uvm_pkg——老板，打包带走

Thus spake the master programmer: “After three day without programming, life becomes meaningless.”

编程大师曰：“倘若三天不编程，生活将变得毫无意义。”

 

　　在SV中引入了package 的概念，可以使多个模块进行数据类型共享，使用作用域解析符对包进行引用（::）,从UVM 的包总来看主要包括：uvm_macros包含UVM的所有宏定义，dpi目录定义外部语言接口，base包UVM中基础的class，dap是Data Access Policy, tlm1 包含Tranaction layer model 1的类定义。comps定义所有UVM中所用的component. seq目录是sequence机制的实现，TLM2则是对TLM2机制的实现，reg包含寄存器模型的实现。
