Debug topology and Check config usage in UVM

Topology of the test

function void test_base::start_of_simulation_phase(uvm_phase phase);
	uvm_root::get().print_topology(); // defaults to table printer
endfunction

The default printer policy is uvm_default_table_printer

There are three default printer policies that the uvm_pkg provides:

uvm_default_table_printer uvm_default_tree_printer uvm_default_line_printer

Check all configuration settings

Check all configuration settings in a components configuration table to determine if the setting has been used, overridden or not used. When recurse is 1 (default), configuration for this and all child components are recursively checked. This function is automatically called in the check phase, but can be manually called at any time.

To get all configuration information prior to the run phase, do something like this in your top object:

function void start_of_simulation_phase(uvm_phase phase);
	check_config_usage();
endfunction

UVM phase

• Functions are executed bottom-up (Except for build and final phases , which are executed top-down)
• Tasks are forked into concurrent executing threads
