// Using the asynchronous virsion of the Concurrent round-robine dispatching

// algorithm for the 2-stage Clos can save some area but introduce a 5%

// `define ENABLE_CRRD

// for the SDM router using crossbars and the Clos router using CRRD

// algorithm, using the multi-resource match arbiter may save the area in

// set to enable channel slicing for fast data paths

`define ENABLE_CHANNEL_SLICING

// set to use the early acknowledge of lokkahead pipelines in the critical cycle

`define ENABLE_LOOKAHEAD

// always set in wormhole and SDM routers to enable the eof bit in data pipeline stages
