jao16 Posted October 27, 2011 Report Share Posted October 27, 2011 Hello Hello all I am defining a test library as such: package my_test_lib_pkg; class my_test_base extends uvm_test; `uvm_component_utils(my_test_base) // declare an instance of the configuration, environment and agent classes my_cfg cfg_0; my_env env_0; my_agent agent_0; // constructor function new(string name = "my_test_base", uvm_component parent_null); super.ew(name, parent); endfunction : new // Now defining the build() phase. // In the build() phase, i would generate the above classes as such: function void build(); cfg_0 = my_cfg::type_id::create("cfg_0", this); env_0 = my_env::type_id::create("env_0", this); agent_0 = my_agent::type_id::create("agent_0", this); endfunction : build However, in some case i have seen the following code to generate the required instances: cfg_0 = new(); env_0 = new(); agent_0 = new(); So my question is a) what is the difference between create() and new() ? when should one use create() instead of new() and vice versa Thanks in advance JO Quote Link to comment Share on other sites More sharing options...
