Purpose

The Performance viewpoint enables to simply describe the non-functional aspect of performance in Capella.

Scope

Performance information can be added on a Logical/PhysicalFunction, Logical/PhysicalFunctionExchange, and Logical/PhysicalFunctionalChain elements or graphically in LAB/PAB diagrams.

Principles

On a Functional Exchange or Function, an "Execution Time" indicator defines the execution time. A "Time Limit" defines the maximal execution accepted by a Functional Chain.

The Total Execution Time of a Functional Chain is the sum of the Execution Time of all the Functional Exchange and Function elements which compose the Functional Chain.

Graphically, when:


Practice

The Basic Performance viewpoint enriches the Capella palette with a new section composed of two icons:

Use of Function Time Consumption:

Use of Functional Chain Consumption:
