The problem of the global clock distribution on multicore systems has rightly abandoned the use of synchronous interconnection networks, but increased the design complexity of the clocked islands. In this work, the design of a completely asynchronous router, with multiple arbitration paths, is presented in detail. The data flow between all the heterogeneous components is based on four-phase handshake protocol. We simulate two 2D mesh networks of different sizes, and propose an evaluation methodology for each of the two important properties: deadlock freedom and reachability. Simulation results show that our networks satisfy both of these properties even against a reasonable flit-injection rate. The inter-router communication is also based on the same single rail, return to zero protocol.
