Why use HIL simulation?
The main purpose with the HIL Simulation is to test the hardware d
on a simulator before we implement it on the real process.
Why not connect the embedded system under test
“real plant”, that is the dynamic system being contr
to perform development and testing?

The metric of development and test efficiency is typically a formul
includes the following factors:
Cost
DurationSafety
You may want to test the different part of the system individually to
sure it works as planned

Challenges
When testing, we have lots of challenges:
Cost to test
Cost of failure Availability
System variation
Repeatability
In these situations is HIL simulation a powerful technique.
With HIL Testing
• Cost and risk will be reduced• Increased reliability and quality
• More efficient development
• Lower cost to innovate

• It is also very useful for training purposes, i.e., the process opera
learn how the system works and operate by using the hardware-
loop simulation.
• Another benefit of Hardware-In-the-Loop is that testing can be do
without damaging equipment or endangering lives.
For instance,
• engine condition during various temperatures of operation
• ABS
