C³: configurable CAN FD controller: design, implementation and evaluation

Afşin, Mehmet Ertuğ
CAN FD (Controller Area Network with Flexible Data Rate) is a new communication standard, compatible with CAN. Different from CAN, CAN FD switches to high data rate during data transmission and allows payloads up to 64 bytes. In this thesis, we propose C3: Configurable CAN FD Controller which features up to fully configurable 96 TX and 96 RX buffers organized as mailboxes. Each RX buffer has dedicated acceptance filters. The host MCU sees C3 as a memory mapped device and interfaces with it via SPI protocol which is designed and developed in the scope of this thesis. Different from existing CAN FD Controllers, C3 provides run time configurable number of buffers and individual buffer sizes which makes it best use of a single hardware for every application. Furthermore, it provides efficient and flexible usage of a limited embedded memory. C3 is implemented on a Xilinx Virtex 5 FPGA demo board as an IP Core and its functions are verified at 2Mbps and the response time measurements are performed to evaluate the timing performance.


Development of strategies for reducing the worst-case message response times on the Controller Area Network
Çelik, Vakkas; Schmidt, Şenan Ece; Schmidt, Klaus Verner; Department of Electrical and Electronics Engineering (2012)
The controller area network (CAN) is the de-facto standard for in-vehicle communication. The growth of time-critical applications in modern cars leads to a considerable increase in the message tra c on CAN. Hence, it is essential to determine e cient message schedules on CAN that guarantee that all communicated messages meet their timing constraints. The aim of this thesis is to develop o set scheduling strategies that find feasible schedules for higher bus load levels compared to conventional CAN scheduling...
A Frame packing method to improve the schedulability on CAN and CAN-FD /
Urul, Gökhan; Schmidt, Şenan Ece; Schmidt, Klaus Verner; Department of Electrical and Electronics Engineering (2015)
Controller Area Network (CAN) is the most widely used in-vehicle network. Today, vehicle applications can fill a CAN network's communication bandwidth to its limit. Hereby, the consumed bandwidth of an in-vehicle application depends on the efficiency of packing signal data into CAN message frames and on the suitability of the CAN message priority assignment such that all messages are schedulable. This thesis focuses on the problem of signal packing which is known to be and NP-hard problem. To this end, the ...
C3: Configurable CAN FD controller: Architecture, design and hardware implementation
Afşin, Mehmet Ertuǧ; Schmidt, Klaus Verner; Schmidt, Şenan Ece (2017-07-26)
CAN FD (Controller Area Network with Flexible Data Rate) is a new standard which provides a fast data rate while preserving the compatibility with CAN. In this paper, we propose the C 3 (Configurable CAN FD Controller) IP core architecture, which is compatible with the non-ISO CAN FD standard. C 3 supports up to 96 transmit and receive buffers. The transmit buffers are organized as mailboxes with CAN ID prioritization in frame transmission. A separate filter mask that can be configured by the user exists fo...
Controller area network with offset scheduling: improved offset assignment algorithms and computation of response time distributions
Batur, Ahmet; Schmidt, Klaus Werner; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2018)
The Controller Area Network (CAN) is the most widely-used in-vehicle communication bus in the automotive industry. CAN enables the exchange of data among different electronic control units (ECUs) of a vehicle via messages. The basic requirement for the design of CAN is to guarantee that the worst-case response time (WCRT) of each message is smaller than its specified deadline. Hereby, it is generally desired to achieve small WCRTs that leave sufficient slack to the message deadline. In addition, it has to b...
A comparative study of evolutionary network design
Kalkan, Sinan; Şehitoğlu, Onur Tolga; Üçoluk, Göktürk; Department of Computer Engineering (2003)
In network design, a communication network is optimized for a given set of parameters like cost, reliability and delay. This study analyzes network design problem using Genetic Algorithms in detail and makes comparison of different approaches and representations. Encoding of a problem is one of the most crucial design choices in Genetic Algorithms. For network design problem, this study compares adjacency matrix representation with list of edges representation. Also, another problem is defining a fair fitne...
