Target Hardware

The Target Hardware describes the actual physical processor that will be used for the modeled system. Setting up a specific Target Hardware for a system or a System Component customizes the code that will be generated for the exact specified Target Hardware and its drivers.

 

Each Target Hardware is defined in a DATAFLOW SDK and contains a specific hardware driver description that models the properties and behavior of the processor.

A DATAFLOW Software Development Kit SDK) contains all

• Header files,
• Binaries,
• Source code files,
• Target hardware settings and
• Definitions

For the DATAFLOW Designer, to generate code for a certain Target Hardware.

Using the same SDK enables the build (compiled from the DATAFLOW Designer generated code) and the DATAFLOW Simulator to interact and simulate the behavior of a specific hardware. An SDK can contain one or more target hardware configurations.

 

Hardware Targets can be defined using the DATAFLOW Simulator, or they can be installed in DATAFLOW Designer (see 4.4.1.1 Application Options) using predefined SDKs provided by IMT AG. When adding a Hardware Target to a specific component, the interface drivers defined for this Target Hardware will be available to assign to its child components from the Interface Toolbox.

 

Add Hardware Target

To add Target Hardware

1. Right-click a component
2. Select ‘Target Hardware > Add’ from the context menu.

Add Target Hardware

 

The selected item can be the System element, System Component or an Active Container. The Target Hardware is added to the selected element and all its child components. Target Hardware can be assigned to the root system element or once per tree branch.

Target Hardware Assignment

 

In the dialog that appears, a list of all Target Hardware items assigned to any System, System Components or Active Parts is displayed. The Target Hardware for the current item can be selected from the dropdown. The revision number and the list of drivers is presented below.

 

Once the Target Hardware has been created, the Target dialog is displayed to edit the configuration (see below).

Target Hardware Dialog

 

Edit Target Hardware

To edit a Target Hardware, select ‘Edit Target Hardware’ form the context menu. A dialog similar to the one for adding a Target Hardware initial setup appears.

 

Remove Target Hardware

To remove all Target Hardware from an element, right-click the element and select ‘Clear Target Hardware’ from the context menu.

Alternatively, the Target Hardware can also be removed in the Ribbon menu.

 

Target Hardware Driver Types

The following Target Hardware Driver Types are available for DATAFLOW Designer Projects.

Add Target Hardware Driver to Component

To add a Target Hardware Driver to a Component,

1. Go to the Interface Toolbox.
2. Expand the Drivers section (the drivers section is only available if Target Hardware was assigned to the corresponding Component)
3. Drag & Drop the required drivers onto the component in the Diagram Editor
