UVM Configuration

In UVM, configuration is the process of defining and modifying the properties of objects and components in the testbench. Configuration objects, which are derived from the uvm_object class, are used to store and distribute configuration information.

Creating Configuration Objects

A configuration object is a user-defined class containing properties that represent configuration settings. These properties can be any data type, and each property corresponds to a configuration setting that can be applied to a UVM component.

Setting and Getting Configuration

Configuration settings are set using the uvm_config_db class's set() method. The uvm_config_db is a centralized database that stores configuration information. The get() method is then used to retrieve the configuration settings.

Configuration Propagation

The UVM configuration mechanism automatically propagates configuration settings through the testbench hierarchy. This makes it easy to centrally manage configuration settings and apply them to components as needed.
