   A project team is considering using MiL testing for a new electric power steering (EPS) system. They need to test the model's behavior under various road conditions and driver inputs. They have a limited budget and need to deliver the software quickly. Which of the following is a key benefit of MiL testing in this context?

   • AMiL testing can be performed before any hardware is available, allowing early validation and reducing development time
   • BMiL testing provides the highest fidelity of the real system
   • CMiL testing is always faster than real-time, so it can test more scenarios in less time
   • DMiL testing eliminates the need for any further testing

   During a MiL test of an anti-lock braking system (ABS) model, the test engineer observes that the model's output does not match the expected behavior for a high-friction surface. The test harness is correctly configured. What is the most likely first step to diagnose the issue?

   • AReplace the test harness with a different one
   • BSwitch to a HiL test to verify the model
   • CReview the model's internal states and signals during the simulation
   • DIgnore the mismatch and proceed to the next test case
