bool Send(Flit flit)

Tries to send Flit. Returns true on success

bool CanReceive()

Returns true if Flit can be received

Flit Receive()

Returns Flit if receive succeed, otherwise returns invalid Flit instance

std::size_t GetFreeSlots(std::size_t vc)

Returns number of free slots in the Buffer for given virtual channel

Flit Front()

Returns front Flit from the Buffer of current virtual channel

void Skip()
