当仿真运行到 illegal functional coverage bin,将会继续运行 -covg_disable_cg 关闭所有的功能覆盖率covergroups -covg_dump_range 保存bin的定义,配合urg的-group show_bin_values,将会把bin的定义生成到report中 实用的选项: -covg_disable_cg编译选项、仿真选项 若作为编译选项,则关闭covergroup并忽略其实例相关...

Stimulus Coverage 先编写功能覆盖率组pkt_cg,将packet作为参数传进去; 再编写一个独立的组件packet_coverage,实现覆盖率的采样; 最后在测试用例中,声明并实例化packet_coverage,在connect_phase中将agent里边monitor收集的数据包,通过TLM连接到packet_coverage中去采样。 Correctness Coverage 先编写功能覆盖率组sb_pkt_cg...
