Simulink® blockset providing ECU read and write access from dSPACE real-time platforms via different kinds of ECU interfaces such as CCP, XCP, DPMEM PODs or on-chip debug ports. The blockset is especially designed for the dialog-based configuration of bypass applications. It allows ASAM MCD-2 MC (ASAP2) files to be imported and ECU variables to be selected via a convenient browser. It handles conversion formulas and the selection of bypass hooks automatically. In addition, the RTI Bypass Blockset supports on-target (internal) bypassing, allowing the bypass model to be compiled and downloaded directly into the free flash memory and RAM of the target ECU. For this, model parameters and signals are automatically added to the ECU’s ASAM MCD-2 MC (ASAP2) file.
