Q2. What is m_sequencer and p_sequencer?
Ans. 
m_sequencer and p_sequencer are components used in design and verification for sequencing operations.
• m_sequencer and p_sequencer are commonly used in digital design for controlling the sequence of operations.

• m_sequencer typically refers to a master sequencer, while p_sequencer refers to a peripheral sequencer.

• These components are often used in verification environments to ensure proper sequencing of events.

Q3. What is factory override in UVM?
Ans. 
Factory override in UVM allows users to replace default factory methods with custom implementations.
• Factory override is used to customize the behavior of UVM components without modifying the original source code.

• It allows users to replace default factory methods with custom implementations to meet specific requirements.

• Factory override can be useful for debugging, testing, or adding new features to existing UVM compone...read more

Q4. What is the call back in UVM?
Ans. 
A call back in UVM is a mechanism used to notify a component about a specific event or condition.
• A call back is defined using a function or task in the UVM component.

• It is registered with the UVM framework to be executed when a certain event occurs.

• Call backs are commonly used for handling events like transaction completion or error detection.

Q2. What are blocking and non blocking assignments?
Ans. 
Blocking assignments wait for the assigned value to be calculated before moving on to the next statement, while non-blocking assignments allow multiple assignments to occur simultaneously.
• Blocking assignments use the = operator, while non-blocking assignments use the <= operator

• Blocking assignments are executed sequentially in the order they appear in the code, while non-blocking assignments are executed concurrently
