    报告路由、verbosity 与文件配置

    环境：VCS W-2024.09-SP2-8。1.2 使用 uvm-1.2，2.0 使用 uvm-ieee-2020-2.0。

    实验检查观察值是否符合预期；成功复现问题不代表问题已修复。

    结果对比

    观察内容 UVM 1.2 UVM 2.0
    调用报告接口前的 handler 状态 handler_before_api 1 0
    调用报告接口后的 handler 状态 handler_after_api 1 1
    report_summarize(0) 的屏幕输出记录 summary_zero_display 1 0
    report_summarize(0) 的文件输出记录 summary_zero_log 0 1
    总结后修改的文件路由仍保留（1=是） summary_file_persists 0 1
    显式恢复原文件路由成功（1=是） summary_file_restored 1 1
    verbosity=UVM_NONE 时输出总结的记录 summary_at_none 0 1
    设置工厂覆盖时的报错数 factory_set_errors 1 0
    工厂解析覆盖目标时的报错数 factory_resolve_errors 0 1

    运行命令

    目录与环境准备；从解包根目录执行：
