We provide proven IP cores for a variety of IOs and buses, including DisplayPort, Ethernet MAC and networking stacks, SDLC & HDLC Data Link Controllers, I2C/SMBUS, LIN, SPI, PCI, and PCI Express.
Our interconnects IP line features the first available soft or firm core for the CAN Flexible Data specification: the CAN-CTRL CAN 2.0 & CAN FD Bus Controller Core.
Sourced from Fraunhofer IPMS, this second-generation CAN Bus Controller adds FD support to the CAN 2.0 controller core CAST has carried for several years. The core’s FD extension completely supports the CAN with Flexible Data-Rate Specification released by Bosch in April 2012. This improved data link layer protocol significantly increases bandwidth, making the CAN bus suitable for the greater demands of modern automotive, industrial control, and other systems. As provisioned by the spec, the new core imposes no changes on the physical layer, allowing the gradual updating of existing CAN networks with CAN FD capacities.
“CAN FD makes the stability and reliability benefits of the CAN bus available to designers of today’s more data-hungry systems, and we’re excited to be the first delivering this capability in an easy to use and integrate soft core via our partnership with Fraunhofer,” said Nikos Zervas, chief exective officer for CAST. “The flexibility and performance of this royalty-free CAN controller core have already helped some fifty customers get to market on time and on budget, and we expect this FD option to help many more.”
The CAN Controller 2.0/FD IP core is available in VHDL or Verilog source code, or FPGA netlists. Deliverables include scripts and a testbench for verification.
