Timing Characteristics of Sensor Simulation in an HIL Environment

Abstract

A large number of different applications are associated with different types of embedded systems where sensors play the key role in the creating of a particular view of an environment a system is being operated in. Embedded systems are often characterized as the soft- or hard-real-time systems, with high requirements for safety, thus imposing strict requirements for the timing behavior and accuracy of sensors in order to ensure determinism and dependability of a system. At early stage of a system design, analysis or optimization, the satisfaction of the requirements can be checked with models of sensors. The authors aim to investigate the timing performance and accuracy achieved during simulation of the same sensor model implemented in two different ways: as a software artifact and as a field programmable gate arrays (FPGA) solution. This article constitutes a part of the research activities defined in [1].
