The Automotive Test Platform (ATP) is a powerful hardware platform with interfaces for all conventional field

bus systems. It is aimed at customers who wish to develop specific application software for the automotive sector but do not have the relevant target hardware.

The hardware is based on a powerful microprocessor and supports a temperature range of -20° C to +70° C. The selected architecture ensures high data throughput via all interfaces with a low load on the main processor. The message packets can be assigned with a timestamp on all automotive bus system interfaces with an accuracy of 1 µs. This also applies to the analog and digital inputs and outputs.

Application interface
The Automotive Test Platform is based on a dual processor concept. The fieldbus controller is pre-configured and represents the interface to the supported fieldbuses. The customer’s own application runs on the main processor. Exchange of data between both processors is done via an FPGA. This is transparent for the user, as access to the fieldbus controller is mapped via a well-documented API supplied with the platform. The API provides all necessary functions for communicating via the various buses. In addition to functions for initialization, starting and stopping an interface, functions are also available for transmitting and receiving data.

Programming environment
Optionally, a SW development kit is provided for the ATP. This extends the Microsoft Visual Studio development environment for the SW development of applications on the ATP. Beside that, part of the contents of delivery are also other, helpful tools, which - for example - ensure the synchronization with the PC.

Diagnostic and transport protocols
As an option, fully programmed diagnostic and transport protocols can also be purchased for the ATP. These are supplied as loadable DLLs and can be used by the customer’s own application. It is possible to use higher protocols for communicating with the control units without the need for detailed knowledge of the protocols.

Series production
After successful implementation of the application, IXXAT also offers adaptation or optimization of the ATP design to the specific needs of the customer.

Diagnostic protocols/standards

• TP2.0 (CAN)
• ISO 15765-2 (CAN)
• ISO 14230-2 (K-Line)
• KWP2000
