Common Mistakes to Avoid
Common procurement failures come from selecting tools that do not cover the full pipeline from determinism and code generation through traceable verification evidence and defect finding for safety-critical concerns.
Choosing a model tool without a complete verification and traceability workflow
Relying on MathWorks Simulink alone can leave teams without coverage-driven requirements-to-test tracing, which is why MathWorks Simulink Verification and Validation exists for model coverage analysis and traceability. For SCADE-based development, using Ansys SCADE Suite without Ansys SCADE Test can leave test management and coverage evidence disconnected from requirements-backed test cases.
Generating code without planning determinism settings and integration interfaces
Using MathWorks Simulink Coder without disciplined configuration of deterministic, options-driven embedded integration can make real-time scheduling issues show up late. Using MathWorks Embedded Coder without attention to configurable determinism and interface packaging increases the chance of integration friction when connecting flight logic to platform services.
Skipping static analysis for runtime errors in safety-critical C and C++
Relying only on simulation and tests can miss overflow, bounds violations, and concurrency-related flaws that MathWorks Polyspace Bug Finder targets through static detection. Polyspace’s MISRA C and CERT C rule support requires correct setup context, but it closes critical gaps that code review and unit tests often miss.
Picking HDL generation tools when the architecture does not include FPGA or ASIC compute
Including MathWorks HDL Coder when the compute path does not use synthesizable Verilog or VHDL generation can add unnecessary toolchain complexity and fixed-point workflow overhead.
