Abstract
This article proposes a framework for anticipating verification and validation activities in the development of real-time embedded systems of space products. The purpose is to detect implementation and integration errors in an early stage of the development lifecycle, in order to reduce costs and time delays. The framework, named Embedded System Incremental Verification (ESIV), combines the following environments: a Model-in-the-Loop (MIL), a Software-in-the-Loop (SIL), and two Hardware-in-the-Loop (HIL). The MIL environment runs in a single computer and is composed of a simulation model of the control law and the flight dynamics. Following, the SIL environment uses two desktop computers: one for the flight dynamics and another for running in real-time an early version of the on-board software. The first HIL includes a preliminary version of the on-board computer, a desktop to emulate sensors, actuators and the ground station, and second desktop for the flight dynamics. Finally, the second HIL uses the real sensors and actuators, the final version of the flight computer and the ground station equipment. The proposed framework is successfully applied to the on-board computer of the microgravity suborbital platform with the purpose of avoiding failures during the launch.
