Description

AUTOSAR RTM-based test method and device
Technical Field
The invention relates to the technical field of automobiles, in particular to an AUTOSAR (automobile open system architecture) RTM (run-time measurement) based test method and an AUTOSAR RTM based test device.
Background
The automobile open system architecture (AUTomotive Open System Architecture, AUTOSAR) is a consortium that is dedicated to the development of automobile electronic software standards. AUTOSAR is built jointly by global automobile manufacturers, component suppliers and other electronic, semiconductor and software system companies, each member maintains a development partnership, each partnership is brought into hand-in-hand cooperation, and aims to develop an open and standardized software architecture for the automobile industry. The AUTOSAR architecture is beneficial to the exchange and update of vehicle electronic system software, and provides a foundation for efficiently managing more and more complex vehicle electronic and software systems.
In AUTOSAR, ECU software is abstracted into three layers: basic Software (BSW), runtime Environment (RTE), and application layer. The BSW contains four parts, a microcontroller abstraction layer (Micro Controller Abstraction Layer, MCAL), an electronic control unit (Electronic Control Unit, ECU) abstraction layer, a service layer, and complex drivers. The MCAL contains a driver related to hardware and can be used for directly accessing memory, communication, I/O and the like; the ECU abstract layer provides a unified access interface for an upper layer to realize access to communication, memory or I/O; the service layer provides various background services; the complex drive includes a driver associated with the sensor and the actuator.
The application layer is used for realizing specific functions of the ECU and comprises a plurality of AUTOSAR software components (SoftwareComponent, SWC). The behavior of the SWC is realized through one or more Runnable entities (Runnable), wherein Runnable is the smallest code segment in the SWC, and finally, the code segment is mapped to a specific task of an operating system, and the operating system performs scheduling to complete corresponding functions.
The RTE implements the execution of the AUTOSAR virtual function bus and the SWC and ensures consistency of data exchanges between the SWCs and between the SWC and the BSW.
To facilitate user determination of runtime information of code segments and CPU loads generated by code segments at runtime, AUTOSAR provides runtime measurement (Runtime Measurement, RTM) functionality. RTM is used to measure the runtime and CPU load of BSW module code, and also to measure the runtime and CPU load of user-defined code segments. RTM measurements currently have Count, max, min, average and Average CPU load. Wherein Count represents the occurrence frequency of the start function and the stop function, max represents the longest operation duration of the start-stop segment of the code segment, min represents the shortest operation duration of the start-stop segment of the code segment, average represents the Average operation duration of the start-stop segment of the code segment, and Average CPU load represents the Average CPU load of each start-stop segment operation. AUTOSAR RTM provides functions such as error report, current CPU load and software execution time measurement, and the like, and can greatly simplify the development and test process of ECU software.
Fig. 1 is a schematic diagram of an RTM measurement load based on an AUTOSAR in the prior art, and as shown in fig. 1, an RTM implementation manner based on an AUTOSAR architecture is as follows:
step A, configuring an AUTOSAR RTM function;
enabling an RTM function in the BSW module;
step C, adding a start function and a stop function of an RTM measurement start function for measuring SWC;
step D, obtaining the measurement result through XCP (Universal Measurement and Calibration Protocol ) protocol.
However, in implementing the present invention, the inventor has found that, in the current scheme based on runtime measurement of the AUTOSAR architecture, the scheme based on configuration tool chain has some problems, and is specifically described as follows:
when the measuring points are added, the macro functions of the start and stop generate codes for the RTM module, and the codes are not universal and are not beneficial to multiplexing of other engineering codes.
The configuration of the measurement points cannot be shut down at any time, the order is adjusted, and the presented result is not the most desired order for the user.
The measurement of the time of occurrence of abnormality can not be displayed as a result in operation, which is unfavorable for automatic test, and frequent observation is required by personnel, thus reducing development efficiency.
At present, no good method exists for supporting a Task (Task) level by measuring points, a measuring point starting code of the Task is manually added, and after the AUTOSAR tool chain regenerates the code, the code can be cleaned up, so that development and debugging are inconvenient.
In summary, the current run-time measurement based on the AUTOSAR architecture has the problems of insufficient requirement, low development efficiency and poor code reusability.

Referring to fig. 2, a flowchart illustrating steps of an embodiment of a test method based on an AUTOSAR RTM according to the present invention may specifically include the following steps:
step S210, decoupling an RTM module of an AUTOSAR tool chain into a static code library and a Wrapper RTM Wrapper;
specifically, when the RTM is required to be measured during running, the AUTOSAR RTM module is firstly subjected to generalized configuration, a code part for realizing the overall function of the RTM module is used as a static code library, and an intermediate layer of the AUTOSAR RTM module, namely an RTM Wrapper, is developed based on the AUTOSAR RTM module, and is used for realizing RTM measurement of a code segment or Task. Unlike the prior art that the measurement function is directly set in the RTM, the RTM module is decoupled into the static code library and the RTM Wrapper in the embodiment of the invention, the RTM measurement is realized in the RTM Wrapper, and the RTM Wrapper can be easily transplanted into other projects.
Step S220, adding an interface function of a point to be measured in an RTM Wrapper, wherein the interface function is used for performing runtime measurement on the point to be measured;
specifically, the SWC in the AUTOSAR may be imported into other projects, where the behavior of the SWC is implemented by one or more Runnable entities (Runnable), which is the smallest code segment in the SWC, and finally mapped to a specific task of the operating system, and scheduled by the operating system to complete a corresponding function.
In order to improve the reusability of RTM, in the embodiment of the invention, an SWC Runneable function is arranged in the RTM Wrapper, and the Runneable function mainly has a start measurement start function and an end measurement stop function. The Runneable is utilized to realize an interface function of a point to be measured, and the purpose is to decouple the start and stop functions of the point to be measured configured by an RTM module of an AUTOSAR tool chain.
Step S230, adding a configuration module of the point to be measured in the RTM Wrapper, wherein the configuration module is used for inputting a test scheme of the point to be measured;
specifically, the configuration module is used for realizing the function of associating the input of the points to be measured with the output of the RTM Wrapper, and aims at being decoupled with the ordering of the measurement points and the quantity of the measurement points configured by the RTM module of the AUTOSAR tool chain. The configuration module may be configured based on a test scheme set by a user, for example, a test sequence of each measurement point, a run time threshold of each measurement point, and so on.
Step S240, adding an output module of the point to be measured in the RTM Wrapper, wherein the output module is used for outputting the RTM result of the point to be measured according to the test requirement;
specifically, the output module of the RTM Wrapper is a result of the RTM module based on the AUTOSAR tool chain, so that the associated RTM Wrapper configuration module is realized, and a measurement result is output. The occurrence time exceeding the threshold value can be increased in the result according to the test requirement set by the user, the result is output according to the measurement points configured by the RTM Wrapper user, and the CPU load rate of each measurement point is calculated based on each result.
Step S250, enabling the RTM Wrapper;
specifically, an AUTOSAR RTM is configured as a basic function, an enabling RTM module comprising a static code library and an RTM Wrapper correspondingly enables functions supporting RTM in the AUTOSAR BSW module. After the set program is brushed on a micro control unit (Microcontroller Unit, MCU) in the AUTOSAR to run, RTM measurement of each point to be measured can be started.
Step S260, obtaining the RTM result of the point to be measured from the output module.
Specifically, since the input module and the output module of the points to be measured are arranged in the RTM Wrapper, after the program is run, RTM measurement is performed on each point to be measured according to the test scheme set by the input module, and meanwhile, the test result is output according to the test requirement set by the output module, therefore, a user can obtain the measurement result of the RTM Wrapper from the output module, the results of each point to be measured in the RTM Wrapper are ordered according to the running result of the same CPU, ordering according to the maximum running time, ordering during average running time and the like can be customized, and the quick capture of the problems by a developer is facilitated.
In practical application, a user can acquire an RTM result of the point to be measured from the output module by using a universal measurement and calibration protocol XCP; or obtaining the RTM result of the point to be measured from the output module by using a debugging program debug.

According to the embodiment of the invention, the RTM module based on the AUTOSAR configuration tool chain develops the middle layer RTM Wrapper, the RTM module is configured once, and through the RTM Wrapper, which measurement points are enabled by a user in a customized way, the measurement point ordering configuration, the threshold configuration and the like can be realized, so that the running result of the measurement points can be seen after a period of automatic measurement, and the personnel are not required to be on duty. Under the condition that the software architecture is not changed, the measurement of all code segments can be met without adjusting the configuration of RTM and RTM Wrapper, the repeated adjustment work is reduced, and the development efficiency is improved.
On the basis of the above embodiment, further adding an interface function of a point to be measured in the RTM Wrapper includes:
if the point to be measured is a code segment, acquiring an interface function of the code segment from a software component SWC, wherein the interface function of the code segment comprises a code segment measurement start function and a code segment measurement end function;
adding the code segment measurement start function at the start position of the code segment;
and adding the code segment measurement ending function at the ending position of the code segment.
Specifically, the interface function of the obtained code segment in the software component SWC is rtm_startxx and rtm_stopxx, rtm_startxx is a code segment measurement start function, rtm_stopxx is a code segment measurement end function, XX is an identification of the code segment, rtm_startxx is set at a start position of the code segment, rtm_stopxx is set at an end position of the code segment, and rtm_startxx and rtm_stopxx are used for measuring the running time of the code segment between the two.
For example, if the code segment to be measured is rtmpt_user_core0_0, it may be set as:
Rtm_StartMeasurementFct(RtmConf(RtmPt_User_Core0_0))
code segment to be measured
Rtm_StopMeasurementFct(RtmConf(RtmPt_User_Core0_0))。
In the embodiment of the invention, aiming at RTM measurement of a code segment, an interface function is acquired from a software component, a measurement starting function is added at the starting position of the code segment, a measurement ending function is added at the ending position of the code segment, the interface function in SWC is added into an RTM Wrapper, the function of an AUTOSAR RTM module is optimized through an intermediate layer RTM Wrapper, the RTM module of the AUTOSAR tool chain is uncoupled into a static code library and configuration codes of the RTM Wrapper, the static code library is not required to be updated, and the configuration codes can be easily transplanted to other projects according to the needs.
On the basis of the above embodiments, further, adding an interface function of a point to be measured in the RTM Wrapper includes:
if the point to be measured is a Task, generating an interface function of the Task by using a run-time environment RTE of an AUTOSAR tool chain, wherein the interface function of the Task comprises a Task measurement start function and a Task measurement end function;
adding an interface function of the Task in a software component SWC of the RTM Wrapper;
associating the measurement start function to a start run position of the Task;
and associating the measurement ending function to the last execution position of the Task.
Specifically, the Task is an object in the AUTOSAR, and in the real-time operating system, each action performed is placed in the Task. The code needs to be triggered in what way, the code is placed in the corresponding Task, which contains a plurality of Runnable. In the prior art, a measurement point initial code of a Task is manually added in an RTM module to perform Task operation time measurement, however, after the AUTOSAR tool chain regenerates the code, the code can be cleaned, and development and debugging are inconvenient. In order to solve the problem, in the embodiment of the present invention, if the point to be measured is a Task, firstly, an interface function of the Task is generated by using a runtime environment RTE of an auto sar tool chain, where the interface function includes a Task measurement Start function and a Task measurement end function, that is, a Start run and a Stop run, the Start run is an rtm_startxx function of the Task, and the Stop run is an rtm_stopxx function of the Rtm, where XX represents a Task identifier.
Then, adding the rtm_startxx function and the rtm_stopxx function in the RTM Wrapper SWC, associating the rtm_startxx function to the start running position of the Task, that is, before the first Runnable associated with the Task, and associating the rtm_stopxx function to the last execution position of the Task, that is, after the last Runnable associated with the Task. Thus, for each Task, the order of Runnable runs rtm_startxx within the Task is the first run function and rtm_stopxx is the last run function.
Because the RTM interface function of the Task is arranged in the RTE code, the RTE can be updated each time, and cannot be cleaned, the RTM measurement of the Task is realized, the decoupling is carried out with the RTM by using a Runneable mode, manual adjustment is not needed, the interface function of the Task is configured in the SWC, the SWC can be led into different tool chains, repeated development is not needed, and the development efficiency is improved.
On the basis of the foregoing embodiments, further, the generating, by the runtime environment RTE using the auto sar tool chain, the interface function of the Task includes:
for each core, determining the SWC corresponding to the core;
determining a corresponding RTM starting interface function and a corresponding RTM ending interface function according to the Task corresponding to each SWC;

accordingly, before the enabling the RTM Wrapper, the method further includes:
and starting an RTM measuring switch of the Task.
Specifically, the Core is Core, and different MCU chips may have 1 Core,2 cores, etc., and one SWC is designed for each Core, for example, rtm_wrapper_core0, rtm_wrapper_core1, rtm_wrapper_core2, etc.
For each SWC, configuring the Task of the corresponding Core, determining a corresponding RTM Start interface function and RTM end interface function, i.e. determining an RTM Start interface function and an RTM Stop interface function of each Task, e.g. rtm_start_app_bsw_task_cork0_5 ms, rtm_stop_app_bsw_task_core0_5ms, etc. Masking the implementation functions of RTM in this way requires no adjustment in the design of SWC as BSW updates or other RTM modules change.
Then, the macro definition switch is used to set the RTM measurement switch of each Task, and because the RTM function is used for debugging, when the Debug version is used, the RTM measurement switch is turned on, and when the candidate Release version is used, the RTM function is turned off, so that the extra load is reduced.
In the embodiment of the invention, the intermediate layer RTM Wrapper is developed based on the AUTOSAR configuration tool chain RTM module, the Task measuring point configured by the RTM is isolated from the AUTOSAR tool chain RTE module, the function of measuring the Task is realized, the content of a test result is optimized through the logic processing of the intermediate layer RTM Wrapper, the problem analysis is convenient, the configuration is dynamically adjusted during running, and the development efficiency is improved.
On the basis of the above embodiments, further, the configuration module for adding the point to be measured in the RTM Wrapper, where the configuration module is configured to input a test solution of the point to be measured, and includes:
determining a point to be measured currently required to be measured in the points to be measured recorded by the RTM Wrapper according to a test scheme;
