   A team is developing software for an autonomous emergency braking (AEB) system. They need to validate the software's decision logic across a wide range of pedestrian scenarios. The software is compiled and runs on a host PC. They also need to verify the software's timing behavior on the target microcontroller. Which combination of XiL environments should they use?

   • AUse HiL for both decision logic and timing verification
   • BUse SiL for the decision logic and HiL for timing verification
   • CUse MiL for the decision logic and SiL for timing verification
   • DUse SiL for both decision logic and timing verification

   In a MiL test for a cruise control system, the simulated vehicle speed does not reach the set speed and oscillates. The control model is suspected to be the cause. What should the test engineer do first?

   • ACheck the control model's parameters, such as gains and time constants, for stability issues
   • BIncrease the simulation step size to speed up the test
   • CIgnore the oscillation and proceed with other tests
   • DReplace the plant model with a simpler one

   A test engineer is setting up a HiL test bench for an airbag control unit. They need to simulate crash pulses and verify the deployment timing. Which component is essential for this setup?

   • AA host PC running the software in a non-real-time environment
   • BA real-time simulator that generates crash pulse signals and measures deployment timing
   • CA data logger that records the CAN bus traffic
   • DA physical crash test vehicle
