Crack the Interview: Easy InSemi Round 1 Quiz Quiz

1. Understanding Coverage in Verification

   Which type of coverage measures how much of the code has been executed by tests in a verification environment?

   1. Functional coverage
   2. Code coverage
   3. Toggle coverage
   4. Data coverage
   5. Module coverage

2. Phases in UVM

   In the Universal Verification Methodology (UVM), which phase is responsible for constructing all child components from their parent component in a top-down approach?

   1. Build phase
   2. Run phase
   3. Extract phase
   4. Check phase
   5. Connect phase

3. AXI Protocol Channels

   Why does a write transaction in the AXI protocol require three channels while a read transaction uses only two?

   1. Write needs extra control data
   2. Read has no address channel
   3. Write response channel is needed to confirm write success or failure
   4. Read data arrives in two parts
   5. Read transactions require a response delay

4. Response Types in AXI

   What does an 'OKAY' response in the AXI protocol indicate about a data transfer?

   1. The transfer is delayed
   2. The transfer failed
   3. The transfer was successful
   4. Partial data was sent
   5. Data width mismatch occurred

5. UVM Handshaking Methods

   Which pair of methods are typically used in UVM sequences to begin and complete a data transaction with a driver?

   1. start_test and end_test
   2. build_item and run_item
   3. start_item and finish_item
   4. get_item and put_item
   5. start_phase and end_phase

6. Method Blocking Behavior

   In UVM, is the get_next_item() method that the driver uses to fetch sequence items from the sequencer blocking or non-blocking?

   1. Blocking
   2. Non-blocking
   3. Asynchronous
   4. Parallel phase
   5. Static

7. Location to Start UVM Sequence

   In which phase of a UVM test class is a sequence typically started to begin the verification process?

   1. build_phase
   2. end_of_elaboration_phase
   3. run_phase
   4. check_phase
   5. extract_phase

8. UVM Communication Flow

   Why is a sequencer used as an intermediate component between the driver and the sequence in UVM?

   1. To directly transfer signals to hardware
   2. To sort sequence items alphabetically
   3. To control data flow and synchronize stimulus generation
   4. To increase testbench latency
   5. To generate testbench reports

9. Purpose of uvm_config_db

   What is the main purpose of the uvm_config_db in a UVM-based verification testbench?

   1. To store simulation waveforms
   2. To store and retrieve configuration information among components
   3. To generate random numbers
   4. To synthesize test designs
   5. To check test coverage

10. Role of Virtual Interface

    What is a virtual interface in SystemVerilog and UVM?

    1. A physical wire on a chip
    2. A variable pointing to an actual interface
    3. A hardware design diagram
    4. A database of testbenches
    5. A function to start sequences
