Hello again, so in this blog we will see a basic hello world example in UVM,
TB Architecture :
agent.sv
// class -> agent
// class -> env
// class -> test
// module -> top
class agent extends uvm_agent;
`uvm_component_utils(agent)
function new(string name="agent",uvm_component parent);
super.new(name,parent);
endfunction
function void build_phase(uvm_phase phase);
`uvm_info(get_type_name(), "Inside build phase", UVM_MEDIUM)
endfunction: build_phase
function void end_of_elaboration_phase(uvm_phase phase);
`uvm_info(get_type_name(), "Inside end of eleboration phase", UVM_MEDIUM)
endfunction: end_of_elaboration_phase
function void start_of_simulation_phase(uvm_phase phase);
`uvm_info(get_type_name(), "Inside start of simulation phase", UVM_MEDIUM)
endfunction: start_of_simulation_phase
function void report_phase(uvm_phase phase);
`uvm_info(get_type_name(), "Inside report phase", UVM_MEDIUM)
endfunction: report_phase
function void hello_world();
`uvm_info(get_type_name(), "----- HELLO WORLD -----", UVM_MEDIUM)
endfunction
endclass
env.sv
class env extends uvm_env;
`uvm_component_utils(env)
function new(string name="env",uvm_component parent);
super.new(name,parent);
endfunction
agent agent_h;
function void build_phase(uvm_phase phase);
`uvm_info(get_type_name(), "Inside build phase", UVM_MEDIUM)
agent_h=agent::type_id::create("agent_h");
endfunction: build_phase
function void end_of_elaboration_phase(uvm_phase phase);
`uvm_info(get_type_name(), "Inside end of eleboration phase", UVM_MEDIUM)
endfunction: end_of_elaboration_phase
function void start_of_simulation_phase(uvm_phase phase);
`uvm_info(get_type_name(), "Inside start of simulation phase", UVM_MEDIUM)
`uvm_info(get_type_name(), "----- calling : agent_h.hello_world();", UVM_MEDIUM)
agent_h.hello_world();
endfunction: start_of_simulation_phase
function void report_phase(uvm_phase phase);
`uvm_info(get_type_name(), "Inside report phase", UVM_MEDIUM)
endfunction: report_phase
endclass
test.sv
class test extends uvm_test;
`uvm_component_utils(test)
function new(string name="test",uvm_component parent);
super.new(name,parent);
endfunction

endfunction: build_phase
function void end_of_elaboration_phase(uvm_phase phase);
`uvm_info(get_type_name(), "Inside end of eleboration phase", UVM_MEDIUM)
endfunction: end_of_elaboration_phase
function void start_of_simulation_phase(uvm_phase phase);
`uvm_info(get_type_name(), "Inside start of simulation phase", UVM_MEDIUM)
endfunction: start_of_simulation_phase
task task run_phase(uvm_phase phase);
phase.raise_objection(this);
`uvm_info(get_name(), "<run_phase> started, objection raised.", UVM_NONE)
#10;
`uvm_info(get_type_name(), "Inside RUN phase", UVM_MEDIUM)
phase.drop_objection(this);
`uvm_info(get_name(), "<run_phase> finished, objection dropped.", UVM_NONE)
endtask: run_phase
function void report_phase(uvm_phase phase);
`uvm_info(get_type_name(), "Inside report phase", UVM_MEDIUM)
endfunction: report_phase
