注1:调用关联导入方法时,需要记录调用的上下文环境以决定调用PLI TF\ACC还是VPI方法或者导出的system verilog任务,会给仿真器带来额外的开支; 注2:导入函数的上下文是该函数定义所在的位置,比如$unit、模块、program或者package; 1使用格式:2import"DPI-C"context task call_sv(bit[31:0] data); 3.1.3 vcs仿真...

When you declare a class in a package, the package name becomes a prefix to the class name (it could useful to isolate different class/functions/task/etc.. that have the same but serve different functions): Now there are two definitions of class A, one called P::A and the other called...

Structures can be passed as arguments to a task or function. To do so, the structure must be defined as a user-defined type using typedef, so that the task or function argument can then be declared as the structure type. moduleprocessor (...); ...
I'm wondering if there is any ability to call a SystemVerilog/UVM Task/Function from Cocotb. Instead of living in purely Cocotb, or purely UVM, is it possible from the python side to direct and control the simulation? Say I start my test by calling a Cocotb async routine, then I want...
Unlike SystemVerilog functions, we can call another task from within a task. We can also make calls to functions from within a task. SystemVerilog Task Example Let’s consider a simple example to better demonstrate how to write a SystemVerilog task. ...
