Co-Simulation with TPT/FUSION

Co-simulation tests
in TPT's FUSION environment
The integration platform FUSION by PikeTec makes it
possible to connect an arbitrary number of software
modules, that practically need different execution
environments, as a single closed system. The modules
can exchange data during the test run. The FUSION
platform supports many test environments like C-code,
CAN, INCA, PLS UDE, ASCET, MATLAB Simulink, Functional
Mockup Units (FMUs), and external I-O-cards.

FUSION nodes.
The modules connected to the FUSION are called nodes.
Each node is connected to the FUSION via an API. Each
node reads input signals, calculates its outputs for a
time step and writes them to the FUSION. The nodes are
executed per sample one after the other in their order.
More complex scheduling and function calls are
possible.
FUSION nodes can exchange signals with each other and
with TPT at any time.
If a real-time node is inserted, the test execution
takes place in real time, although FUSION as a Windows
process does not meet real real-time requirements. By
using the real-time node TPT can communicate with
external hardware, HiL systems or application tools.
You can also write FUSION nodes yourself. For this
purpose, you will find your own API, which can be used
to configure initializations and cyclic interactions
between TPT and your system. How this works in detail
is described in the FUSION Programmers Guide.
You can generate FUSION nodes from MATLAB Simulink/Targetlink
models, ASCET models, or AUTOSAR software components
automatically at the push of a button with TPT. You can
simulate these nodes with other nodes in a completely
flexible way. This makes rapid SiL tests possible.
