Demos

This chapter describes the demo projects of the SIL Kit.

The demos are organized into three categories:

1. Communication Protocols

These demos showcase multi-participant systems for communication via Can, Ethernet, Lin, Flexray, PubSub or Rpc:

Can: The CanWriter participant sends Can frames to the CanReader participant including frame acknowledgment handling.
Ethernet: The EthernetWriter participant sends Ethernet frames to the EthernetReader participant including frame acknowledgment handling.
Lin: A two-node Lin Setup with a LinMaster and a LinSlave. Includes a simple scheduling mechanism and demonstrates controller sleep / wakeup handling.
FlexRay: A two-node FlexRay Setup with a full cluster and node parametrization. Includes POC Status handling, buffer updates and reconfiguration. This Demo requires a separate Network Simulator application to simulate the details of the FlexRay cluster, which is not included in the SIL Kit.
Publish/Subscribe: One participant publishes GPS and temperature data, another participant subscribes to these topics. Including (de-)serialization of the C++ structures into a transmittable format.
Rpc: The Rpc server participant provides two simple functions which are called by a Rpc client participant. Includes (de-)serialization of the function parameters.

2. API

These demos focus on a basic systems and single topic of the SIL Kit API:

Simple Can: Minimalistic demo for a participant with Can communication and virtual time synchronization.
Autonomous lifecycle: Minimal example of a participant with an autonomous lifecycle. The demo shows that this participant can be started and stopped independently from other participants.
Coordinated lifecycle: Minimal example of a participant with a coordinated lifecycle. This shows how multiple participants can be started and stopped simultaneously, controlled by the sil-kit-system-controller.
Simulation step handler: Minimal example of a participant with time synchronization and a simulation step handler.
Asynchronous simulation step handler: Minimal example of a participant with time synchronization and an asynchronous simulation step handler.
Network Simulator API: Demonstrates the usage of the experimental SIL Kit NetworkSimulator API. A custom network simulation for Can is set up, the network simulator application can be used together with the Can demo.

3. Tools

Tools for performance analysis:

Benchmark Demo: This demo sets up a simulation with various command line arguments for benchmarking purposes. A configurable amount of participants are spawned by a single process on different threads. The demo calculates averaged running times, throughput, speed-up and message rates for performance evaluation.
Latency Demo: A sender and a receiver application use the Publish/Subscribe services and measure the round trip time of the communication. This setup is useful to evaluate the performance of a SIL Kit setup running on different platforms. E.g., between a local host, a virtual machine, a remote network, etc.
