verilog - 在 VCS 中获取系统时间

Question

有没有办法在 VCS/UVM 中获取系统时间？我正在寻找类似于 Perl 的 localtime(time) .有没有办法为每个 uvm_info 打印系统时间打印 ？

Answer 1

一种方法是使用 $system()运行任何系统命令，包括系统的日期命令。

initial
 begin
    $system("date");
 end

来自 IEEE 1800资源管理:

$system makes a call to the C function system(). The C function executes the argument passed to it as if the argument was executed from the terminal. $system can be called as either a task or a function. When called as a function, it returns the return value of the call to system() with data type int. If $system is called with no string argument, the C function system() will be called with the NULL string.
