Extract atomic subsystem or subchart contents into new model

Syntax

newModel = slvnvextract(subcomponent)
newModel = slvnvextract(subcomponent,showModel)
newModel = slvnvextract(modelmissingslfunctiondef)
newModel = slvnvextract(modelmissingslfunctiondef, showModel)

Description

newModel = slvnvextract(subcomponent) extracts the contents of the Atomic Subsystem block or atomic subchart subcomponent and creates a model. slvnvextract returns the name of the new model in newModel. If the model name already exists,slvnvextract uses the subsystem or subchart name for the model name, appending a numeral to the model name.

Note

If an atomic subchart calls an exported graphical function that is outside the subchart, slvnvextract creates the model, but the new model does not compile.

newModel = slvnvextract(subcomponent,showModel) opens the extracted model if you set showModel to true. The extracted model is loaded only if you set showModel to false.

newModel = slvnvextract(modelmissingslfunctiondef) extracts a stub model for the model modelmissingslfunctiondef which has missing Simulink function definitions for the Simulink® Design Verifier™ to analyze. Returns the name of the new model in newModel. sldvextract uses the input model name with a suffix SldvStub for the extracted model name, appending a numeral to the model name if that model name already exists.

newModel = slvnvextract(modelmissingslfunctiondef, showModel) opens the extracted model if you set showModel to true. Extracted model will be only loaded if showModel is set to false.

This example shows how to extract an atomic subsystem from a model and copy it to a new model using slvnvextract.

Load the sldemo_lct_bus model.

modelName = 'slcoverage_lct_bus';
load_system(modelName);
load slcoverage_lct_data.mat

The slcoverage_lct_bus model has an S-Function. Build the S-Function by using legacy_code.

def = legacy_code('initialize');
def.SFunctionName = 'slcoverage_sfun_counterbus';
def.OutputFcnSpec = ...
    ['void counterbusFcn(COUNTERBUS u1[1], '...
    'int32 u2, COUNTERBUS y1[1], int32 y2[1])'];
def.HeaderFiles   = {'counterbus.h'};
def.SourceFiles   = {'counterbus.c'};
def.Options.supportCoverage = true;
legacy_code('generate_for_sim', def);
