The SUSAN simulation solution consists of 4 complementary modules that form the entire functional ecosystem
Main part of this ecosystem is SUSAN advanced, that represents the computation module on which all simulations occurs. SUSAN connect is ethernet switch that enables an interconnection of devices via standard Ethernet and automotive Ethernet ports. Cryptographic module serves as secure key storage for ECU secrets and has a processor for calculating cryptographic signatures. SUSAN CAN extender must be used for more complex simulations where more than 2 CANs are required.
There are three different User Interfaces (HMI) implemented for operating with SUSAN
The phyHMI enables the system to be configured without additional end devices.
The remoteHMI provides an interface between external automation systems and SUSAN advanced via ethernet. It also allows to implement more complex custom simulations.
The webHMI is an interactive browser interface for the user to control the SUSAN system. It provides even more settings than the phyHMI due to the lack of its physical limitations while in the
same time being much more user friendly for complex configuration tasks like creating preset config files, etc.
The most available Use Cases are oriented for E3 1.2 PPE/PPC platform
Use Cases for MQBevo and MEB platforms are currently mainly oriented to One Infotainment Development. Available simulations for PPE/PPC are continuously being adoped into MQBevo and MEB platforms
SUSAN advanced is the main simulation system with with interfaces to automotive bus systems within VW Group. It consist of a Raspberry Pi compute module running the SUSAN Software Stack on top of a modified Linux distribution that presents the runtime environment for the simulated ECU functions. SUSAN advanced allows to simulation of vehicle functions of several electronic control units (ECU) on a single simulation system.

Cryptographic module is based on WIBU Systems CodeMeter Stick and provides a secure solution to store secret data of virtual vehicles. It enables the calculation and validation of cryptographic signatures, too. This is necessary for the calculation of message signatures. A single cryptographic module represents a virtual vehicle.
CodeMeter Sticks have been on the market as license dongle for years and are used successfully by numerous companies. The application has proven itself.
In order to use simulations that depend on more than two CAN interfaces, SUSAN advanced has to be expanded by more CAN interfaces provided by PCAN-USB adapter to ensure proper interconnection with all parts in test setup and expected functionality.
Currently SUSAN advanced supports two versions of PCAN-USB adapter
Both mentioned PCAN-USB adapters are supplied by Digiteq Automotive in a pre-configured state to ensure that they are seamlessly recognised.
