards, or even other UVM Environments.
How to write the UVM_sequence_item?
The sequence-item is written by extending the uvm_sequence_item, uvm_sequence_item inherits from the uvm_object via the uvm_transaction class. therefore uvm_sequence_item is of an object type.
What are the arguments of a UVM_*Utile class?
Classes derived from uvm_component have two arguments, a name and a uvm_component parent. The two `uvm_*utile macros inserts code that gives you a factory create () method that delegates calls to the constructors of uvm_object or uvm_component.
What does UVM stand for?
UVM (Universal Verification Methodology) is a standardized methodology for verifying the both complex & simple digital design in simple way. Question 2. Uvm Derived From Which Language?
