IG lower layers

Scope

The Interest Group (IG) lower layers, preceeding IG lower layers, is responsible for all CAN lower layers specifications. The IG develops additional specifications, recommendations and implementation guidelines for CAN FD. This covers CAN FD physical layer recommendations with special regard to topology and bit timing, recommendations with regard to system design as well as with regard to CAN FD controller interfaces, additional requirements for HS-PMA implementations compliant with ISO 11898-1: 2015 and ISO 11898-2:2016 with the signal improvement capability (SIC), requirements and test methods of the mechanical and electrical parameters for cables to be used in CAN FD networks and for common-mode chokes to be used in Classical CAN networks and CAN FD networks. Furthermore, the IG devolops specifications and test plans for CAN XL. It is intended to cover data link layer and physical signaling, physical media attachment sub-layer, node and sytem design recommendations, and etc.

CiA 601-1 version 2.0.0CAN FD Node and system design – Part 1: Physical interface implementation
DescriptionThis set of documents specifies and recommends the usage of CAN FD hardware implementations. It consists of the following parts: Part 1: Physical interface implementation, Part 2: Controller interface specification, Part 3: System design recommendation, Part 4: Ringing suppression. This part provides specifications and guidelines on the physical layer interface design for automotive electronic control units and non-automotive devices supporting the CAN FD data link layer as defined in ISO 11898-1 and the CAN high-speed physical layer as defined in the harmonized ISO 11898-2 standard, which includes the specification of high-speed transceivers with low-power mode (formerly known as ISO 11898-5) and/or with selective wake-up functionality (formerly known as ISO 11898-6).

CiA 601-2 version 1.0.0CAN FD Node and system design – Part 2: CAN controller interface specification
DescriptionThis set of documents specifies and recommends the usage of CAN FD hardware implementations. It consists of the following parts: Part 1: Physical interface implementation, Part 2: Controller interface specification, Part 3: System design recommendation, Part 4: Ringing suppression. This part describes the specified interface between the protocol controller implementing the CAN FD data link layer protocol and the host controller including necessary configuration registers. Such a harmonized interface reduces the effort for adapting the low-level driver software to different implementations.

CiA 601-4 version 2.0.0CAN FD Node and system design – Part 4: Signal improvement
DescriptionThis set of documents specifies and recommends the usage of CAN FD hardware implementations. It consists of the following parts: Part 1: Physical interface implementation, Part 2: Controller interface specification, Part 3: System design recommendation, Part 4: Signal improvement, Part 6: CAN FD cable. This document specifies additional requirements for HS-PMA implementations compliant with ISO 11898-1:2015 and ISO 11898-2:2016 for the purpose to reduce differential and common-mode ringing on the CAN_H and CAN_L wires, especially for the transition from dominant to recessive state. The intent of this specification is to enable larger topology flexibility and higher bit rates for CAN networks. The HS-PMA implementations with additional signal improvement functionalities support communication in the presence of defined unterminated wire stubs without requiring configuration, for example bit-rate settings. Furthermore, this document specifies EMC tests for HS-PMA implementations with additional signal improvement functionalities.

CiA 603 version 1.0.0CAN Frame time-stamping – Requirements for network time management
DescriptionThis documents specifies the time-stamping when transmitting or receiving Classical CAN or CAN FD data frames. This time-stamping can be used to introduce a synchronized time-base in a network segment, particularly in AUTOSAR systems. The synchronized time-base is suitable for but not limited to advanced driver assistance systems (ADAS), event data recording, and synchronizing actuations.
