OptoLyzer® CAN FD Tool Solution Now Available from K2L

New Solution from K2L Combines OptoLyzer MOCCA FD Hardware Interface with OptoLyzer Studio Software to Create Integrated Development Solution


New to K2L’s product line of automotive bus interfaces, the OptoLyzer MOCCA Family, the OptoLyzer® CAN FD tool solution combines the OptoLyzer MOCCA FD hardware interface with the feature-rich OptoLyzer Studio software. Reaching from the OptoLyzer MOCCA CL that provides CAN and LIN support to the OptoLyzer MOCCA compact devices that add on top FlexRay and MOST® capabilities, the OptoLyzer MOCCA Family offers tailor-made solutions that can be applied to different phases of the automotive and engine control unit (ECU) development cycle. It is designed to aid in all stages of development including prototyping, simulation, implementation, analysis and verification. These offerings from K2L help reduce complexity, cost and time for designers, testers and system integrators.

The OptoLyzer MOCCA FD and OptoLyzer Studio Software are designed to work for CAN FD, CAN and LIN network development. The OptoLyzer MOCCA FD is a high-performance automotive bus interface. It offers two interfaces that can be configured either as CAN FD, high-speed CAN or single- wire CAN, four high-speed CAN interfaces and six LIN interfaces. K2L’s hardware component employs the Microchip MCP2561/2FD CAN FD transceiver. 4 kB sending and receive buffers ensure trouble-free communication even for heavy bus loads. The typical accuracy of CAN time stamps is 500 µs as the time stamping is also realized in the FPGA, it is extremely accurate. For the arbitration phase baud rates are supported from 40 kbit/s to 1 Mbit/s. Data phase baud rates reach from 40 kbit to 5 Mbit/s.

The accuracy of LIN time stamps is 1 µs. The system supports maximum transmission speed of 20 kbit/s (in total). LIN master, slave and spy functionality is supported. OptoLyzer MOCCA compact is able to transition from sleep mode to wake-up mode via the LIN bus.

For MOST25 implementations, the INIC’s clock mode can be changed to support 44.1 kHz or 48 kHz networks. For MOST50 and MOST150 implementations, the default of 48 kHz is supported. The integrated SpyNIC®, INIC and StressNIC chips ensure the feature set of OptoLyzer MOCCA compact. The accuracy of MOST time stamps is 500 µs. For optical MOST networks, the emitted light power on the FOT can be switched between 0 dB and -3 dB at runtime by software. The ring can also be interrupted by disabling the optical transmitter.

The accuracy of FlexRay time stamps is 500 µs. The termination depends on the bus topology. OptoLyzer MOCCA compact can be installed in various topologies, therefore a termination in the device is not implemented. The system does not run as bus guardian. OptoLyzer MOCCA compact provides one FlexRay bus with two channels. The bus is capable of transmitting up to 10 MBit/s (in total) according to the “Electrical Physical Layer Specification Version 2.0”. OptoLyzer MOCCA compact is able to transition from sleep mode to wake-up mode via the FlexRay bus.

The accuracy of Ethernet time stamps is 500 µs. OptoLyzer MOCCA compact supports Auto-MDIX, which allows the LAN interface to be connected via straight and crossed patch cables. A 10BASE-T and 100BASE-TX physical layer is also supported.

High-speed CAN buses complying with ISO11898-2 are terminated with 120 O at each end. Therefore, OptoLyzer MOCCA compact does not terminate the bus. The transmission speed range is from 40 kbit/s to 1 Mbit/s.

Fault tolerant CAN buses usually have a distributed termination. The value of the termination in each node depends on the number of nodes in the network. To avoid effects on the total impendence of the network, OptoLyzer MOCCA compact has a weak termination of 5.6 kO. Communication over the fault tolerant transceivers has an upper limit of 125 kbit/s.

OptoLyzer MOCCA compact can put all supported buses in sleep mode and transition from sleep mode to wake-up mode via a CAN interface.

Together with various PC software solutions including K2L’s new OptoLyzer Studio, the OptoLyzer MOCCA Family devices are of indispensable help during the entire development process. OptoLyzer MOCCA Family devices can easily connected to a PC via high speed USB 2.0. For customized applications of the hardware interfaces, a corresponding API is available.

The OptoLyzer Studio software includes a feature-rich graphical user interface that can be used to easily access the OptoLyzer MOCCA FD hardware. The OptoLyzer Studio is an easy-to-use software tool that allows device configurations, like baud rates and bit timing, to be changed easily. In addition, the trace view neatly displays the traffic on the attached buses and the behavior of signals can be observed in a graph view during online measurements.
