Save architecture instance

Syntax

save(instance,fileName)

Description

save(instance,fileName) saves an architecture instance to a MAT file. The save method is part of the systemcomposer.analysis.ArchitectureInstance class.

Note

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.

Examples

Save Architecture Instance to MAT File

Create a profile for latency characteristics, and save the profile.

profile = systemcomposer.profile.Profile.createProfile("LatencyProfile");

latencybase = profile.addStereotype("LatencyBase");
latencybase.addProperty("latency",Type="double");
latencybase.addProperty("dataRate",Type="double",DefaultValue="10");

connLatency = profile.addStereotype("ConnectorLatency",...
Parent="LatencyProfile.LatencyBase");
connLatency.addProperty("secure",Type="boolean");
connLatency.addProperty("linkDistance",Type="double");

nodeLatency = profile.addStereotype("NodeLatency",...
Parent="LatencyProfile.LatencyBase");
nodeLatency.addProperty("resources",Type="double",DefaultValue="1");

portLatency = profile.addStereotype("PortLatency",...
Parent="LatencyProfile.LatencyBase");
portLatency.addProperty("queueDepth",Type="double");
portLatency.addProperty("dummy",Type="int32");

profile.save

Instantiate all stereotypes in a profile.

model = systemcomposer.createModel("archModel");
systemcomposer.openModel("archModel");
instance = instantiate(model.Architecture,"LatencyProfile","NewInstance");

Save the architecture instance.

instance.save("InstanceFile")

Input Arguments

instance — Architecture instance

architecture instance object

Architecture instance to be saved, specified as a systemcomposer.analysis.ArchitectureInstance object.

fileName — MAT file to save instance

character vector | string

MAT file to save instance, specified as a character vector or string.

Example: "InstanceFile"

Data Types: char | string

Term	Definition	Application	More Information
Analysis	Static analysis analyzes the structure of the system to quantitatively evaluate an architecture for certain characteristics. Static analysis uses an analysis function and parametric values of properties and parameters 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 size, weight, and power (SWaP) analysis to increase efficiency.	Analyze Architecture Model Properties with Analysis Function Analyze Architecture Simple Roll-Up Analysis Using Robot System with Properties
Analysis function	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 and instance-specific parameters at the component and architecture levels.	Use an analysis function to calculate the result of an analysis.	Analysis Function Constructs Write Analysis Function
Instance model	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 MAT file, of a System Composer™ architecture model for analysis.	Run Analysis Function
Instance	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.	Create a Model Instance for Analysis
