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
UDS diagnostic host computer (see KopherUDS diagnostic host computer for details):

KopherUDS (burning/diagnosis/repair)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.

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 Vector / ETAS tools?
Can.All KopherBit tools output standard AUTOSAR ARXML / DBC / OEM format files.Customers can import the KopherBit tool within existing Vector CANoe / ETAS INCA processes, or reverse the Vector / ETAS configuration to integrate with KopherSAR.
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?
Usually start with KopherConfig + KopherSAR, because these two are the core of BSW and ECU configuration; then gradually introduce Kopher SWC / Network Designer (application layer and communication matrix), KopherBoot (Bootloader), KopherUDS (diagnostic host computer).
