OVM Env Example :

`ifndef __MEM_ENV__
`define __MEM_ENV__

class mem_env extends ovm_env;

    protected virtual interface mem_if m_if ;

    mem_master_monitor m_monitor;
    mem_master_sequencer m_sequencer;
    mem_master_driver m_driver;

    `ovm_component_utils_begin(mem_env)
    `ovm_component_utils_end
    
     // new - constructor
     function new(string name, ovm_component parent);
        super.new(name, parent);
     endfunction : new

     // Function to assign the virtual intf for all components in this env
     function void assign_vi(virtual interface mem_if mif);
        $display ("INSIDE ASSIGN MEM_ENV \n");
        m_if = mif ;
        if( m_monitor != null) begin
            m_monitor.assign_vi(mif);
        end
        m_sequencer.assign_vi(mif);
        m_driver.assign_vi(mif);
    endfunction : assign_vi

    function  void build();
        string inst_name;
        super.build();
        $display ("INSIDE ASSIGN BUI:D \n");
        m_monitor = mem_master_monitor::type_id::create("m_monitor", this);
        $display ("INSIDE ASSIGN BUI:D 1 \n");
        m_driver = mem_master_driver::type_id::create("m_driver", this);
        $display ("INSIDE ASSIGN BUI:D 2 \n");
