Concept: TADL Guides
A TADL guide describes which language elements can be used in a specific task of the TIMMO-2-USE methodology to describe timing information. TADL guides, therefore, represent a link between the technical results of the work packages 2 (Language) and 4 (Methodology).

Main Description

A TADL guide describes which language elements can be used in a specific task of the TIMMO-2-USE methodology to describe timing information. TADL guides, therefore, represent a link between the technical results of the work packages 2 (Language) and 4 (Methodology).

 

 

Figure 1 - Structure of TADL guides

Figure 1 shows the overall structure of the TADL guides. Basically, each TADL guide can be seen as timing property or timing requirement depending on the role it is referenced in. Then, there is the actual description of the TADL2 language concept. Examples for TADL guides that were created are:

·         Execution time (Worst-case, Best-case,  Simulated,  Measured)

·         End-to-end Latency

·         Sampling Rates

·         Time Budget

·         Response Time

·         Communication Delay

·         Slack

·         Repetition pattern

·         Synchronization

Each TADL guide references the TADL elements, i.e. classes of the TADL2 meta model, that are necessary to use the TADL guide. Examples are events, event chains, etc.

In order to maximize the usefulness of the TADL guide, the guide for the same TADL2 concept is instantiated for each abstraction level it is applicable for. Additionally, each TADL guide is completed with context specific model elements, like the list of relevant EAST-ADL and AUTOSAR events, and a context specific example.
