TheConfigD()uses a combination of a handle to a UVM component and a string to create a UVM path both to store data in theConfigDB()and to retrieve it. The first two arguments to both theset()andget()functions are the component and the string path. Here is how this applies to the ...

The goal of this paper is to demystify the uvm_config_db for the novice user. This paper will examine the functionality of the uvm_config_db starting with its relationship to the resource database. It will discuss how the database is implemented in the UVM library, and it will explore ...

这个示例介绍UVM的自动(automated)配置功能,具体讲就是只需要使用uvm_config_db# ()::set()来配置参数,无需自己调用对应的get()来手动获取配置数据。 那么,UVM内部是如何实现自动获取配置参数的呢?我们在使用的时候需要注意什么?接下来我们一起来看一下: ...
uvm_config_db#(jelly_bean_env_config)::set(.cntxt(this),.inst_name("*"),.field_name("jb_env_cfg"),.value(jb_env_cfg)) Theuvm_config_dbis a parameterized class. In the above code, theuvm_config_dbis specialized with thejelly_bean_env_configtype. Thecntxt(context) andinst_name...
