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
