dc.description.abstractNetwork-on-Chip (NoC) is a power architecture that emerged to solve communication issues present in modern Systems-on-Chip (SoCs). NoC based architectures are very scalable and offer high levels of communication parallelism, among other features. Every efficient NoC implementation requires several design steps to accomplish indices of performance. Although there are many system level models, high-level models for NoC are representative in the context of design since they provide fast and accurate analysis, with low modeling effort, for further VHDL implementations. This work proposes a NoC model based on a Timed Colored Petri Net (TCPN) that computes performance indices seamlessly. Network latency and buffer occupation are of special interest in our approach as they represent the key indices when assessing NoC performance. As results, we have validated and refined the model of a 5×5 mesh NoC comparing its indices with equivalent VHDL RTL description under synthetic and real traffic situations. The proposed model is capable of analyzing the influence of the router service time on the average latency time, enabling internal NoC evaluation to optimize buffer length. Simulation results demonstrate the model suitability for latency evaluation with time estimation errors often below 1%. Furthermore, this paper discusses the effort required to extend the model with other NoC architectural features. We conclude that the use of a TCPN model of NoC generates accurate results providing as much detailed information as their equivalent experiments using VHDL description.
