1Reliability
If current simulation technologies are used, then simulations can be created efficiently, but they cannot adequately simulate faulty systems
Solution Approach 1:
The simulation technology dynamically switches between standard operational mode and fault operational mode based on selected fault scenarios. Each block in the model can transition between different operational states, allowing the system to adapt its behavior dynamically during simulation to reflect realistic fault conditions while maintaining the same underlying model structure.
2Reliability
If multiple fault scenarios are simulated, then realism is improved, but the complexity of creating and managing simulations increases
Solution Approach 1:
A single model can serve multiple functions by supporting both standard operational mode and various fault operational modes. The same block diagram model is reused across different fault scenarios, with the fault capability embedded in the blocks themselves rather than requiring separate models for each fault condition. This universal approach reduces the number of models needed while maintaining simulation realism.
Solution Approach 2:
Fault scenarios are pre-defined and associated with specific blocks before simulation execution. The fault-capable blocks are configured in advance with their fault modes and corresponding scenarios, allowing users to select from predefined fault conditions during simulation without needing to create or configure fault details at runtime. This preliminary configuration simplifies the simulation management process.

AI summary
A computing device may be used to create a model that includes a block. The block may represent a function corresponding to a simulation and capable of operating in a fault operational mode. The computing device may also, or alternatively, associate a fault scenario, corresponding to the model, with the fault operational mode of the block. Additionally, or alternatively, the computing device may simulate the fault scenario based on the block diagram model.
