  * ========
- * There are a number of different available NoC routing algorithms. The purpose of
- * this class is to construct the appropriate routing algorithm based on the user
- * specification in the command line. The user identifies a specific routing algorithm
- * in the command line by providing a string (which is the name of routing algorithm).
- * Then, the appripriate routing algorithm is created here based on the provided
