Syntax

update(instance)

Description

example

update(instance) updates a specification model to mirror the changes in the architecture instance instance. The update 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

collapse all

Update the specification model to mirror the changes in the 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

Create a new model. Apply the profile to the model. Apply the stereotype to the architecture. Instantiate all stereotypes in a profile.

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

Set a new value for the "dataRate" property on the architecture instance.

instance.setValue("LatencyProfile.LatencyBase.dataRate",5);

Update the specification model according to the architecture instance.

instance.update

Get the new value of the "dataRate" property on the architecture.

value = model.Architecture.getPropertyValue("LatencyProfile.LatencyBase.dataRate")
value =

    '5'

Input Arguments

collapse all

Architecture instance for which specification model is updated, specified as a systemcomposer.analysis.ArchitectureInstance object.

Definitions

TermDefinitionApplicationMore 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.
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.
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.
