The complexity among embedded systems has increased dramatically in recent years. During the same time has the capacity of the hardware grown to astonishing levels. These factors have contributed to that software has taken a leading role and time-consuming role in embedded system development.Compared with regular software development, embedded development is often more restrained by factors such as hardware performance and testing capability. A solution to some of these problem has been proposed and that is a concept called virtual platforms. By emulating the hardware in a software environment, it is possible to avoid some of the problems associated with embedded software development. For example is it possible to execute a system faster than in reality and to provide a more controllable testing environment. This thesis presents a case study of an application specific virtual platform. The platform is based on already existing embedded system that is located in an industrial control system.  The virtual platform is able to execute unmodified application code at a speed twice of the real system, without causing any software faults. The simulation can also be simulated at even higher speed if some accuracy losses are regarded as acceptable.The thesis presents some tools and methods that can be used to model hardware on a functional level in an software environment. The thesis also investigates the accuracy of the virtual platform by comparing it with measurements from the physical system. In this case are the measurements mainly focused of the data transactions in a controller area network bus (CAN).

TSP (or Telecommunication Server Platform) is a scalable, high availability cluster operating system developed by Ericsson for use in the telecommunications industry. This thesis describes an attempt to simulate a TSP cluster in the full system simulator Simics, and talks about some of the possibilities offered by such a setup and full system simulation in general. This attempt to simulate TSP was unsuccessful in completely booting the cluster in Simics, but some of the experiences and problems encountered are described. A proposed development environment for working with TSP in Simics is also presented, along with scripts that were created during this thesis to alleviate the working process. / TSP (eller Telecommunication Server Platform) är en skalbar, högt tillgängligt kluster-operativsystem utvecklat av Ericsson för användning inom telekommunikationsindustrin. Den här rapporten beskriver ett försök att simulera TSP-kluster i full-system simulatorn Simics, och beskriver en del av de möjligheter med detta och full-system simulering i allmänhet. Det här försöket att simulera TSP lyckades inte att fullständigt boota klustret i Simics, men några av de erfarenheter och problem som stöttes på är beskrivna. En föreslagen utvecklingsmiljö presenteras också, tillsammans med script som skapades under det här arbetet för att underlätta arbetet. / Olle Eriksson, Contact info at www.olle-eriksson.com Emil Erlandsson, Contact info at www.buglix.org
