Abstract

During the preparation of the documentation for the SKA Low Frequency Aperture Array, a system modelling tool has been used to aid the system design. The tool adopts the SysML graphics language to describe the system product breakdown structure, to identify the internal and external connection between its elements, the interfaces that characterise the system, and to describe the functions and the data flow associated with each element. The derived diagrams were used in the documents being prepared for the instrument critical design review.

The main advantage in applying such an approach is the ease of modification and maintenance of the documentation. As the elements composing the system and their relations are defined inside the abstract model, any change is automatically reflected in a consistent ways in all diagrams describing the instrument.
