AutosarFactory provides nice methods to read/create/modify AUTOSAR compliant arxml files.

• Clone the repository.

• Manually install the package.

  $ python setup.py install

use python3 if you have both python2 and python3 installed.

• Import the package autosarfactory to your python script.
• And, finally have fun with modelling AUTOSAR.

#Read a list of files
files = ['component.arxml', 'datatypes.arxml']
root, status = autosarfactory.read(files)

#Read a list of folders
folders = ['folder1', 'folder2']
root, status = autosarfactory.read(folders)

The read method processes the input files/folders and return the root node(with merged info of all the files). If folder is provided, the method does a deep search for the arxml files and reads in all the files in the folder. The status gives an info if the file/folder reading was successful.

newPack = autosarfactory.new_file('newFile.arxml', defaultArPackage = 'NewPack')

Creates a new arxml file with the given package name and returns the ARPackage object.

• If package name is not provided, default package name 'RootPackage' is used.
• The method raises FileExistsError if the given file already exist. To avoid this, please pass the argument overWrite as True.

Model elements have get_<attribute/reference> methods to access existing attribute and reference value.

For multi-references, the method returns a list of values

All the elements have set_<attribute/reference>methods to modify the attribute or reference value.

For multi-references, there also exists methods add_<reference>, remove_<reference>

All the parent classes have new_<element> methods to create an element.

rootPack = autosarfactory.new_file('newFile.arxml', defaultArPackage = 'RootPack')
newPack = rootPack.new_ARPackage('NewPack')
#new applicaton component
asw1 = newPack.new_ApplicationSwComponentType('asw1')
asw1.new_PPortPrototype('outPort')

#new senderRecever interface
srIf = newPack.new_SenderReceiverInterface('srif1')
srIf.new_DataElement('de1')

Once the file is read by the tool, its possible to access elements by path.

files = ['component.arxml', 'datatypes.arxml']
autosarfactory.read(files)
swc = autosarfactory.get_node('/Swcs/asw1')
uint8DataType = autosarfactory.get_node('/DataTypes/baseTypes/uint8')

The tool provides save method to save the changes made to the model.

files = ['component.arxml', 'datatypes.arxml']
autosarfactory.read(files)

rootPack = autosarfactory.new_file('newFile.arxml', defaultArPackage = 'RootPack')
newPack = rootPack.new_ARPackage('NewPack')

#new applicaton component
newcomp = newPack.new_ApplicationSwComponentType('newcomponent')
newcomp.new_PPortPrototype('outPort')

#new senderRecever interface
srIf = newPack.new_SenderReceiverInterface('srif1')
srIf.new_DataElement('de1')

#save changes
autosarfactory.save(['newFile.arxml'])

The save method accepts a list of file which needs to be saved. If no argument is provided, all the files(input, newly created) will be saved.

The tool provides saveAs method to save the changes made to the model into a single arxml file.

files = ['component.arxml', 'datatypes.arxml']
autosarfactory.read(files)

rootPack = autosarfactory.new_file('newFile.arxml', defaultArPackage = 'RootPack')
newPack = rootPack.new_ARPackage('NewPack')

#new applicaton component
newcomp = newPack.new_ApplicationSwComponentType('newcomponent')
newcomp.new_PPortPrototype('outPort')

#new senderRecever interface
srIf = newPack.new_SenderReceiverInterface('srif1')
srIf.new_DataElement('de1')

#save changes
autosarfactory.saveAs('mergedFile.arxml')

The package also includes a graphical visualizer for the Autosar models which can be simply opened by passing the autosar root to the method show_in_ui. For example:

files = ['component.arxml', 'datatypes.arxml']
root,status = autosarfactory.read(files)
autosar_ui.show_in_ui(root)

Please see below a screenshot of the visualizer.

The visualizer mainly consists of 4 views and a menu bar.

• Autosar Explorer - A simple tree which shows all elements in the model.
• Property view - Info about property and its corresponding values of the selected element in autosar explorer.
• Referenced by view - This views list elements which references the selected element in autosar explorer.
• Search view - Provision to search any elements in the model. The type of search can be selected through a combobox at the top of the view. There are 3 different types of search available: by the element short name, by a regular expression applied to the name of the element or by the Autosar type of the element.

The menu bar allows to switch the theme applied to the application at runtime and to exit the application. (This is planned to be extended with new menu options added in the future).

Please check the script inside the Examples folder which creates a basic communication matrix.
