Hi All, It seems that there is a problem for automatically updating components fields registered with uvm_field_* macros. It works fine if the field is of type int, but it fails if the field is of type enum. Do I miss something? (I tested this code with both UVM 1.1-d and UVM 1.2) class hs_driver extends uvm_driver #(hs_packet); hs_type_t driver_type; int my_param = 10; `uvm_component_utils_begin (hs_driver) `uvm_field_enum (hs_type_t, driver_type, UVM_ALL_ON) `uvm_field_int (my_param, UVM_ALL_ON) `uvm_component_utils_end [...] endclass: hs_driver class test_bench extends uvm_component; `uvm_component_utils (test_bench) hs_driver host; hs_driver device; [...] virtual function void build_phase(uvm_phase phase); super.build_phase(phase); uvm_config_db#(hs_type_t)::set (null, "*.device", "driver_type", DEVICE); uvm_config_db#(int)::set (null, "*.host", "my_param", 888); host = hs_driver::type_id::create ("host", this); device = hs_driver::type_id::create ("device", this); endfunction: build_phase endclass: test_bench Printing test topology: ------------------------------------------------------------- Name Type Size Value ------------------------------------------------------------- uvm_test_top simple_test - @1863 mtb test_bench - @1939 device hs_driver - @2089 rsp_port uvm_analysis_port - @2162 recording_detail integral 32 'd1 seq_item_port uvm_seq_item_pull_port - @2130 recording_detail integral 32 'd1 driver_type hs_type_t 32 HOST -> should have been DEVICE! my_param integral 32 'ha recording_detail integral 32 'd1 host hs_driver - @2024 rsp_port uvm_analysis_port - @2095 recording_detail integral 32 'd1 seq_item_port uvm_seq_item_pull_port - @2058 recording_detail integral 32 'd1 driver_type hs_type_t 32 HOST my_param integral 32 'h378 -> In this case (for an integer) the field has been updated followin uvm_config_db recording_detail integral 32 'd1 recording_detail integral 32 'd1

When agents are configured, I typically see something like this: uvm_config_db#(int)::set(this,"testbenchA.masterA_hostB.agentpink","is_active",UVM_ACTIVE); Isn't UVM_ACTIVE of type bit? I see it 'described' here in an enum and given a default value. src/base/uvm_object_globals.svh: typedef enum bit { UVM_PASSIVE=0, UVM_ACTIVE=1 } uvm_active_passive_enum; So shouldn't the uvm_config_db line not be: uvm_config_db#(int)::set(this,"testbenchA.masterA_hostB.agentpink","is_active",UVM_ACTIVE); but instead be: uvm_config_db#(bit)::set(this,"testbenchA.masterA_hostB.agentpink","is_active",UVM_ACTIVE); ? thx, (I sense that I probably don't have a solid enough understanding of enum and the relationship between bits and ints.)
