VC arbitration algorithm.
Virtual channel arbitration
Input: header flits
/*Control signal enable*/
(1)   while (header flits) do
(2)   use lottery arbitration to select local and global highest priority flits

(6)   = global input virtual channel address}
(7)   end while
/*Channel switch*/
(8)   Case
(9)    = local packet of
