A flexible network-on-chip simulator for early design space exploration

The communication requirements of large multi-core systems are convened by on-chip communication fabrics generally referred to as networks-on-chip (NoC). We have designed a simulation environment that allows early exploration of the performance and cost parameters of network-on-chip communication architectures, which is able to handle arbitrary topologies and routing schemes. The simulator implements a flit-level message-passing mechanism and supports application data specified as input trace files or generated at run-time by synthetic traffic generators.
