item_done的使用

從UVM library剪出

Function: item_done

//
// calls made by a sequence for this item will return.
//
// The current item is removed from the sequencer fifo.
//
// If a response item is provided, then it will be sent back to the requesting
// sequence. The response item must have it's sequence ID and transaction ID
// set correctly, using the <uvm_sequence_item::set_id_info> method:

//
// Before is called, any calls to peek will retrieve the current
// item that was obtained by . After is called, peek
