Are task and function belong to process?

is task and function belong to process?

In SV-2009, section 9.5 refer to as follows:

9.5 Process execution threads

SystemVerilog creates a thread of execution for the following:

— Each initial procedure

— Each final procedure

— Each always, always_comb, always_latch and always_ff procedure

— Each parallel statement in a fork-join (or join_any or join_none) statement group

— Each dynamic process

Are task and function belong to process?

The is really a SystemVerilog question, not a base class library question. Next time please use the appropriate forum.

A task or function call does not create a new process; it is executed by the same process that calls it.

Some people think that the task calls below are creating new processes:

fork

task_call1;

task_call2;

join

But the way to read this is that each statement inside fork creates a new process. In this example, a process is created for each statement, and then each process executes a task call.
