“…The ECAD software HDLNoCGen [43] was developed in C#; it implements the presented NoC low-level modeling architecture and provides support for circulant topologies for a NoC [8], [49]. It includes components for setting up the generation of the model core, tools for collecting data from the model core, as well as tools for managing the generation of data packets:  model tuning module, which receives the necessary data for the parametric generation of the NoC communication subsystem, generates the core of the model, and also launches the model to obtain the working results;  data processing module, which is necessary to obtain the results of the model and generate test data for the submission to the model in real time, as well as to collect the results of the modeling and compare them with the results of high-level modeling.…”

This article proposes a Network-on-Chip (NoC) communication subsystem model on the basis of which the Electronic Computer-Aided Design (ECAD) architecture in the form of software is implemented. It makes it possible to automate the process of preparing and generating an HDL description of the NoC model in the Verilog language. It is shown that not in all cases it is required to model the entire NoC. Often, it is necessary to model its certain parts, such as a communication subsystem, routing algorithm, and traffic control system. The developed model allows modeling a parameterized NoC communication subsystem to obtain an estimate of the consumed logical blocks and registers required for prototyping the communication subsystem. All components of the communication subsystem are implemented as separate modules due to which the hardware costs for adding the necessary components for the study are reduced because of the absence of the need to completely rework the model program code every time. The effectiveness of using the developed ECAD and low-level modeling automation methods to study the work of routing algorithms for NoC topologies is demonstrated.INDEX TERMS electronic computer-aided design (ECAD), HDL, network-on-chip (NoC), modeling, RTL.

“…But they are obtained using the Newxim high-level simulator. This means that they do not take into account the hardware costs for the implementation of the algorithm, the evaluation of which is a separate complex task [ 46 ]. In addition, low-level simulation can help to more accurately evaluate the characteristics of the RS algorithm.…”

This article considers the usage of circulant topologies as a promising deadlock-free topology for networks-on-chip (NoCs). A new high-level model, Newxim, for the exploration of NoCs with any topology is presented. Two methods for solving the problem of cyclic dependencies in circulant topologies, which limit their applications for NoCs due to the increased possibility of deadlocks, are proposed. The first method of dealing with deadlocks is universal and applicable to any topology; it is based on the idea of bypassing blocked sections of the network on an acyclic subnetwork. The second method—Ring-Split—takes into account the features of circulant topologies. The results of high-level modeling and comparison of the peak throughput of NoCs for circulant and mesh topologies using deadlock-free routing algorithms are presented. It was shown that a new approach for routing in circulants (compared to mesh topology) shows up to 59% better network throughput with a uniform distribution of network load.
