Avionics SIL

Systems Integration Laboratory

The Systems Integration Laboratory (SIL) is an integrated ground test environment for the development of aviation
and electronic systems.

It is used as the most effective tool to verify the reliability of the functions and performance of all aviation and electronic systems.

It is the best solution to test while integrating actual equipment and LRU software models.

SIL is an integrated ground test environment for integrated testing of radar,
avionics, engines, and various armament that high-performance aircraft must have
in place in a similar environment and method to the actual flight situation.

In the process of integrating aircraft-mounted equipment into a single aircraft,
incongruity or frequent system collisions occur. In other words,
it plays a role in harmonizing almost all the hardware and software
that make up the aircraft, from the aircraft development stage to the final
completion and testing stage.

The accuracy and completeness of the SIL play a key role in reducing the risk of aircraft
development and shortening development costs and development periods

The SIL environment provides all integrated aviation and electronic equipment
interworking environments for functional and software verification of mission
equipment and helps analyze errors that occur during system integration.

In actual flight tests, virtual model implementation and fault injection,
convenient switching tests of simulation models and actual equipment, abnormal
mode detection, and various error analysis functions must be provided to enable
testing in extreme flight environments including abnormal modes that cannot be performed.
Real-time processing must be possible for high reliability of test data.

Therefore, SIL construction requires more manpower, time, and highly
accumulated experience than any other equipment development.

REALTIMEWAVE has developed an RTNgine solution optimized for building an SIL
environment through long experience in manufacturing a test environment.

We have launched a flexible and well-integrated test solution with a proven simulation
engine that complements model-based workflow.

It ensures data reliability under strong multi-core CPU and real-time OS
environments, supports most of the interfaces required by the latest technology,
and enables fast simulation in conjunction with a variety of model development
environments (Matlab/Simulink, C, Fortran, etc.). It also provides products
with a variety of functions, from deriving test needs
to managing large amounts of ICDs and accurate analysis and automation of test data.

Using REALTIMEWAVE’s SIL solution means that you don't spend a lot of time
building and setting up an SIL environment,
but only focus on actual tests. This already has a very
important factor in project success.

It's not about building an aircraft, it makes it possible to fly.
It is a complete solution for aircraft-level system integration testing in the laboratory.
