回调函数的接口通常是预先定义好的,比如CC总不能给主函数注册一个“由民警配送到我家”的回调函数吧。 词条定义:最后再来看看在wikipedia上的词条定义: “In computer programming, a callback is any executable code that is passed as an argument to other code; that other code is expected to call back (...
在constraint内调用function就称为”function in constraints”。它的格式如下: constraintconstraint_name {rand_var== function_call(arguments...); } function的定义写在constraint block之外,它内部包含了对arguments的处理。 在调用randomize()的时候,function会先被求解,function的返回值将会作为state variables去参与...

由於struct s_vpi_systf_data規定自訂的C function的signature必須為PLI_INT32 (*calltf)(PLI_BYTE8 *),所以依照其規定宣告hello_world型別。 24行 //associating C function with new verilog system task //you can use your favorite function name voidregister_my_systfs() { s_vpi_systf_data tf_da...
Verilog PLI(Programming Language Interface)是Verilog所提供的機制,我們可以使用C語言開發自己的system task/function,以彌補在Verilog撰寫testbench的不足。 在此文件,將學習到: 1.如何在Verilog呼叫C function? 2.如何撰寫簡單的calltf routine與register function?
Instead of storing in analysis_fifo, I am calling the function to update the id status on-the-fly. I still can’t see how using a semaphore is going to help you? Where would you call the put() and get() if you were allowed to call a task from a function? → I am using the ...
这个错误通常出现在SystemVerilog或UVM(Universal Verification Methodology)的仿真环境中,尤其是在调用任务(task)或函数(function)时。 错误含义: “incompatible complex type usage in task or function call”意味着在调用任务或函数时,传递的实际参数(actual parameter)的类型与任务或函数定义中的形式参数(formal para...
