systemcomposer.analysis.deleteInstance

Delete architecture instance

Since R2019a

Syntax

systemcomposer.analysis.deleteInstance(instance)

Description

systemcomposer.analysis.deleteInstance(instance) deletes an existing instance.

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

Delete Architecture Instance

Create a profile for latency characteristics and save it.

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 the profile.

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

Delete the architecture instance.

systemcomposer.analysis.deleteInstance(instance);

Input Arguments

instance — Architecture instance

architecture instance object

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

Definitions

Term	Definition	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 analyses to calculate overall reliability, mass roll-up, performance, or thermal characteristics of a system, or to perform a SWaP analysis.	Analyze Architecture Model 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.	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
