A detailed and flexible cycle-accurate Network-on-Chip simulator
Network-on-Chips (NoCs) are becoming integral parts of modern microprocessors as the number of cores and modules integrated on a single chip continues to increase. Research and development of future NoC technology relies on accurate modeling and simulations to evaluate the performance impact and analyze the cost of novel NoC architectures. In this work, we present BookSim, a cycle-accurate simulator for NoCs. The simulator is designed for simulation flexibility and accurate modeling of network components. It features a modular design and offers a large set of configurable network parameters in terms of topology, routing algorithm, flow control, and router microarchitecture, including buffer management and allocation schemes. BookSim furthermore emphasizes detailed implementations of network components that accurately model the behavior of actual hardware. We have validated the accuracy of the simulator against RTL implementations of NoC routers. © 2013 IEEE.
