slbuild

Build standalone executable or model reference target for model

Syntax

slbuild(model)
slbuild(model,buildSpec)
slbuild(___,Name,Value)

Description

example

slbuild(model) builds a standalone Simulink® Coder™ binary executable file for the specified model using the current model configuration settings. It also builds model reference coder targets for the referenced models.

If the specified model is not loaded, slbuild loads the model before initiating the build process.

If the model argument is a cell array of top models, slbuild builds an executable file for each model.

You cannot use slbuild to build subsystems.

example

slbuild(model,buildSpec) builds the files that correspond to the specified code generation action.

example

slbuild(___,Name,Value) builds files based on one or more name-value pair arguments.

Examples

Generate C code for model rtwdemo_rtwintro.

slbuild('rtwdemo_rtwintro')
% Same operation as ...
% slbuild('rtwdemo_rtwintro','StandaloneCoderTarget')

For the generic real-time (GRT) target, the coder generates these code files and places them in folders rtwdemo_rtwintro_grt_rtw and slprj/grt/_sharedutils.

If the following model configuration parameters settings apply, the coder generates additional results.

This example shows how to use slbuild to generate executable code for two models, sldemo_mdlref_depgraph and rtwdemo_counter. sldemo_mdlref_depgraph is a top model that references models. The example also shows how to build the referenced models in parallel.

Create a local folder.

if exist(fullfile('.','myTempFolder'),'dir')
    rmdir('myTempFolder','s')
end
mkdir myTempFolder
cd myTempFolder

Copy sldemo_mdlref_depgraph, which references models, to the local folder.

src_dir = fullfile(matlabroot, ...
                   'toolbox', ...
                   'simulink', ...
                   'simdemos', ...
                   'simfeatures', ...
                   'modelreference');
copyfile(fullfile(src_dir, ...
                  'sldemo_mdlref_depgraph.slx'), ...
                  '.');

Enable parallel building of models referenced by sldemo_mdlref_depgraph.

load_system('sldemo_mdlref_depgraph')
set_param('sldemo_mdlref_depgraph', ...
'EnableParallelModelReferenceBuilds', 'on');

Initialize MATLAB® workers for parallel building of referenced models.

set_param('sldemo_mdlref_depgraph', ...
          'ParallelModelReferenceMATLABWorkerInit', ...
          'Copy Base Workspace');

Build the models.

slbuild({'sldemo_mdlref_depgraph', 'rtwdemo_counter'})

In myTempFolder, the build process creates standalone executable files, sldemo_mdlref_depgraph.exe and rtwdemo_counter.exe.

For each model, in the Command Window, the build process displays a build summary.

Clean the model build area enough to trigger regeneration of the top model code at the next build.

slbuild('rtwdemo_rtwintro','CleanTopModel')

Generate code and build an executable image for rtwdemo_mdlreftop, which refers to model rtwdemo_mdlrefbot, regardless of model checksums and parameter settings.

slbuild('rtwdemo_mdlreftop','StandaloneCoderTarget', ...
    'ForceTopModelBuild',true)

Input Arguments

collapse all

If you specify the model name as a handle or character vector, the build process creates a standalone executable file or model reference target.

If you specify multiple models through a cell array of handles or character vectors, the build process applies buildSpec to each model in the cell array.

Example: gcs

buildSpec directs the code generator to perform the selected build action for the model and the build process:

  • Honors the setting of the Rebuild parameter on the Model Referencing pane of the Configuration Parameters dialog box.

  • Requires a Simulink Coder license only if you build a model reference Simulink Coder target, not if you build a model reference simulation target only.

The buildSpec argument must be one of the following.

buildSpecBuild Action

'StandaloneCoderTarget'

Builds a standalone Simulink Coder binary executable file for the specified model, using the current model configuration settings. It also builds model reference coder targets for the referenced models.

If the specified model is not loaded, slbuild loads it before initiating the build process.

'ModelReferenceSimTarget'

Builds a model reference simulation target (does not require a Simulink Coder license).

'ModelReferenceCoderTarget'

Builds a model reference Simulink Coder target and the corresponding model reference simulation target.

'ModelReferenceCoderTargetOnly'

Builds only a model reference Simulink Coder target.

'CleanTopModel'

Cleans the model build area enough to trigger regeneration of the top model code at the next build.

Example: 'ModelReferenceSimTarget'

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: 'UpdateThisModelReferenceTarget','Force'

Conditional rebuild option for the model reference build, specified as the comma-separated pair consisting of 'UpdateThisModelReferenceTarget' and 'Force', 'IfOutOfDateOrStructuralChange', or 'IfOutOfDate'.

This option applies only to the specified model, not to any models referenced by the specified model.

'UpdateThisModelReferenceTarget' ValueEquivalent Rebuild OptionRebuild Action

'Force'

Always

Unconditionally rebuilds the model.

'IfOutOfDateOrStructuralChange'

If any changes detected

Rebuilds the model if the build process detects any changes.

'IfOutOfDate'

If any changes in known dependencies detected

Rebuilds the model if the build process detects any changes in known dependencies of this model.

For more information on the different rebuild options, see Rebuild.

Example: 'UpdateThisModelReferenceTarget','Force'

Dependencies

To use this option, set buildSpec to 'ModelReferenceSimTarget', 'ModelReferenceCoderTarget', or 'ModelReferenceCoderTargetOnly'.

Data Types: char | string

Option to force the top model of the model hierarchy to build, specified as the comma-separated pair consisting of 'ForceTopModelBuild' and true or false.

Setting the value to true directs the code generator to generate code and build an executable image for the top model of the model hierarchy, regardless of model checksums and parameter settings.

Example: 'ForceTopModelBuild',true

Dependencies

To use this option, set buildSpec to 'StandaloneCoderTarget'.

Data Types: logical

Option to display the build information, specified as the comma-separated pair consisting of 'OpenBuildStatusAutomatically' and true or false.

To display build information in the Build Status window, specify true. The default is false. For more information about using the status window, see Monitor Parallel Building of Referenced Models (Simulink Coder).

The Build Status window supports parallel builds of referenced model hierarchies. Do not use the Build Status window for serial builds.

Dependencies

To use this option, set buildSpec to 'StandaloneCoderTarget'.

Data Types: logical

Option to build model reference simulation targets, specified as the comma-separated pair consisting of 'IncludeModelReferenceSimulationTargets' and true or false.

Dependencies

To use this option, set buildSpec to 'StandaloneCoderTarget'.
