Q2. Difference between task and function ?
Ans. 
Tasks are concurrent blocks of code that can run in parallel, while functions are sequential blocks of code that perform a specific task.
• Tasks can run concurrently, while functions run sequentially

• Tasks can be executed in parallel, while functions are executed one after the other

• Tasks are used for parallel processing, while functions are used for sequential processing

Q3. Difference between blocking and non-blocking
Ans. 
Blocking operations wait until the operation completes, while non-blocking operations do not wait and allow other operations to continue.
• Blocking operations halt the execution until the operation is completed

• Non-blocking operations do not halt the execution and allow other operations to continue

• Blocking operations are synchronous, while non-blocking operations are asynchronous

• Example: In a blocking operation, a functio...read more

Q1. Discuss scoreboard and how to get expected data.
Ans. 
Scoreboard is a verification component that tracks and compares expected and actual data.
• Scoreboard is used to monitor the progress of a design under test (DUT) and compare it with the expected behavior.

• It can be implemented using a register or a memory block.

• Scoreboard can be used to check the correctness of the DUT's output against the expected output.

• Expected data can be obtained from a reference model or a golden m...read more

Q2. How will you use UVM and integrate it with c based test case
Ans. 
UVM can be used to create a testbench environment and integrate it with c based test cases using DPI-C.
• Create a UVM testbench environment using SystemVerilog

• Use DPI-C to integrate the c based test cases with the UVM environment

• Define a DPI import function in SystemVerilog to call the c functions

• Use UVM sequences to drive the test cases

• Use UVM scoreboard to verify the results

• Use UVM coverage to ensure complete coverage
