uvm_utils #(TYPE, FIELD)类包含很有用的模板功能。 其中find_all method可以由start组件开始向下递归地找到所有参数类型为TYPE的组件实例。 *此处附一则find_all的使用示例:使用find_all通过关键字查找并自动连接sequencer,有趣的用法。 其中get_config method用来获得与组件comp相关联
2.直接在seq内获取要交互的uvc的hierarchy (1) 需要在seq的pkg内include uvc的相关pkg; (2) 采用uvm_root的find方法以及components例化名,获取uvc的handle. 补充:uvm_root.find/find_all的介绍 find/find_all的源码如下: 3.借助config_db机制 3.1在sequence中获取参数 (1) 能够调用config_db::get的前提是已经...
// hierarchical name. See <find> and <find_all>. // // Report configuration - Use ~uvm_top~ to globally configure // report verbosity, log files, and actions. For example, // ~uvm_top.set_report_verbosity_level_hier(UVM_FULL)~ would set ...
Phase control:uvm_top 管理所有components的phase运行。 search:可以使用uvm_top 基于层次结构搜索components,具体参考后面的find和find_all方法。 Report configuration:使用uvm_top 全局配置report verbosity,log files等。 例如:uvm_top.set_report_verbosity_level_hier(UVM_FULL) // 仿真中所有components的verbosity设...

find function uvm_component find ( stringcomp_match ) find_all function void find_all ( stringcomp_match, refuvm_componentcomps[$], inputuvm_componentcomp=null ) Returns the component handle (find) or list of components handles (find_all) matching a given string. The string may contain the...
`uvm_error("VIF_GET","Unable to find the SFR virtual interface in the uvm_config_db",UVM_LOW)end 请注意以下几点: uvm_config_db::get()方法是一个函数,它返回一个单bit值来指示对象检索是否成功;这将用于检查,以确保在查找失败时testbench不会继续运行。
