About Silver

Silver is a Software-in-the-Loop (SiL) solution to create and run virtual ECUs (vECUs). It provides an early, scalable, cost-effective, and deterministic simulation platform for ECU development, functional test, and validation.

Increasing software complexity further delays the availability of ECUs due to larger and time-consuming iteration cycles. Automotive manufacturers need to test their ECUs as early as possible, ideally before HW is available to meet aggressive Time-To-Market schedules and with that, reduce costs. Virtual ECUs are key to fast feedback loops and thus ensure the quality of complex control software.

Silver accelerates software development by enabling suppliers and manufacturers to integrate, test, and debug SW, ahead and independent of HW test rigs. Silver supports application integration, middleware integration, and operating system integration use cases (L1..L3 vECU layers). With that, Silver can isolate software modules, software layers and any combination of software modules in ECU software of any complexity, and enables vertical, horizontal and hybrid integration tests in the early stages of development. 

By supporting automotive standards like ASAM, AUTOSAR, FMI, CAN, Ethernet, etc. Silver seamlessly integrates into every ecosystem and test automation framework. To further increase the simulation fidelity with production code drivers, Silver can be coupled with Virtualizer – Synopsys’ solution for partial and full binary SW stack integration.

Key Benefits

Time & Cost Saving

Dissolve HW dependencies with a virtual copy of the real ECU

Efficient Development

One single tool for creating and running vECUs for multiple purposes

Powerful Execution

A versatile vECU runtime environment with a plethora of interoperability options

Features

<p>With Silver, you can build virtual ECUs that closely mimic the behavior of their real counterparts. Silver is also a powerful experimentation environment for validating and testing the interaction of networked ECUs, engine, transmission and other vehicle components through simulation.</p>

Powertrain Development Without Additional Hardware

With Silver, you can build virtual ECUs that closely mimic the behavior of their real counterparts. Silver is also a powerful experimentation environment for validating and testing the interaction of networked ECUs, engine, transmission and other vehicle components through simulation.

<p>Do not lose time anymore when upgrading to a new software release on the vehicle. After the initial effort to set-up the automated build process, updating the vECU for a new software release is typically done within a few minutes. This way, software bugs can be detected early by simulation, before moving to the vehicle.</p>

Saving Time and Costs with Continuous Integration

Do not lose time anymore when upgrading to a new software release on the vehicle. After the initial effort to set-up the automated build process, updating the vECU for a new software release is typically done within a few minutes. This way, software bugs can be detected early by simulation, before moving to the vehicle.

The Software Environment

Silver allows to run simulation models of various tools (such as MATLAB / Simulink, Dymola, SimulationX, MapleSim, AMEsim, GT-Power, axisuite) on your computer without having these tools installed in the execution environment. During distributed development, models are exchanged between developers in binary form (FMU, sFunction, Silver module) – without passing the corresponding source code. This helps to protect your know-how.

Under the Hood

Depending on the use case and the availability of source code, different parts of the ECU software can be ported to a PC: (A) only the Application Software (ASw) is virtualized, (B) also parts of the Basic Software (BSw). 

A Silver configuration can also be duplicated quickly. This allows every developer to use his or her personal development environment without blocking scarce resources such as HiLs, test rigs or test vehicles.

Virtualization

We virtualize your electronic control unit based on Silver, either once as part of a pilot project, or continuously during development for each software release.

We provide consulting on how to use virtual ECUs (vECUs) to optimize your development process (keywords “continuous integration,” “nightly build”) and help you with setting up of such a process, for example, based on Jenkins.

Benefits

  • Development and validation tasks move from road and hardware rigs to the workstation. Simulations can be done on an individual PC or in parallel on a network. 
  • Build a vECU from Simulink models, C-code, x86 objects or binaries 
  • Run your partial or full-blown production application software and basic software in a virtual prototype 
  • Compose a vECU out of multiple binaries to support supply chain workflow and IP protection 
  • Automated generation of AUTOSAR RTE and OS substitution code for faster virtual prototype bring up. 
  • Vendor-independent Silver MCAL Plugins for basic software configuration tools (e.g., Elektrobit tresos Studio) 
  • Protect your IP by exchanging binary simulation components with your supply chain
