Clarification on the ESP NoC about esp HOT 1 CLOSED

Hi, thanks for your questions.

1. No, the NoC only supports a 2D mesh topology.
2. No, all flits have the same priority, and arbitration within the router is done in a round-robin manner.
3. The implementations are the same. The SystemVerilog implementation is now the default in te new release.
4. The current maximum is an 8x8 NoC. This is because the tile coordinates use 3 bit signals. In theory, the NoC can be expanded to be larger, though. Where do you see that the limit is 5x5?
5. Yes, the X and Y dimensions do not need to be equal.
6. No, the NoC only supports dimension-ordered routing.
