return task_tgid_vnr(current); // returns current->tgid } 1. 2. 3. 4. 其中asmlinkage是一个指令,用于告诉编译器在stack上查找函数的参数,system call都需要设置;其次,getpid返回值是一个long类型,是为了兼容32bit和64bit;再次,所有system call的实体都是sys_##name这种形式
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仿真时添加编译option: +vc C/C++ source files; (1) +vc选项后面跟的源文件必须是.c后缀; (2) 注意现在如果使用+vc选项,vcs log中会报w...
Tasks and functions may be declared as automatic. Variables declared in anautomatictask, function, or block arelocal in scope, default tothe lifetime of the call or block, andare initialized on each entry to the call or block. An automatic block is one in which declarations are automatic by...
A reference is only valid during an active call of that task/function. A block with a static lifetime means that the variables inside the block, as well as arguments to tasks and functions, are all allocated and initialized at time 0 (Verilog is designed for hardware…). Example of ...

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...
