HIL TEST ?
Hardware-in-the-loop (HIL) simulation, or HWIL, is a technique that is used in the development and test of complex real-time embedded systems. HIL simulation provides an effective platform by adding the complexity of the plant under control to the test platform. The complexity of the plant under control is included in test and development by adding a mathematical representation of all related dynamic systemso.
In many cases, the most effective way to develop an embedded system is to connect the embedded system to the real plant. In other cases, HIL simulation is more efficient. The metric of development and test efficiency is typically a formula that includes the following factors: 1. Cost 2. Duration 3. Safety 4. Feasibility
The cost of the approach should be measure of the cost of all tools and effort. The duration of development and testing affects the for a planned product. Safety factor and development duration are typically equated to a cost measure. Specific conditions that warrant the use of HIL simulation include the following:
• Enhancing the quality of testing
• Tight development schedules
• High-burden-rate plant
• Early process human factor development
