Wake-Up Pattern in CAN/CAN FD Networks

Revised Wake-Up Pattern

With the ISO11898-2: 2016 specification, the wake-up pattern for classic CAN and especially for CAN FD networks has been revised: The new wake-up Pattern is significantly more robust than its predecessor from ISO 11898-5: 2007.

Our short article compares the wake-up patterns of the two ISO documents and describes how to create an appropriate wake-up pattern.

Real-Time Solutions

Vector offers you solutions with deterministic time behavior for real-time critical applications, such as the simulation of complex networks or bypassing:

Network Simulation
CANoe	Conduct remaining bus simulations across networks and test ECUs and entire networks using a single tool that offers functions for analyzing and stimulating CAN, but also LIN, FlexRay and more.
CAPL-on-Board	This special run mode for CAPL network nodes enables time- and performance-critical simulation models to be run directly "on-board" on the network interface. Benefits: Less jitter / less timer delays Less PC utilization
High Performance Interfaces as RT Server: VN8900 Family and VT6000 Family	The VN8900 and VT6000 real-time systems consist of these 2 components: User PC: As front-end for operation of graphical user interface of CANoe As host for the logging of data and test results High performance interfaces: RT server as runtime environment: For the remaining bus simulation and environmental simulation For execution of test scripts Benefits: User interface and simulation part are isolated from each other. For this reason other PC tasks, such as compiling, virus checking, Outlook, etc., do not adversely affect the bus simulation and measurement. System configurations can be easily scaled based on user-defined requirements, e.g. monitoring, soft real-time simulation, real-time simulation. The same model can be run both in a real-time environment and in a conventional environment. The model can be run in the real-time environment with higher accuracy and lower jitter and is thus more deterministic. The workflow is the same as the standard CANoe workflow.
Bypassing
CANape	The primary application area of CANape is optimizing the parameter set (calibration) of ECUs. The communication between CANape and the ECUs takes place via protocols such as XCP or via microcontroller-specific interfaces with the VX1000 hardware. CANape and VX1000 for measuring, calibrating, and flashing via XCP with a high data throughput and minimum runtime influencing of the ECU.
