FIG. 3 is an exemplary view illustrating an execution process of an RTE code generating apparatus according to the present invention. The embodiment disclosed in FIG. 3 relates to an embodiment in which the RTE code generating apparatus may extract scheduling information by analyzing a plurality of template files.
The RTE code generating apparatus 100 receives the plurality of template files. For example, the RTE code generating apparatus 100 receives a software component template file 310 for Application 1, a software component template file 320 for Application 2, an RTE template file 330, and an OS template file 340.
The RTE code generating apparatus 100 extracts the type of an application by analyzing a software component template file for an application.
For example, the RTE code generating apparatus 100 extracts information that the type of Application 1 is a periodic operational application and is operated for every 10 ms by analyzing the software component template file 310 for Application 1.

FIG. 4 is an exemplary view illustrating an execution process of an RTE code generating apparatus according to the present invention. The embodiment disclosed in FIG. 4 relates to an embodiment in which the RTE code generating apparatus may extract communication scheme information by analyzing files of a plurality of templates.
Referring to FIG. 4, the RTE code generating apparatus 100 receives files of the plurality of templates. For example, the RTE code generating apparatus 100 receives a software component template file 310 for Application 1, a software component template file 320 for Application 2, an RTE template file 330, and an OS template file 340.
The RTE code generating apparatus 100 extracts network information used to transmit data while an application is operated when the type of the application is a periodic operational application by analyzing a software component template file for the application.

FIG. 5 is a reference view for explaining a process of verifying a simulation for RTE code generation information according to the present invention.
Referring to FIG. 5, according to the related art, when RTE code generation information is that Application 1 is operated for every 10 ms and the type of an OS task used during an operation thereof is Basic, Application 1 is operated at 10 ms, 20 ms, 30 ms, and 40 ms as indicated reference numeral 510.
However, the application analyzing unit may receive RTE code generation information from the RTE code generating apparatus 100 (see FIG. 1), may analyze timing for the RTE code generation information with reference to a database on operation times for RTE generation codes, and may manage a timing error based on the analysis result.
For example, the application analyzing unit analyzes that an operation time of an OS Alarm code of the RTE code generation information is 10 ns, an operation time of an OS Task Activate code is 50 ns, and an operation time of an RTE start code is 25 ns, with reference to the database on operation times for RTE generation codes. The application analyzing unit may identify whether an integrity of an operation is not present (in particular, in an aspect of timing).
The present invention guarantees operation timing as indicated by reference 520 because the RTE code generating apparatus 100 generates RTE code generation information for an application based on an analysis result on an operation time of the application.
FIG. 6 is a reference view for explaining a process of verifying a simulation for RTE code generation information according to the present invention.
Referring to FIG. 6, the RTE code generating apparatus 100 (see FIG. 1) may extract information that an Rte_Write_Application1( ) function in a communication form using a software buffer should be provided because an application is operated by a specific request and data are transmitted to another application in the application, by analyzing a software component template file on the application.
The application analyzing unit analyzes an operation time of an Rte_Write_Application1( ) function of the RTE code generation information generated by the RTE code generating apparatus 100 with reference to a database on operation times for RTE generation codes. For example, the RTE code generating apparatus 100 may analyze an operation time of an Rte_internal function 1 as being 10 ns and may analyze an operation time of an Rte_internal function 2 as being 25 ns with reference to the database for operation times for RTE generation codes.
The RTE code generating apparatus 100 may extract network information used to transmit data while an application is operated for a specific period by analyzing a software component template file for the application. Furthermore, the application analyzing unit may analyze a timing of the RTE code generation information generated by the RTE code generating apparatus 100 with reference to a database on operation times for RTE generation codes.
For example, the application analyzing unit may analyze that an operation time of an AUTOSAR COM( ) function used to transmit data when an Rte_Write_Application2( ) function of the RTE code generation information is executed, an operation time of an AUTOSAR PduR( ) function is 30 ns, an operation time of an AUTOSAR_Canlf( ) is 15 ns, and an operation of an AUTOSAR CanDriver function is 20 ns, with reference to the database for operation times for RTE generation codes.
FIG. 7 is a reference view for explaining a process of verifying a simulation for RTE code generation information according to the present invention.
Referring to FIG. 7, the type of an application mapped in OsTask_A is a periodic operational application and the application is operated at every 10 ms. The type of an application mapped in OsTaskB_is a non-periodic operational application, and the application is executed according to an operation request by OsTask_A. The type of an application mapped in OsTask_C is a periodic operational application and the application is operate at every 20 ms.
For example, if an operation of the application mapped in OsTask_C is ended, the application mapped in OsTask_A is operated. OsTask_A is operated again at the next period. The application 710a mapped in OsTask_A requests an execution of an application 720 mapped in OsTask_B in an execution process, and if the execution of the application 720 mapped in OsTaskB_is ended, the remaining application 710b of the application 710a mapped in OsTask_A, which is not executed, is executed.
However, due to a call of OsTask_A, OsTask_B is performed such that OsTask_C is not executed in a period of its own but is postponed to a time point when the second period of OsTask_A ends.
In this way, the present invention can develop application software in which operation timing and an operation stability are secured, by generating RTE code generation information on an application in consideration of an actual operation time of the application.
