Do we get errors in SIL testing which is not found in MIL? If yes please tell me what kind of errors we get?

Hi Surekha,
In my understanding you want to know about the errors that can occur in Software-in-the-Loop (SIL) testing that are not typically found in Model-in-the-Loop (MIL) testing due to the differences in testing environments and the level of detail. Here's a brief overview:
MIL vs. SIL Testing:
MIL Testing: Focuses on validating algorithms and logic using high-level models. Errors related to algorithm logic and basic integration issues are common.
SIL Testing: Involves testing the actual software code in a simulated environment, potentially revealing issues not apparent in MIL testing.
Errors Unique to SIL Testing:
1. Integration Issues: Problems arising from the combination of software modules.
2. Resource Constraints: Memory leaks, buffer overflows, and excessive CPU usage.
3. Timing and Real-Time Behavior: Issues with task scheduling and meeting real-time constraints.
4. External System Interaction: Errors in handling simulated sensor inputs or actuator commands.
5.Data Precision and Representation: Issues due to differences in data handling between abstract models and actual software.
6. Software-Specific Errors: Syntax errors, compiler issues, and other software-related problems.
Refer to the following link for more details on MIL Testing and SIL testing:
Hope this resolves your query!
Thanks.
