Add your answer
Q2. Umv basic principle
Ans. 
UVM (Universal Verification Methodology) basic principle is to provide a standardized methodology for verifying digital designs.
• UVM is based on SystemVerilog and provides a framework for creating reusable verification environments

• It promotes the use of object-oriented programming techniques for creating modular and scalable testbenches

• UVM encourages the use of constrained-random stimulus generation and coverage-driven ...read more

Q2. Coverage to write transitions of states.
Ans. 
Coverage-driven verification techniques are used to ensure all possible state transitions are exercised.
• Coverage metrics like state, transition, and toggle coverage can be used to track the completeness of state transitions.

• Writing directed tests to cover specific state transitions can help achieve higher coverage.

• Random stimulus generation can also be used to explore different state transitions.

• Functional coverage can...read more

Q2. Use uart protocol to solve a problem?
Ans. 
UART protocol can be used to transmit and receive data between two devices.
• UART can be used to communicate between a microcontroller and a computer

• UART can be used to send and receive data between two microcontrollers

• UART can be used to interface with sensors and actuators

• UART can be used to implement a simple command/response protocol

• UART can be used to implement a data logging system

Q3. Use uart to receive signals from micrcontroller
Ans. 
UART can be used to receive signals from a microcontroller.
• Connect the UART pins of the microcontroller to the UART pins of the receiving device.

• Configure the UART settings such as baud rate, parity, and stop bits.

• Use a UART library or write code to read the incoming data from the UART buffer.

• Process the received data as required by the application.
