Example of a UVM Agent Each agent should have a configuration object which will contain a reference to the virtual interface that can be used by its driver and monitor to access pin level signals. This object ca

agent包括一个封装了相应的一组接口信号的interface,monitor和driver的BFM,以及一个package,其中包含组成整个agent组件的各种类。agent本身是一个包含sequencer、driver和monitor的容器,也包含其他相关的验证组件,比如functional coverage collector 以及scoreboard(一般不会放置在agent内)。代理只是提供与“普通”类的对象相同AP...

对agent的任何引用都需要使用这个字符串名称。 即这个分层路径名由顶层test实例化名至当前组件的实例化名用(".")操作符逐级拼接。 // Hierarchical name example class spi_env extends uvm_env; apb_agent m_apb_agent; // Declaration of the apb agent handle // ... function void build_phase(uvm_...

As mentioned in the webinar, one solution is to group configuration variables together into a “config object”. For example, an agent config has its local parameters such as the active/passive enum, various address and data values, and the virtual interface. If each config object holds just ...
