• Selection of bypass model inputs and outputs from ECU description file (ASAP2)
• Convenient variable browser with search options and hierarchical representation
• Automatic handling of conversion formulas and selection of bypass hooks within the blockset
• Configurable failure checking and data consistency mechanism
• Supports service-based bypassing via DPMEM PODs, DCI-GSI1, XCP on CAN, CCP, and XCP on Ethernet (UDP/IP)¹⁾

Application Areas
For developing ECU functions by means of the external bypass approach, it is usually necessary to configure the bypass interface in the modeling environment and to change the input and output signals of the bypass model without ECU code modifications. The RTI Bypass Blockset provides a generic user interface for this purpose, with the same look and feel no matter what ECU interface is actually used for bypassing. The Blockset allows flexible selection of functions to be bypassed in the ECU code (bypass hooks) and variables to be transferred without changing the ECU code itself.

Key Benefits
The RTI Bypass Blockset lets you concentrate on designing bypass functions for ECUs. The blockset is based on the dSPACE Calibration and Bypassing Service, the dSPACE XCP Service, or a CAN Calibration Protocol (CCP) service located on your ECU. In connection with the DCI-GSI1, the RTI Bypass Blockset can also be used without a service implementation. The blockset allows you to configure the bypass interface, as well as model inputs and outputs, flexibly without ECU code modifications. In addition, XCP on CAN, XCP on Ethernet (UDP/IP)1) and CCP service implementations from other vendors are supported.

Import of ASAM-MCD 2MC Files
An ASAM-MCD 2MC (ASAP2) variable description file can be easily imported as a database. An intuitive variable browser facilitates the handling of large description files by search options and hierarchical representation of variables. The variable names are mapped to the respective addresses on the ECU. The blockset allows you to access ECU variables via their names and automatically performs conversion between ECU hex and the physical representation on the dSPACE system.

Integration of Variable Editor
The Variable Editor can be integrated in the RTI Bypass Blockset:

• Create new or modify existing variables
• Create new or edit existing A2L files
• Export and import selected variables for easy exchange between models

¹⁾ As of December 2007, the XCP on Ethernet (UDP/IP) support is still under development and therefore subject to change. dSPACE reserves the right to alter the specifications at any time without notice.
