Configuration and Resource Classes

The configuration and resources classes provide access to a centralized database where type specific information can be stored and received. The uvm_resource_db is the low level resource database which users can write to or read from. The uvm_config_db is layered on top of the resoure database and provides a typed interface for configuration setting that is consistent with the <uvm_component::Configuration Interface>.

Information can be read from or written to the database at any time during simulation. A resource may be associated with a specific hierarchical scope of a uvm_component or it may be visible to all components regardless of their hierarchical position.
