Abstract

The present disclosure generally relates to improvements in validating control specifications and more particularly pertains to a system and method to hierarchically validate graphically based executable logic control specifications. This method may include identifying, by a processor for hierarchically validating a graphically based logic control specification, a functional hierarchy of a first application of the control specification comprising a first feature. The method may include executing, by the processor, a specific first feature test case on the first feature to at least one of validate a structure of the first feature and validate that a specific functional requirement of the first feature is met.

Claims

1. A computer-based method comprising the steps of:

identifying, by a processor for hierarchically validating a graphically based logic control specification, a functional hierarchy of a first application of the control specification comprising a first feature that comprises a first module, the first module being at a lower layer or level than the first feature, and the first feature being at a lower layer or level than the first application;

executing, by the processor, a first module test case on the first module to at least one of validate a structure of the first module or validate that a functional requirement of the first module is met;

executing, by the processor, a first feature test case on the first feature after executing the first module test case to at least one of validate a structure of the first feature or validate that a functional requirement of the first feature is met; and

executing, by the processor, a first application test case to the first application after executing the first feature test case to validate a functional requirement of the first application is met.

2. The computer-based method of claim 1, further comprising the steps of:

executing, by the processor, a second feature test case to a second feature to at least one of validate a structure of the second feature or validate that a functional requirement of the second feature is met, wherein the functional hierarchy comprises the second feature, and wherein the validation of the second feature includes the validation of first feature results.

3. The computer-based method of claim 1, wherein the first feature comprises a plurality of modules, and the method further comprises executing, by the processor, a plurality of module test cases on the plurality of modules to at least one of validate a structure of each of the plurality of modules or validate that a functional requirement of each of the plurality of modules is met.

4. The computer-based method of claim 1, further comprising translating text based code into graphically based logic.

5. The computer-based method of claim 1, further comprising translating graphically based logic into text based code.

6. The computer-based method of claim 1, further comprising validating all of a plurality of applications in the control specification.

7. The computer-based method of claim 1, further comprising identifying, by the processor, a functional hierarchy of the first feature of the first application.

8. The computer-based method of claim 1, further comprising starting at the end of the control specification and validating to the beginning.

9. The computer-based method of claim 1, further comprising validating an entire electronic control unit.

10. The computer-based method of claim 9, wherein the electronic control unit is an electronic control unit of a vehicle.

11. The computer-based method of claim 1, wherein a unique feature test case is developed to validate each feature'"'"'s unique functional requirement.

12. The computer-based method of claim 1, wherein the hierarchical validation process flows from module level to feature level to application level.

13. The computer-based method of claim 1, further comprising subdividing the feature functional hierarchy based on computational constraints.

14. The computer-based method of claim 1, wherein overlapping test case validation provide substantially exhaustive validation coverage.

15. The computer-based method of claim 1, wherein each feature comprises a function within the graphically based logic control specification.

16. The computer-based method of claim 1, wherein the computer-based method is used to validate the control specification to an International Organization for Standardization (ISO) specification.

17. The computer-based method of claim 1, wherein elements of the graphically based logic control specification are rendered on a user interface.

18. The computer-based method of claim 1, further comprising executing, by the processor, a second application test case on a second application to validate that a functional requirement of the second application is met.

19. A system comprising:

a processor configured to hierarchically validate a graphically based logic control specification,

a tangible, non-transitory memory configured to communicate with the processor,

the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations comprising;

identifying, by a processor for hierarchically validating a graphically based logic control specification, a functional hierarchy of a first application of the control specification comprising a first feature that comprises a first module, the first module being at a lower layer or level than the first feature, and the first feature being at a lower layer or level than the first application;

executing, by the processor, a first module test case on the first module to at least one of validate a structure of the first module or validate that a functional requirement of the first module is met;

executing, by the processor, a first feature test case on the first feature after executing the first module test case to at least one of validate a structure of the first feature or validate that a functional requirement of the first feature is met; and

executing, by the processor, a first application test case to the first application after executing the first feature test case to validate a functional requirement of the first application is met.

20. An article of manufacture including a non-transitory, tangible computer readable storage medium having instructions stored thereon that, in response to execution by a computer-based system configured to hierarchically validate a graphically based logic control specification, cause the computer-based system to perform operations comprising:

identifying, by the computer-based system, a functional hierarchy of a first application of the control specification comprising a first feature that comprises a first module, the first module being at a lower layer or level than the first feature, and the first feature being at a lower layer or level than the first application;

executing, by the processor, a first module test case on the first module to at least one of validate a structure of the first module or validate that a functional requirement of the first module is met;

executing, by the computer-based system, a first feature test case on the first feature after executing the first module test case to at least one of validate a structure of the first feature or validate that a functional requirement of the first feature is met; and

executing, by the computer-based system, a first application test case to the first application after executing the first feature test case to validate a functional requirement of the first application is met.
