Today's Cyber-Physical Systems (CPS) are witnessing a growing
complexity in terms of the number of components and computational
power in order to meet the requirements of nowadays applications.
For this reason and due to their energy efficiency,
Multiprocessor system-on-chips (MPSoC) are becoming
ubiquitous. Yet, since these systems are often used in
battery-driven and/or small housing use cases, the correct
configuration of their power management techniques is
an important factor in system design and can be related
to possible safety aspects of the system.
This calls for an adequate test framework, which is able
to observe the power management functionalities of CPS,
even before the actual hardware platform is available.
The use of virtual platforms for functional validation,
that allows executing the CPS's real target platform compatible
application binary code on a generic host computer, is currently
being adopted by the industry.
This work focuses on enhancing industrial OVP virtual platforms by
a functional test framework of the power management techniques.
We will demonstrate and evaluate how this framework maintains to observe the power
management techniques of the system under test. The
evaluation uses a Xilinx ZC702 board based on a Xilinx Zynq-7000
MPSoC and its correspondent virtual platform in OVP.
Results show that the functional test framework is able
to analyze the different modes of operation regarding the
power management techniques of the Xilinx Zynq processing
