KopherBit AUTOSAR Tool chain overview: from SWC design to ECU mass production

Summary

The KopherBit AUTOSAR Classic toolchain connects application-layer modeling, communication matrices, BSW configuration, ECU-side diagnostics, and bootloader integration. Kopher SWC Designer models application SWCs, Kopher Network Designer manages communication matrices, KopherConfig generates configuration artifacts, KopherSAR provides the AUTOSAR Classic foundation, KopherBoot supplies the UDS bootloader, and KopherUDS implements diagnostic services inside the ECU. KITE UDS Tester and KITE Reflasher provide external validation and programming workflows.

Toolchain components

Kopher SWC Designer

Application layer Software Component (SWC) modeling tool that supports:

• Graphical modeling of Port, Interface, and Data Element.
• ARXML import/export (integrated with KopherConfig).
• Behavior description (Runnable, Implicit / Explicit Communication).

Kopher Network Designer

Communication matrix design tools:

• Create CAN / CAN FD / LIN / Ethernet matrix from the vehicle signal list.
• Export DBC, AUTOSAR System Description ARXML.
• Integrate with KopherConfig as BSW configuration input.

KopherConfig

ECU configuration authoritative source (see KopherConfig configuration tool for details):

• Generate Communication ARXML, AUTOSAR Platform ARXML, and Service Components ARXML from DBC import.
• Configure KopherSAR BSW modules (CanIf, PduR, COM, DCM, DEM, NM, Csm, etc.).
• Generate BSW code with one click.

KopherSAR

AUTOSAR Classic BSW (see KopherSAR AUTOSAR Classic BSW for details):

• Complete support for communication stack, diagnostic stack, I/O abstraction, memory management, Crypto Service, and RTE.
• Supports NXP MPC5744P and Infineon TC387QP.

KopherBoot

Vehicle specification UDS Bootloader (see KopherBoot UDS Bootloader for details):

• ISO 14229 complete set of Programming Session services.
• CAN / CAN FD / DoIP programming channel.
• HSM integration (TC387QP) completes Secure Boot.

KopherUDS

ECU-side UDS diagnostic middleware (see KopherUDS technical overview for details):

• Configure DID, DTC, sessions, SecurityAccess, and RoutineControl for the target ECU.
• Connect CAN / CAN FD / DoIP transport with ECU application callbacks.
• Validate responses, NRC behavior, diagnostic data, and regression cases with KITE UDS Tester.

Key Capabilities

• Single Vendor Integration: All tools and KCU hardware are from the same team and have the same interface.
• ARXML Standardization: The output of each tool is standard AUTOSAR ARXML, which can coexist with other AUTOSAR tools.
• Tightly integrated with KCU hardware: BSW default configuration, Bootloader section correspondence, diagnostic process consistency.
• Reuse across product lines: KCU GEN1 / GEN2 / GEN2 Micro / BCM / EVCC / EDR share the same set of tools and workflows.
• Support OEM customization: Each tool provides a customized interface that can be integrated into OEM’s own processes.

Engineering Inputs Required

Input	Purpose
Vehicle signal matrix	Kopher Network Designer input.
Application layer requirements and architecture	Kopher SWC Designer input.
ECU correspondence table (node ​​vs. ECU)	KopherConfig configuration basis.
Diagnostic requirements (DTC, DID, SecurityAccess)	DCM/DEM configuration and KopherUDS operation process.
Bootloader signature strategy	KopherBoot signature verification, HSM integration.
Vehicle network topology	Confirm transport layer (CAN / CAN FD / Ethernet).

How KopherBit Supports This

• Full Toolchain Licensing: Can be licensed individually or provided as a complete set.
• Service support: KCU platform introduction consultant, ECU configuration consultation, ASIL/information security planning.
• Training: AUTOSAR Classic, UDS, ISO 15118 PnC, Secure Boot and other theme courses.
• Verification: KCU Platform Testbench provides integration testing.

FAQ

Does the KopherBit toolchain have to be used with KCU hardware?

uncertain.The tool chain itself can be independently licensed, producing standard ARXML and BSW code that can be ported to customers’ own ECU platforms (requires compatibility with NXP MPC5744P / Infineon TC387QP or customized MCAL porting).However, KCU hardware + KopherBit tool chain can be used together to obtain the fastest online time and the best integration experience.

Can it coexist with an existing engineering toolchain?

Yes. KopherBit tools exchange AUTOSAR ARXML, DBC, ODX, and project-defined OEM artifacts with existing workflows. Teams can introduce modeling, configuration, diagnostics, or validation capabilities incrementally without replacing the entire environment at once.

Which MCU platforms does the tool chain support?

Mainly supports NXP MPC5744P (KCU GEN1) and Infineon TC387QP (KCU GEN2 / GEN2 Micro).MCAL can be transplanted to other automotive MCUs (S32K3, TC397, TC4xx, etc.) according to project requirements.

Is Adaptive AUTOSAR in the toolchain?

The current tool chain is mainly AUTOSAR Classic.Adaptive scenarios can communicate with Classic ECU through SOME/IP, and KopherBit can help design Classic-Adaptive hybrid architecture.

How do I choose which tool to start importing from?

Teams usually start with KopherConfig + KopherSAR as the BSW and ECU configuration foundation, then add Kopher SWC / Network Designer, KopherBoot, ECU-side KopherUDS, and external validation or programming tools as the project requires.
