Search for architectural element
finds an architectural element based on its universal unique identifier (UUID) or full
element = lookup(
finds an architectural element instance based on its universal unique identifier (UUID) or
instance = lookup(
This function is part of the instance programmatic interfaces that you can use to analyze
the model iteratively, element-by-element. The
instance refers to the
element instance on which the iteration is being performed.
Look Up Component by Path
This example shows how to find a component by path in a robot model.
arch = systemcomposer.loadModel("Robot"); component = lookup(arch,Path="Robot/Sensor")
component = Component with properties: IsAdapterComponent: 0 Architecture: [1x1 systemcomposer.arch.Architecture] Name: 'Sensor' Parent: [1x1 systemcomposer.arch.Architecture] Ports: [1x2 systemcomposer.arch.ComponentPort] OwnedPorts: [1x2 systemcomposer.arch.ComponentPort] OwnedArchitecture: [1x1 systemcomposer.arch.Architecture] Parameters: [0x0 systemcomposer.arch.Parameter] Position: [349 74 469 174] Model: [1x1 systemcomposer.arch.Model] SimulinkHandle: 10.0004 SimulinkModelHandle: 3.6621e-04 UUID: 'cfd62628-d365-47e4-8492-62cfeaa8dc15' ExternalUID: ''

Specify optional pairs of arguments as
the argument name and
Value is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Before R2021a, use commas to separate each name and value, and enclose

A System Composer™ architecture represents a system of components and how they interface with each other structurally and behaviorally.
Different types of architectures describe different aspects of systems. You can use views to visualize a subset of components in an architecture. You can define parameters on the architecture level using the Parameter Editor.
A System Composer model is the file that contains architectural information, including components, ports, connectors, interfaces, and behaviors.
Perform operations on a model:
A System Composer model is stored as an SLX file.

A 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 architectural 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. Transfer information between components with:
A 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:
Connectors 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.
Analysis is a method for quantitatively evaluating an architecture for certain characteristics. Static analysis analyzes the structure of the system. Static analysis uses an analysis function and parametric values of properties captured in the system model.
Use analyses to calculate overall reliability, mass roll-up, performance, or thermal characteristics of a system, or to perform a SWaP analysis.
An analysis function is a MATLAB® function that computes values necessary to evaluate the architecture using the properties of each element in the model instance.
Use an analysis function to calculate the result of an analysis.
An instance model is a collection of instances.
You can update an instance model with changes to a model, but
the instance model will not update with changes in active variants or model references. You can
use an instance model, saved in a
|Run Analysis Function|
An instance is an occurrence of an architecture model element at a given point in time.
An instance freezes the active variant or model reference of the component in the instance model.
