Research the SpaceFibre standard at application the technology of virtual prototyping

Article is devoted to an actual problem task of the analysis of efficiency of application of the SpaceFibre standard, namely, mechanisms of ensuring the quality of service for transfer the stream data in the onboard computer networks having strict requirements by the time of their delivery that is critical for viability of onboard systems. The model of a prototype of system-on-crystal (SOC) functioning with application of the SpaceFibre standard - the network controller of memory - by means of programming languages, methodology and instruments of system design and virtual prototyping has been developed. These are such languages as TLM 2.0 and SystemC, OVP technology and the program Virtual System Platform (VSP) tools provided by the Cadence company. Use of the presented means has allowed to execute imitating modeling and to carry out the analysis of productivity of the controller. The received results have helped to find restrictions of the considered architecture of SNK. Program utilities of Cadence and Imperas have allowed to reduce design time. Use of the presented methodologies has helped to develop and debug tests and the built-in software of the developed SOC before release of a product from factory.
