DCAN FD

DCAN FD IP Core — High-Performance, ISO11898-1:2015-Compliant CAN FD Solution for Automotive & Industrial Designs

The DCAN FD IP Core from DCD-SEMI delivers a powerful, flexible, and scalable solution for integrating Controller Area Network (CAN) communication into modern embedded systems. Designed for seamless implementation in ASIC, SoC, or FPGA architectures, this advanced controller fully complies with the ISO11898-1:2015 standard, ensuring reliable operation with industry-proven CAN protocols.

Supporting both Classical CAN and CAN FD, the DCAN FD IP Core enables high-bandwidth, low-latency communication while maintaining full backward compatibility. Physical connection to the CAN bus is achieved using external transceiver hardware, allowing developers to tailor their system design to specific application requirements.

Efficient Architecture with Flexible Message Handling

A dedicated 32-bit Generic Interface ensures straightforward integration with the host CPU, accelerating system design and guaranteeing fast, dependable data exchange.

Available in Basic and Safety-Enhanced Versions

To support a wide range of applications, the DCAN FD IP Core is offered in two variants:

• Basic Version – ideal for standard CAN FD implementations

• Safety-Enhanced Version – developed as an ISO 26262-10 Safety Element out of Context (SEooC)

The Safety-Enhanced version includes comprehensive functional safety support, such as:

• Full FMEDA (Failure Modes, Effects and Diagnostic Analysis)

• Integration guidelines for system-level safety analysis

• Complete ISO 26262 documentation set

• Optional additional safety mechanisms

All safety documentation has been validated through third-party independent audit, ensuring full compliance and maximum trustworthiness.

ASIL-B Ready Functional Safety — Extensible Toward ASIL-D

The completed safety analysis confirms that the DCAN FD FULL IP Core meets all ASIL-B functional safety requirements, achieving the following key metrics:

• SPFM > 90% (Single Point Fault Metric)

• LFM > 60% (Latent Fault Metric)

These results validate the suitability of the DCAN FD FULL for integration into automotive systems targeting ASIL-B safety goals.
Additionally, DCD-SEMI can provide enhanced variants tailored to support architectures requiring higher safety integrity levels — including ASIL-D — to meet specific OEM or Tier-1 requirements.
