从上面这些UVM接口的输入端口类型为字符串就可以知道,这么做的话函数的输入是字符串而不是HDL(hardware description language, 硬件描述语言 )的层次结构(path)。 除此之外,使用uvm_hdl相关后门接口可以在case_lib包在package里访问RTL的信号,而常规SystemVerilog的force则不行,
在SystemVerilog中,force和release被广泛用于强制赋值,优先级高于assign和deassign,属于连续赋值语句。然而,force的值会一直保持,而deposit则仅设置值,该值可能被后续操作覆盖。UVM提供了类似的接口,但输入端口类型为字符串,而非HDL层次结构。因此,UVM的接口函数输入更为灵活。UVM通过uvm_hdl后门接口在...

In reply to dave_59: Thanks dave. I understood that, string datatype can not converted to integral type/reg only using system verilog. But can i do reverse? I have instance path(reg/intergral type) and can i convert that in to string using some beauty of system-verilog? Please suggest...
QS之force(1) force This command allows you toapply stimulus interactively to VHDL signals(not variables),Verilog nets and registers,and SystemC boundary types. It is possible to create a complex sequence of stimuli when the force command is included in a DO file....
