Step 1 (MIL): Early model development phase in MATLAB/Simulink

� In the context of model-based software development

� Functions of the application are tested in an iterative process

� The model is executed iteratively in Simulink

� Initial parameter calibration is necessary

Use CANape During The Entire Development Process

CANape Option “Simulink XCP Server”

6

Step 1 (MIL): Early model development phase in MATLAB/Simulink

� With the CANape Option “Simulink XCP Server”

� CANape can be used as a familiar GUI for the models running in Simulink

� Access to the model running in Simulink via XCP

� CANape projects/configuration can be reused in a later development phase

Solution


Advantages:

� Algorithms can be optimized in an early development phase

� No hardware is available

� Full access to all signals/parameters

� Use of measurement/calibration window

� All CANape features (e.g. measurement analysis, calibration data management, …) can be used

� Better usability than in MATLAB/Simulink

� Use of captured real data in Simulink

� Working with standards

How to use the Simulink XCP Server:

� Only one block must be added

� Configure Simulink XCP Server

� Automatic file generation

� A2l � Model explorer � CANape project

� Start CANape project within Simulink

� Simulink model behave like virtual ECU

Step 2 (SIL): First Rapid Prototyping

� Initial development of model is finished

� Model testing with real data (online/offline) in real time

� The model is executed on the PC (DLL)

� Parameter calibration with real ECU environment

Setup


� With the CANape/vSignalyzer Target, the model is compiled into a DLL and can be used in real time with real data

� Add DLL to any CANape project and connect the ports to real data (CAN, CCP/XCP, I/O …, even signals from measurement files) inside CANape

15

Solution


Advantages:

� Model/algorithm can run with real data (online/offline)

� CANape acts as interface to real data

� No HW and no MATLAB necessary

� Model can be used by multiple engineers

� The model itself can be measured and calibrated (like an ECU)

� No rebuild of the model necessary

� All CANape features can be used

� Working with standards

How to use CANape/vSignalyzer Target:

� Add CANape input/output blocks to the ports of your model

� Configure the CANape Target

� Generate code/DLL

� Add the DLL to CANape and connect the ports to real data

Optional:

� Create a device with the generated Simulink DLL & A2L

� Measure and calibrate the DLL

Bypassing, Fullpassing

Step 3: SIL, HIL and target platform

� Model testing on real time hardware and target ECU

� Fast modification of ECU algorithm, without complete ECU SW generation/flashing

� HIL on test benches or real car verification

� Final parameter calibration and variant parametrization

� DLL execution on real time hardware VN8900

� Configuration in CANape execution on external hardware

� CANape/vSignalyzer Target DLL as bypass/fullpass solution

� Reuse of CANape project/configurations

� One calibration tool from step 1 to step 3

� Same configuration for final validation in cars and first model development

18

� Fast modification of ECU algorithm or code segments without

� Complete ECU SW generation

� Flash programming

� The existing ECU hardware has insufficient RAM, flash ROM or CPU speed

� Possibility to test the new application

� Switch between original ECU application and the new algorithm

� Compare both under real conditions

Motivation for Bypassing


19

� Bypass execution on the PC or on the real-time VN8900 hardware

� High-end ECU access with our VX1000 solution

� High amount of signals or increased sample rates

� Time synchronous write and read

� All signal sources in CANape can be used as additional inputs/outputs

Advantages:

� Vector real-time bypassing platform

� No/small jitter and latency times

� Support of “Extended Real Time” on VN8911 or VN8912A

� Bypass can also be measured and calibrated if it runs on the VN8900

� Bypass can run standalone on VN8900

22

� The complete ECU software runs on VN8900 as model

� The models receive data from > CAN, LIN, FlexRay

> ECUs (VX1000) – only ECU I/O´s

� Models can be executed on VN8900 stand-alone

� Optional:

� The model internals can be measured/calibrated by CANape
