而通过interface,便可以解决这些问题,interface包含了连接,同步,甚至是两个或者多个块之间的通信,只要在interface里面声明过的信号与端口,在其它模块都可以共用。 (2)使用clocking block,可以保证测试平台在正确的时间点与信号交互,而不只是随着一个同步时钟采样与验证,一个时钟块,可以对应一个时钟域。 3、以下代码中,...

即可。2.最简单的UVM 平台,一个interface ,一个DUT ,一个TOP ,一个test ,一个ENV 就可以工作了,然后慢慢的添加各个component ;3.写interface 4.写top module ,在top 中例化DUT ,interface 和DUT 在top 中 include uvm_config_db#(virtual ubus_if)::set(uvm_root::get(),"*","vif",vif);
