9 years ago Architecture verification review related to ADD document chapter and SCADE model structure
relating to chapter:
- 4.1 Manage_TrackSideInformation_Integration
- 4.1.1 Component Requirements
Finding:
- [ ] Filter in description missing
ADD:
In these sections, also a detailed definition of the concepts implemented on those interfaces is documented.
Finding:
- [ ] it should be stated, that only one information stream (balise or radio) is handled per cycle.
- 4.1.1 Interface
ADD:
An overview of the interface of component Manage_TrackSideInformation_Integration is shown in Figure 6.
Finding:
- [ ] Figure 6 does not show different input and output streams. It would be helpful to at least represent the information coming from different sources as separate inputs. As information are some subcomponents use information not used by those components before these inputs should directly be connected as input to the subcomponent.
- [ ] this SCADE model structure provides a very different impression of the basic data flows as the very clean figure 6. It would be helpful to restructure the SCADE model (specifically those local variables) to at least provide the same principal structure.
4.1.2.1 Inputs
Finding:
- [ ] 4.1.2.1.2 should be API_trackSide_Message
ADD:
4.1.2.1.7 tNvContact Description: For monitoring the safe radio connection, this national value is needed as an input. Source: Database
Finding:
- [ ] how is managing a safe radio connection related to this function. Please give a clear indication, why this input is needed.
- [ ] source database is in current architecture unclear
ADD: `4.1.2.1.8 lastRelevantEventTimestamp
Source: Database `
Finding:
- [ ] source database is in current architecture unclear
ADD: `4.1.2.1.10 inSupervisingRbcId
Source: Database Type: int Valid range of values [Complete list of valid values]`
Finding:
- [ ] type should be a combination of NID_C and NID_RBC
- [ ] source database is in current architecture unclear
- [ ] if this is an int the range should be defined
ADD: `4.1.2.1.12 q_nvlocacc
Source: Database`
Finding:
- [ ] source database is in current architecture unclear
Finding:
- [ ] further inputs existing in the SCADE model are missing (e.g. inActiveCab, inTrainDataValid, inFilterEvents, transitionPositionPassed)
4.1.2.2 Outputs
For most outputs
ADD:
Description [Brief description of the output]
And
Destination [Name of the destination component(s)]
Finding:
- [ ] it is unclear which information are provided by this output
- [ ] it is unclear which components uses this information, therefore no requirements can be verified
Within the design working package (WP3) the Architecture and Design Specifications are defined based mainly based on the Subset-26 and additional Subsets. In addition the User Stories derived for the Amsterdam-Utrecht Track have been used as a guideline. The main function _Manage_TrackSideInformationIntegration is responsible to collect and check the data received via BTM or Radio. Those information valid for the current train status are provided to the following kernel functions.
