UVM guide line

• Naming rule
• axi_package, axi_monitor.svh
• how to debug
• if (debug) `uvm_info("DEBUG", msg, UVM_MEDIUM)
• uvm_factory  factory = uvm_factory.get(); factory.print();
• uvm_top.print_topology()
• how to trace connection 
• use "get_connect_to()", "get_provide_to()", children[$]
• 
  // If there is something connected,
  // print the port name and the connections. 
  if ((connected_to_list.size() > 0) || (provided_to_list.size() > 0) ) begin 
  // Print the name of the port. $display("%s Port: %s", {depth+2{" "}},
  children[i].get_full_name()); end 
  
• how to trace transactions
• use backdoor to log the analysis point
• fifo.put_export.debug_connected_to(); fifo.put_export.debug_provided_to();
• $display("%s", tx_queue[tx_id].convert2string());
• atomic transaction items(active sequence)
• use "pre_body()" phase to add new sequence
• use "post_body()" phase to remove sequence
• active_sequenves::show();
• internal BB(break) point(assertion pp)
• `define BB if (BB::check_pp1( tx, get_full_name()) $stop;
• use "grep" command to filter out the useful info
• grep "type_id::create" xx.log
• use report catcher without default UVM_report, collect the report pool meg to our report format
• function action_e catch();
• id = get_id(); 
• filename = get_fname(); 
• line = get_line(); 
• severity = get_severity();
• $dispay("%s...,", id);
• use report server to overwrite the report
