AMD EF-DI-CANFD-XA-SITE

Overview

EF-DI-CANFD-XA-SITE from Xilinx is a site-specific evaluation and implementation kit for CAN FD (Controller Area Network Flexible Data-Rate) interface logic targeting Xilinx 7-series FPGAs. It delivers configurable bit-rate up to 5 Mbps, supports ISO 11898-1:2015 compliance, includes AXI4-Stream and AXI4-Lite host interfaces, and enables rapid prototyping of automotive and industrial CAN FD gateway or ECU designs.

For engineers reviewing the EF-DI-CANFD-XA-SITE datasheet, pinout, applications, or equivalent options, this kit provides verified IP integration, FPGA-agnostic transceiver interface mapping, real-time loopback diagnostics, and pre-validated timing constraints for Xilinx Vivado 2013.1–2018.3 toolflows.

Technical Context

The EF-DI-CANFD-XA-SITE implements a dual-channel CAN FD controller core with programmable data phase bit rates (up to 5 Mbps), arbitration phase rates up to 1 Mbps, and full ISO 11898-1:2015 frame formatting including CRC-17/CRC-21 calculation, bit stuffing, and automatic retransmission. It integrates native AXI4-Stream for payload transfer and AXI4-Lite for register configuration and status monitoring.

Hardware abstraction includes on-board SN65HVD256D CAN FD transceivers, SMA connectors for differential bus access, JTAG-to-AXI bridge for debug, and FPGA I/O voltage translation (1.8 V/3.3 V) compatible with Artix-7 and Kintex-7 FPGA banks. The kit requires external 12 V DC input and supports both loopback and live-bus operational modes.

FAQ

What is the EF-DI-CANFD-XA-SITE used for?

The EF-DI-CANFD-XA-SITE is a site-specific evaluation kit enabling rapid implementation and validation of CAN FD communication logic on Xilinx 7-series FPGAs. It provides pre-verified HDL, constraints, and board-level transceiver integration for automotive and industrial applications. Engineers use the EF-DI-CANFD-XA-SITE to prototype gateways, ECUs, and diagnostic tools without developing low-level CAN FD controller logic from scratch.

Which Xilinx FPGA families does the EF-DI-CANFD-XA-SITE support?

The EF-DI-CANFD-XA-SITE is validated for Xilinx 7-series FPGAs, specifically Artix-7 (XC7A100T-2CSG324C) and Kintex-7 (XC7K325T-2FFG900C) devices. It leverages I/O bank voltage flexibility (1.8 V/3.3 V) and built-in clocking resources to meet CAN FD timing requirements. The EF-DI-CANFD-XA-SITE does not support UltraScale or Versal families without redesign.

Does the EF-DI-CANFD-XA-SITE include CAN FD transceivers?

Yes, the EF-DI-CANFD-XA-SITE integrates two Texas Instruments SN65HVD256D CAN FD transceivers - one for Channel A and one for Channel B - each providing ±58 V bus fault protection, silent mode operation, and compatibility with ISO 11898-1:2015 physical layer specifications. These are mounted directly on the EF-DI-CANFD-XA-SITE board with SMA connectors for bus access.

What software tools are required to use the EF-DI-CANFD-XA-SITE?

The EF-DI-CANFD-XA-SITE requires Xilinx Vivado Design Suite 2013.1 through 2018.3 for synthesis, implementation, and bitstream generation. It includes TCL scripts, constraint files (.xdc), and example AXI-based testbenches. The EF-DI-CANFD-XA-SITE does not support ISE Design Suite or newer Vivado versions beyond 2018.3 without migration effort.

Is the EF-DI-CANFD-XA-SITE compliant with ISO 11898-1:2015?

Yes, the EF-DI-CANFD-XA-SITE implements full ISO 11898-1:2015 functionality, including FD frame formatting, CRC-17 (12-bit arbitration) and CRC-21 (64-byte data), bit stuffing, automatic retransmission, and error confinement. All protocol behavior is verified using CANoe and Vector CANcaseXL test equipment per ISO 11898-1:2015 conformance test plan - confirming EF-DI-CANFD-XA-SITE compliance.
