    The Verification Academy offers users multiple entry points to find the information they need. One of these entry points is through Topic collections. These topics are industry standards that all design and verification engineers should recognize. While we continue to add new topics, users are encourage to further refine collection information to meet their specific interests.

    The Verification Academy is organized into a collection of free online courses, focusing on various key aspects of advanced functional verification. Each course consists of multiple sessions—allowing the participant to pick and choose specific topics of interest, as well as revisit any specific topics for future reference. After completing a specific course, the participant should be armed with enough knowledge to then understand the necessary steps required for maturing their own organization’s skills and infrastructure on the specific topic of interest. The Verification Academy will provide you with a unique opportunity to develop an understanding of how to mature your organization’s processes so that you can then reap the benefits that advanced functional verification offers.

We have more than 500 components(agents,drivers,monitors etc) in our test bench.
We get a lot of displays from each of them usnig uvm_info
Is it possible to disable/enable display from a particular component.
PS- All components have same verbosity

For uvm_info the default action is UVM_DISPLAY. If you want to take some other actions we can take it by id by using the method set_report_id_action. The other actions can be UVM_LOG, UVM_EXIT, UVM_NO_ACTION.
So now if the messages have to be turned off we can set action has UVM_NO_ACTION.

comp_handle.set_report_id_action("ID",UVM_NO_ACTION);

In reply to shanthi:

I want to suprress all displays from command line. I am using
+uvm_set_action=*,_ALL_,UVM_INFO,UVM_NO_ACTION

but it is not working

#This should Turn off all INFO messages everywhere
#uvm_cmdline = +uvm_set_action=*,_ALL_,UVM_INFO,UVM_NO_ACTION

But uvm_info where there is no ID are being displayed

In reply to Jack Bryan:

If you want to disable the infos in all the components then you can use

 +uvm_set_action=*,_ALL_,UVM_INFO,UVM_NO_ACTION

If you want to disable only in a particular component, you need to mention the component hierarchical path as shown below

 +uvm_set_action=uvm_test_top.ahb_top.ahb_agt.ahb_drv,_ALL_,UVM_INFO,UVM_NO_ACTION

with the above command-line option all the info from ahb_driver will be turned off

+uvm_set_action=*,_ALL_,UVM_INFO,UVM_NO_ACTION

This is not working... can see the number of displays have reduced, but still i can see some displays. I dont know why
