systemcomposer.exportModel

Export model information as MATLAB tables

Description

example

[exportedSet] = systemcomposer.exportModel(modelName) exports model information for components, ports, connectors, port interfaces, and requirement links, with a domain field to be imported into MATLAB® tables. The exported tables have prescribed formats to specify model element relationships, stereotypes, and properties. For more information on the import structure, see the importModel function and Import and Export Architecture Models.

Examples

To export a model, pass the model name as an argument to the exportModel function. The function returns a structure containing five tables: components, ports, connections, portInterfaces, and requirementLinks, with a domain field returned as 'System' for architecture models and 'Software' for software architecture models.

exportedSet = systemcomposer.exportModel('exMobileRobot')

exportedSet =

      portInterfaces: [3×9 table]
    requirementLinks: [4×15 table]
              domain: 'System'

Definitions

TermDefinitionApplicationMore Information
architectureA System Composer™ architecture represents a system of components and how they interface with each other structurally and behaviorally. You can represent specific architectures using alternate views.

Different types of architectures describe different aspects of systems:

  • Functional architecture describes the flow of data in a system.

  • Logical architecture describes the intended operation of a system.

  • Physical architecture describes the platform or hardware in a system.

Compose Architecture Visually
modelA System Composer model is the file that contains architectural information, including components, ports, connectors, interfaces, and behaviors.

Perform operations on a model:

  • Extract the root-level architecture contained in the model.

  • Apply profiles.

  • Link interface data dictionaries.

  • Generate instances from model architecture.

System Composer models are stored as SLX files.

Create an Architecture Model with Interfaces and Requirement Links
componentA component is a nontrivial, nearly independent, and replaceable part of a system that fulfills a clear function in the context of an architecture. A component defines an architecture element, such as a function, a system, hardware, software, or other conceptual entity. A component can also be a subsystem or subfunction.Represented as a block, a component is a part of an architecture model that can be separated into reusable artifacts.Components
portA port is a node on a component or architecture that represents a point of interaction with its environment. A port permits the flow of information to and from other components or systems.

There are different types of ports:

  • Component ports are interaction points on the component to other components.

  • Architecture ports are ports on the boundary of the system, whether the boundary is within a component or the overall architecture model.

Ports
connectorConnectors are lines that provide connections between ports. Connectors describe how information flows between components or architectures.A connector allows two components to interact without defining the nature of the interaction. Set an interface on a port to define how the components interact.Connections

interface data dictionaryAn interface data dictionary is a consolidated list of all the interfaces and value types in an architecture and where they are used.

Local interfaces on a System Composer model can be saved in an interface data dictionary using the Interface Editor.

Interface dictionaries can be reused between models that need to use a given set of interfaces, elements, and value types. Data dictionaries are stored in separate SLDD files.

data interfaceA data interface defines the kind of information that flows through a port. The same interface can be assigned to multiple ports. A data interface can be composite, meaning that it can include data elements that describe the properties of an interface signal.Data interfaces represent the information that is shared through a connector and enters or exits a component through a port. Use the Interface Editor to create and manage data interfaces and data elements and store them in an interface data dictionary for reuse between models.Create an Architecture Model with Interfaces and Requirement Links
data elementA data element describes a portion of an interface, such as a communication message, a calculated or measured parameter, or other decomposition of that interface.

Data interfaces are decomposed into data elements:

  • Pins or wires in a connector or harness.

  • Messages transmitted across a bus.

  • Data structures shared between components.

value typeA value type can be used as a port interface to define the atomic piece of data that flows through that port and has a top-level type, dimension, unit, complexity, minimum, maximum, and description.You can also assign the type of data elements in data interfaces to value types. Add value types to data dictionaries using the Interface Editor so that you can reuse the value types as interfaces or data elements.Create Value Types as Interfaces
owned interfaceAn owned interface is a locally defined interface that is local to a specific port and not shared in a data dictionary or the model dictionary.Create an owned interface to represent a value type or data interface that is local to a port.Define Owned Interfaces Local to Ports
adapterAn adapter helps connect two components with incompatible port interfaces by mapping between the two interfaces. An adapter can also act as a unit delay or rate transition. Use the Adapter block to implement an adapter.

With an adapter, you can perform functions on the Interface Adapter dialog:

  • Create and edit mappings between input and output interfaces.

  • Apply an interface conversion UnitDelay to break an algebraic loop.

  • Apply an interface conversion RateTransition to reconcile different sample time rates for reference models.

requirementsRequirements are a collection of statements describing the desired behavior and characteristics of a system. Requirements ensure system design integrity and are achievable, verifiable, unambiguous, and consistent with each other. Each level of design should have appropriate requirements.To enhance traceability of requirements, link system, functional, customer, performance, or design requirements to components and ports. Link requirements to each other to represent derived or allocated requirements. Manage requirements from the Requirements Manager on an architecture model or through custom views. Assign test cases to requirements using the Test Manager for verification and validation.Link and Trace Requirements
requirement setA requirement set is a collection of requirements. You can structure the requirements hierarchically and link them to components or ports.Use the Requirements Editor to edit and refine requirements in a requirement set. Requirement sets are stored in .slreqx files. You can create a new requirement set and author requirements using Simulink® Requirements™, or import requirements from supported third-party tools.Manage Requirements
requirement linkA link is an object that relates two model-based design elements. A requirement link is a link where the destination is a requirement. You can link requirements to components or ports.View links using the Requirements perspective in System Composer. Select a requirement in the Requirements Browser to highlight the component or the port to which the requirement is assigned. Links are stored externally as .slmx files.
test harnessA test harness is a model that isolates the component under test, with inputs, outputs, and verification blocks configured for testing scenarios. You can create a test harness for a model component or for a full model. A test harness gives you a separate testing environment for a model or a model component.Create a test harness for a System Composer component to validate simulation results and verify design. The Interface Editor is accessible in System Composer test harness models to enable behavior testing and implementation-independent interface testing.
