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...
动态生成的对象,可在不重新编译的情况下指定tests和testbench架构 由Agent, Driver, Monitor 和 BFM 构成的分层的testbench 对象之间的事务级通信(TLM) Testbench激励(UVM Sequences)与testbench结构的分离 2. DUT 本项目将通过一个简单的DUT即TinyALU,来对UVM展开学习,重点是在验证平台上,而不是设计本身。TinyAL...
UVM Agent UVM agent是用于给定逻辑接口(如APB或USB)的验证组件“套件”。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...
