HILS is a proven and essential part of the embedded product development life cycle which strives to reduce effort, time and cost spent on automotive validation activities. An efficient HILS system allows to create a precise simulation environment for the ECU which is made to believe that it is sitting inside a real vehicle and there by the intended functionalities implemented in the same could be tested even before the vehicle prototypes or other ECUs or sensors and actuators are available. An inefficient and faulty HILS system provides erroneous test results which could lead to wrong inferences. This paper is proposing a standardized process flow aided by specific documentation and design concepts which validates that the test system designed is robust and caters to the actual requirement. The Design stage starts by a requirement gathering phase where the analysis of the device under test is executed in detail.
