Dynamic Configuration Change

UVM

Hi All,

I have a requirement, where I have dynamically change configuration, while traffic is in progression. Can any one give me some idea about the best possible, way to do the same.

You can try this with a Singleton class. It does not have overhead of uvm configuration database.

class MyObject;

   int configuration_1;
   int configuration_2;

   static MyObject myObj;

   // Making constructor local restricts
   // any call to new() outside of the
   // class
   local function new();
   endfunction

   // Creator method
   static function MyObject getObject();
      if(myObj == null)
         myObj = new();
      return myObj;
   endfunction

endclass //MyObject


initial
begin
  // Use this to get the shared object
  MyObject obj = MyObject::getObject();
end

Could you please explain some more details. Does your configuration data depend on pattern generated or how does it work?

Hi,

The requirement is, I am working on PCI-E protocol in GEN-3 and I want to configure my ports in GEN-2, while PCI-E frames are in progress. I want to know, how to pass GEN-2 configuration using config_db or some other feature in UVM, while frames are moving.

I guess you have a limited number of configurations. In this case you could put these config objects to the config_db, prior to starting any traffic. Another option I see is to pass configuratioon data along with an event.
