CAN 2.0, CAN FD, and CAN XL Bus Controller - Developed as ISO26262-10 Safety Element out of Context (ISO26262 soft IP SEooC, ASIL-B ready design)
DCAN FD bridge to APB, AHB, AXI bus, it is a standalone controller for the Controller Area Network (CAN), widely used in automotive and industrial applications. The DCAN FD was designed in accordance with ISO 11898-1:2015 and conforms to:
Bosch CAN 2.0B specification (2.0B Active) and
CAN FD (flexible data-rate).
Sophisticated error detection functions (which increase communication reliability) and unique fault confinement (which guarantees network-wide data consistency) has decided about CAN’s popularity. Because of its fundamental role in all aspects of security and safety, trustworthy implementations are crucial. That’s why DCD-SEMI developed a unique IP Core, which delimits the highest quality standards. The improved protocol overcomes standard CAN limits: data can be transmitted faster than with 1 Mbit/s and the payload (data field) is up to 64 bytes long and limited to 8 bytes anymore. When only one node is transmitting, the bit rate can be increased, because no nodes need to be synchronized. Of course, before the transmission of the ACK slot bit, the nodes need to be re-synchronized. The core has a simple CPU interface (8/16/32 bit configurable data width), with a small or big-endian addressing scheme. Hardware message filtering (32 filters) and 128 bytes receive FIFO enable back-to-back message reception, with minimum CPU load. The DCAN FD is provided as HDL source code, allowing target use in FPGA and ASIC technologies.
The IP core is available in two versions – Basic and Safety-Enhanced.
This sophisticated solution’s been developed as ISO26262-10 Safety Element out of Context. It can optionally be improved by necessary safety mechanisms and provide detailed safety documentation: all ISO26262 soft IP SEooC required work products, which include complete Failure Modes Effects and Detection Analysis FMEDA analysis with step by step instruction to help to integrate the IP into the customer’s system and to conduct the system-level safety analysis. All the safety-related work products were checked by a third-party, independent audit.
The conducted safety analysis depicts, that the safety metrics are fulfilled and both IPs reach the Automotive Safety Integrity Level ASIL-B (Single Point Fault Metric SPFM > 90%, Latent Fault Metric LFM > 60%). DCD-SEMI delivers a complete FMEDA analysis with step-by-step instruction to help to integrate the IP into the customer’s system and to conduct the system-level safety analysis.
This ASIL-B ready design may easily be used in Automotive Safety Systems at the ASIL-B level, but DCD-SEMI may optionally deliver higher ASIL level ready IP. For further information and the optional features please contact our support.
