## 4. 功能概述
|
||||
|
||||
此模块的目的是提供一个基础架构,用于在 AUTOSAR 标准软件平台中集成/转换微控制器制造商特定的启动和关闭测试(例如 BIST)测试结果/状态。
|
||||
|
||||
此模块的基本功能包括:从 MSTP 收集测试结果/状态、配置 MSTP 测试、启动测试执行、向 EcuM 模块和应用 SWC 提供 MSTP 测试状态以评估系统行为的测试结果。
|
||||
|
||||
HTMSS 模块集成在 AUTOSAR BSW 服务层级别。下图显示了 HTMSS 模块在 AUTOSAR 软件平台中的功能集成。

|
||||
|
||||
HTMSS 模块预集成需求:
|
||||
|
||||
- 应能在开发中的设备上运行微控制器专用测试包(MSTP)启动和关闭测试。
|
||||
- 测试结果/状态可由 HTMSS 模块访问。
|
||||
- 应能通过 HTMSS 模块配置 MSTP 启动和关闭测试。
|
||||
|
||||
### 4.1 功能需求
|
||||
|
||||
#### 4.1.1 HTMSS 和 MSTP 测试的配置需求
|
||||
|
||||
##### 4.1.1.1 [SRS_HTMSS_00001] HTMSS 应允许配置启动和关闭测试
|
||||
|
||||
```
|
||||
Type: Valid
|
||||
Description: It shall be possible to configure the microcontroller specific
|
||||
start up and shutdown tests
|
||||
Rationale: It is necessary to be able to select and configure the tests
|
||||
based on HTMSS integrator requirements
|
||||
Use Case: The HTMSS configuration developer maps the microcontroller
|
||||
specific tests in the module configuration set
|
||||
Dependencies: [SRS_HTMSS_00002]
|
||||
Supporting Material:
|
||||
⌋( FS_HTMSS_00001)
|
||||
```
|
||||
|
||||
##### 4.1.1.2 [SRS_HTMSS_00002] HTMSS 应允许在单个硬件资源级别上配置测试
|
||||
|
||||
```
|
||||
Type: Valid
|
||||
Description: It shall be possible to test the individual hardware resources
|
||||
(e.g. selected via module / channel ID) on the given hardware
|
||||
Rationale: The given hardware may contain two hardware unit for the
|
||||
resource considered under test (e.g. 2 separate ADC hardware
|
||||
units). In this example, it may be possible to test/obtain
|
||||
result for each ADC unit individually.
|
||||
Use Case: The user may need to test all the hardware resources under
|
||||
test (used and unused), since certain microcontroller
|
||||
manufacturer may state that there is no guarantee that errors
|
||||
in unused hardware resource do not propagate or have
|
||||
influence on the rest of the microcontroller.
|
||||
Dependencies:
|
||||
Supporting Material:
|
||||

|
||||
```
|
||||
|
||||
#### 4.1.2 HTMSS 的主要功能
|
||||
|
||||
##### 4.1.2.1 [SRS_HTMSS_00003] HTMSS 应提供服务以收集 MSTP 测试结果
|
||||
|
||||
```
|
||||
Type: Valid
|
||||
Description: The HTMSS shall collect and provide the test results of all
|
||||
executed tests
|
||||
Rationale: The MSTP test results shall be accessible
|
||||
Use Case: Having the tests results details, shall convey the fault status
|
||||
of the microcontroller.
|
||||
Dependencies: [SRS_HTMSS_00001], [SRS_HTMSS_00002]
|
||||
Supporting Material:
|
||||
⌋( FS_HTMSS_00001)
|
||||
```
|
||||
|
||||
##### 4.1.2.2 [SRS_HTMSS_00004] HTMSS 应提供机制以与应用层软件共享测试结果
|
||||
|
||||
```
|
||||
Type: Valid
|
||||
Description: The current MSTP test results shall be provided to the
|
||||
application layer software during RUN time
|
||||
Rationale: The applicative software evaluates and react on critical
|
||||
errors to ensure the safe state (e.g. change from normal
|
||||
run time to a degradation mode)
|
||||
Use Case: The application software shall maintain the safe state
|
||||
based on the test results. E.g. a critical error judged
|
||||
according to the safety goals of the system may result in
|
||||
going to a safe state
|
||||
Dependencies: [SRS_HTMSS_00001], [SRS_HTMSS_00002], [SRS_HTMSS_00004]
|
||||
Supporting Material:

||||
|
||||
#### 4.1.3 HTMSS 的 ECUM 集成功能
|
||||
|
||||
以下 HTMSS 模块函数应集成在 ECUM 模块中。
|
||||
|
||||
##### 4.1.3.1 [SRS_HTMSS_00005] HTMSS 应提供服务以在 ECUM 启动阶段配置/初始化 MSTP 测试
|
||||
|
||||
```
|
||||
Type: Valid
|
||||
Description: It shall be possible to configure the start up and shutdown
|
||||
tests during the ECUM start up phase via HTMSS interface
|
||||
Rationale: Initialization is required to pre-initialize the variables of
|
||||
HTMSS and the MSTP tests
|
||||
Use Case: During MCU start up the hardware is initialised to execute
|
||||
MSTP tests
|
||||
Dependencies: [SRS_HTMSS_00001], [SRS_HTMSS_00002]
|
||||
Supporting Material:
|
||||
⌋( FS_HTMSS_00001)
|
||||
```
|
||||
|
||||
##### 4.1.3.2 [SRS_HTMSS_00006] HTMSS 应提供服务以触发测试执行
|
||||
|
||||
```
|
||||
Type: Valid
|
||||
Description: It shall be possible to trigger the start up tests during the
|
||||
ECUM start up phase and shutdown tests during ECUM shut
|
||||
down phase via HTMSS provided service function
|
||||
Rationale: The start up tests shall be performed during ECUM start up
|
||||
phase and the shut down tests shall be performed during
|
||||
the ECUM shutdown phase
|
||||
Use Case: During ECU start up and shutdown phase the configured
|
||||
MSTP tests are triggered for its execution

#### 4.1.4 故障操作
|
||||
|
||||
##### 4.1.4.1 [SRS_HTMSS_00007] HTMSS 应提供 callout 选项以处理测试失败条件
|
||||
|
||||
```
|
||||
Type: Valid
|
||||
Description: On test failure (critical error conditions) it shall be
|
||||
possible to initiate error hooks as callout functions.
|
||||
Rationale: e.g. React to test failure to initiate ECU reset, safe state
|
||||
etc...
|
||||
Use Case: The ECU software need to react to the test failures by
|
||||
preparing the system state (e.g. reset, halt, safe state)
