Hi, all When i read the uvm source code, I had a puzzle as follow: Why are the twelve runtime phases added into m_uvm_schedule phase instead of being added directly m_uvm_domain domain in file uvm_domain.svh? static function void add_uvm_phases(uvm_phase schedule); schedule.add(uvm_pre_reset_phase::get()); schedule.add(uvm_reset_phase::get()); schedule.add(uvm_post_reset_phase::get()); schedule.add(uvm_pre_configure_phase::get()); schedule.add(uvm_configure_phase::get()); schedule.add(uvm_post_configure_phase::get()); schedule.add(uvm_pre_ma

getvictor, Thanks for your reply. BR QIN

Would you like to us when we get it?

Hi, all Thanks for your valuable informaiton. It is very useful to understand the cast operation. Thank you again. BR QIN

Hi, Alan I modified the code as you said above, it worked well. Thank you for your value information. BR QIN

Hi, Zhuang Thank you for your value information. I also want to know what the assignment of P1 with P2 does? BR

Hi, Zhuang I modified the source code as you said as follow: class BasePacket; int A = 1; int C = 2; function void printA; $display("BasePacket::A is %d", A); endfunction : printA virtual function void printC; $display("BasePacket::C is %d", C); endfunction : printC endclass : BasePacket class My_Packet extends BasePacket; int A = 3; int C = 4; function void printA; $display("My_Packet::A is %d", A); endfunction: printA virtual function void printC; $display("My_Packet::C is %d", C); endfunction : printC endclass : My_Packet BaseP

Hi, all //Case One class BasePacket; int A; endclass : BasePacket class My_Packet extends BasePacket; int C; endclass : My_Packet class BaseTest; BasePacket PB[string]; virtual function void Create_PKT(string s); PB = new(); endfunction : Create_PKT virtual function void Configure_PKT(string s); PB.A = 1; endfunction : Configure_PKT virtual function void printP(string s); $display("BaseTest::PB[%s].A is %d", s, PB.A); endfunction : printP endclass : BaseTest class My_Test extends BaseTest; virtual function void Create_PKT(string s); My_Packet MP =

Hi, all I has an example as follow: class BasePacket; int A = 1; int C = 2; function void printA; $display("BasePacket::A is %d", A); endfunction : printA virtual function void printC; $display("BasePacket::C is %d", C); endfunction : printC endclass : BasePacket class My_Packet extends BasePacket; int A = 3; int C = 4; function void printA; $display("My_Packet::A is %d", A); endfunction: printA virtual function void printC; $display("My_Packet::C is %d", C); endfunction : printC endclass : My_Packet BasePacket P1 = new; M

when the m_pool.add(obj, q) is called by the function add(T obj, uvm_callback cb, uvm_apprepend ordering=UVM_APPEND) in the class uvm_callbacks #(type T=uvm_object, type CB=uvm_callback), if q (i.e the entry you said) is null, the q will be newed, i.e the q (the entry) is not null.

Hi, all There is a piece of code in the function m_add_tw_cbs of the uvm_typed_callbacks#(type T=uvm_object) of the file uvm_callback.sv as follow: if(m_t_inst.m_pool.first(obj)) begin do begin if($cast(me,obj)) begin q = m_t_inst.m_pool.get(obj); if(q==null) begin q=new; m_t_inst.m_pool.add(obj,q); end if(m_cb_find(q,cb) == -1) begin if(ordering == UVM_APPEND) q.push_back(cb); else q.push_front(cb); end end end while(m_t

Hi, all We have one monitor and one driver as follow: class monitor extends uvm_monitor; `uvm_component_utils(monitor) function new(string name, uvm_component parent); super.new(name, parent); endfunction virtual task post_shutdown_phase(uvm_phase phase); #50ns; `uvm_info(get_type_name(), "Monitor is printing at post_shutdown_phase executing...", UVM_LOW ) endtask: post_shutdown_phase virtual function void phase_ready_to_end(uvm_phase phase); if(phase.get_name == "post_shutdown") `uvm_info(get_type_name(), "Monitor is printing

Hi, all Why is not the 12 realtime phases directly wrapped by m_uvm_domain but also the m_uvm_schedule is inserted between m_uvm_domain and the 12 realtime phases? Thank you in advanced! BR QIN

Thanks Dave_59 for your reply！ BR QIN
