Modeling Technical Architectures
The technical viewpoint is used to describe the structure and the properties of the hardware/software
platform of the system under design. This viewpoint provides the following models to define the
technical architecture of the system.
Note, that some of the models are mutually exclusive. Depending on the use case (e.g, code generation,
design-space exploration), different models (typically not all) are used to describe the technical
architecture of the system.
- Platform Architecture: A platform architecture
describes the hardware architecture and the resources of the system. It is required in all use cases
for which a technical architecture model is required. AutoFOCUS3 supports to model different hardware
- Task Architecture: This architecture enables to
specify the entities to which a logical architecture is mapped during the deployment to a
HW/SW platform (e.g., an RTOS).
- Partition Architecture: The partition
architecture abstracts the services provided by hypervisors (segregation of software entities by
means of time-space partitioning).
- Allocations: The allocation model is used to define
mappings between different architectural viewpoints of AutoFOCUS3.
- System schedule: A System Schedule is a container for
the schedules for all resources referenced by the given allocation.
