I am trying to change the UVM verbosity of the simulation after satisfying certain conditions. Verbosity options of different components are passing through the command line as +uvm_set_verbosity. Once the conditions are satisfied, then the simulations should run with the the command line +uvm_set_verbosity option. Till then simulation runs with low verbosity for all components.
Looking through the UVM library code, it appears that there is a function called m_set_cl_msg_args(). This function calls three other functions that appear to consume the command line arguments like: +uvm_set_verbosity, +uvm_set_action, +uvm_set_severity.
So what I did was get the uvm_root instance from the uvm_coreservice singleton, and then use the get_children() function from uvm_component class to recursively get a queue of all of the uvm_components in the simulation. Then call the m_set_cl_msg_args() function on all of the components.
My code looks like:
cs_t = uvm_coreservice_t::get();
r = cs_t.get_root();
Even though this code compiles properly, But this is not changing verbosity. Any idea ?
Moreover I am able to print all the components in array_uvm. So I am guessing
array_uvm[i].m_set_cl_msg_args();this as a wrong call.
Anyone have any other suggestion to change verbosity during run time.
