update
Syntax
Description
update(
updates a specification model
to mirror the changes in the architecture instance 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
Update Specification Model
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",true); 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
instance
— Architecture instance
architecture instance object
Architecture instance for which specification model is updated, specified as a
systemcomposer.analysis.ArchitectureInstance
object.

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 | 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 |
