This example shows an instantiation for analysis for a system with latency in its wiring. The materials used are copper, fiber, and WiFi.

Create a Latency Profile with Stereotypes and Properties

Create a System Composer profile with a base, connector, component, and port stereotype. Add properties with default values to each stereotype as needed for analysis.

profile = systemcomposer.profile.Profile.createProfile('LatencyProfile'）；% Add base stereotype with propertieslatencybase = profile.addStereotype('LatencyBase'）；latencybase.addproperty（'latency','类型','double'）；latencybase.addproperty（“塔尔ate','类型','double','默认值','10'）；% Add connector stereotype with propertiesconnLatency = profile.addStereotype('ConnectorLatency','Parent',...'LatencyProfile.LatencyBase'）；connLatency.addProperty('secure','类型',“布尔人”,'默认值','true'）；connLatency.addProperty('linkDistance','类型','double'）；％添加具有属性的组件刻板印象nodeLatency = profile.addStereotype('NodeLatency','Parent',...'LatencyProfile.LatencyBase'）；nodelatency.addproperty（'resources','类型','double','默认值','1'）；% Add port stereotype with propertiesportLatency = profile.addStereotype('PortLatency','Parent',...'LatencyProfile.LatencyBase'）；portLatency.addProperty('queuedepth','类型','double','默认值','4.29'）；portLatency.addProperty('假','类型','int32'）；

使用分析功能实例化

Create a new model and apply the profile. Create components, ports, and connections in the model. Apply stereotypes to the model elements. Finally, instantiate using the analysis function.

model = systemcomposer.createModel('archModel',true);% Create new modelarch = model.Architecture; model.applyProfile('LatencyProfile'）；％将轮廓应用于模型% Create components, ports, and connections组件= AddComponent（Arch，{'Sensor','Planning','Motion'}）;sensorports = addport（组件（1）.architecture，{'MotionData','SensorData'}，{'in','out'}）;planningPorts = addPort(components(2).Architecture,{'SensorData','MotionCommand'}，{'in','out'}）;motionPorts = addPort(components(3).Architecture,{'MotionCommand','MotionData'}，{'in','out'}）;c_sensordata = connect（Arch，组件（1），组件（2））;c_motiondata = connect（Arch，组件（3），组件（1））;C_MotionCommand = Connect（Arch，组件（2），组件（3））;% Clean up canvasSimulink.BlockDiagram.arrangeSystem('archModel'）；% Batch apply stereotypes to model elementsbatchApplyStereotype(arch,'Component','LatencyProfile.NodeLatency'）；batchApplyStereotype(arch,'Port','LatencyProfile.PortLatency'）；batchApplyStereotype(arch,'Connector','LatencyProfile.ConnectorLatency'）；％使用分析功能实例化实例=实例（model.Architecture，'LatencyProfile','NewInstance',...'Function'，@calculatelatency，'Arguments','3','Strict',true,...“标准化”,false,'方向','PreOrder')

instance = ArchitectureInstance with properties: Specification: [1x1 systemcomposer.arch.Architecture] IsStrict: 1 NormalizeUnits: 0 AnalysisFunction: @calculateLatency AnalysisDirection: PreOrder AnalysisArguments: '3' ImmediateUpdate: 0 Components: [1x3 systemcomposer.analysis.ComponentInstance] Ports: [0x0 systemcomposer.analysis.PortInstance] Connectors: [1x3 systemcomposer.analysis.ConnectorInstance] Name: 'NewInstance'

Inspect Component, Port, and Connector Instances

Get properties from component, port, and connector instances.

defaultresources = instance.components（1）.getValue（'LatencyProfile.Nodelatency.Resources')

defaultResources = 1

defaultsecure = instance.connectors（1）.getValue（'LatencyProfile.ConnectorLatency.secure')

defaultSecure =logical1

defaultQueueDepth = instance.Components(1).Ports(1).getValue('litencyProfile.portlatency.queuedepth')

defaultQueueDepth = 4.2900

Battery Sizing and Automotive Electrical System Analysis

Open Live Script

Overview

This example shows how to model a typical automotive electrical system as an architectural model and run primitive analysis. The elements in the model can be broadly grouped as either source or load. Various properties of the sources and loads are set as part of the stereotype. The example uses theiteratemethod of the specification API to iterate through each element of the model and run analysis using the stereotype properties.

Structure of the Model

发动机运行时，发电机为电池充电。电池以及发电机支持车辆中的电气负载，例如ECU，无线电和车身控制。万博1manbetx电感载荷等电动机和其他线圈具有InRushCurrentstereotype property defined. Based on the properties set on each component, the following analyses are performed:

全部的keyOffload.
Number of days required forkeyOffloadto discharge 30% of the battery.
全部的曲柄当前的。
全部的Cranking当前的。
Ability of the battery to start the vehicle at 0°F based on the battery cold cranking amps (CCA). The discharge time is computed based on Puekert coefficient (k), which describes the relationship between the rate of discharge and the available capacity of the battery.

加载模型并运行分析

archModel = systemcomposer.openModel('scExampleAutomotiveElectricalSystemAnalysis'）；% Instantiate battery sizing class used by the analysis function to store% analysis results.objcomputeBatterysized = ComputeBatterysized;% Run the analysis using the iterator.archModel.iterate('Topdown'，@computeload，objcomputeBatterysizing）;% Display analysis results.objcomputeBatterySizing.displayResults;

全部的keyOffload: 158.708 mA Number of days required for KeyOffLoad to discharge 30% of battery: 55.789. Total CrankingInRush current: 70 A Total Cranking current: 104 A CCA of the specifed battery is sufficient to start the car at 0 F.

定义s

Term	定义	Application	More Information
analysis	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 analysis to calculate overall reliability, mass roll-up, performance, or thermal characteristics of a system, or to perform a SWaP analysis.	Analyze Architecture
instance	实例是在给定时间点的架构模型的发生。	You can update an instance with changes to a model, but the instance will not update with changes in active variants or model references. You can use an instance, saved in an`.MAT`file, of a System Composer™ architecture model for analysis.	Create a Model Instance for Analysis

Term	定义	Application	More Information
建筑学	系统作曲家体系结构代表组件系统以及它们如何在结构和行为上相互接口。您可以使用替代视图表示特定的体系结构。	Different types of architectures describe different aspects of systems: Functional architecturedescribes the flow of data in a system. Logical architecture描述系统的预期操作。 Physical architecturedescribes the platform or hardware in a system.	Compose Architecture Visually
model	系统作曲家模型是包含架构信息的文件，包括组件，端口，连接器，接口和行为。	Perform operations on a model: Extract the root level architecture contained in the model. Apply profiles. 链接接口数据字典。 Generate instances from model architecture. 系统作曲家模型被存储为`.slx`files.	Create an Architecture Model
component	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 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.	成分
port	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: 组件端口are interaction points on the component to other components. 建筑端口are ports on the boundary of the system, whether the boundary is within a component or the overall architecture model.	端口
connector	Connectors are lines that provide connections between ports. Connectors describe how information flows between components or architectures.	连接器允许两个组件相互作用，而无需定义交互的性质。在端口上设置一个接口以定义组件如何交互。	连接
