Map Simulink block signal to AUTOSAR variable



mapSignal(slMap,slPortHandle,arVarType) maps the named or test-pointed Simulink® block signal associated with outport port handle slPortHandle to an AUTOSAR variable of type arVarType for AUTOSAR run-time calibration. AUTOSAR variable types include ArTypedPerInstanceMemory and StaticMemory.

mapSignal(slMap,slPortHandle,arVarType,Name,Value) specifies additional properties for an AUTOSAR ArTypedPerInstanceMemory or StaticMemory variable by using one or more Name,Value pair arguments.

Set AUTOSAR mapping and property information for the Simulink block signals for blocks RelOpt and Sum in example model autosar_swc_counter.

hModel = 'autosar_swc_counter';
slMap = autosar.api.getSimulinkMapping(hModel);

portHandles = get_param('autosar_swc_counter/RelOpt','portHandles');
outportHandle = portHandles.Outport;
arMappedTo = getSignal(slMap,outportHandle)
arValue = getSignal(slMap,outportHandle,'SwCalibrationAccess')

portHandles = get_param('autosar_swc_counter/Sum','portHandles');
outportHandle = portHandles.Outport;
arMappedTo = getSignal(slMap,outportHandle)
arValue = getSignal(slMap,outportHandle,'SwCalibrationAccess')

Input Arguments

collapse all

Simulink to AUTOSAR mapping information for a model, previously returned by slMap = autosar.api.getSimulinkMapping(model). model is a handle, character vector, or string scalar representing the model name.

Example: slMap

Outport port handle for a named or test-pointed Simulink block signal to set AUTOSAR mapping information for. Use MATLAB® commands to construct the outport port handle. For example, for a Relational Operator block named RelOpt:

portHandles = get_param('autosar_swc_counter/RelOpt','portHandles');
outportHandle = portHandles.Outport;

Example: outportHandle

Type of AUTOSAR variable to map the specified Simulink block signal to. Valid AUTOSAR variable types include ArTypedPerInstanceMemory, StaticMemory, and Auto. To accept software mapping defaults, specify Auto.

Example: 'StaticMemory'

Name-Value 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: 'SwCalibrationAccess','ReadWrite' specifies read-write access to the variable for run-time calibration.

Specify display format for the AUTOSAR variable. AUTOSAR display format specifications control the width and precision display for measurement and calibration data. For more information, see Configure DisplayFormat.

Example: 'DisplayFormat','%2.6f'

Specify whether to include C type qualifier volatile in generated code for the AUTOSAR variable.

Example: 'IsVolatile','true'

Optionally specify an AUTOSAR additional native type qualifier to include in generated code for the AUTOSAR variable.

Example: 'Qualifier','test_qualifier'

Specify a short name for the AUTOSAR variable. If unspecified, ARXML export generates a short name, which can differ from the signal name.

Example: 'ShortName','SM_equal_to_count'

Specify a SwAddrMethod name that is valid for the AUTOSAR variable. Code generation uses the SwAddrMethod name to group AUTOSAR variables in a memory section for access by measurement and calibration tools. For a list of valid SwAddrMethod values for the variable, see the Code Mappings editor, Signals/States tab. For more information, see Configure SwAddrMethod.

Example: 'SwAddrMethod','VAR'

Specify how measurement and calibration tools can access the AUTOSAR variable. Valid access values include ReadOnly, ReadWrite, and NotAccessible. For more information, see Configure SwCalibrationAccess.

Example: 'SwCalibrationAccess','ReadWrite'
