The present disclosure provides computer-based methods and a system for synthesizing a NoC that advantageously generate balanced NoC topologies without end-to-end fairness or local credit-based arbitration, and improve NoC performance when destination device bridge ports support only one incoming physical link per channel. More particularly, a clock domain is assigned to certain routers that satisfies the minimum frequency for the router while reducing clock domain transitions to neighboring routers, and the traffic flows received by these routers are balanced based on the traffic flow packet rates.
