However tasks can also be included via the `include compile directive. Often tasks are created in the file they are used in. Tasks can be automatic (see below for more detail).Tasks can use non-blocking and blocking assignments.Variables declared inside a task are local to that task.Tasks can drive global variables external to the task.Tasks can call other tasks and functions.Tasks can have time delay (posedge, # delay, etc).The order of inputs/outputs to a task dictates how it should be wired up when called.Tasks can have any number of inputs and outputs.It also makes the code much cleaner and easier to read. This reduces copy/paste errors in your code and allows quicker development time. Rather than rewriting code, one can just call the task. Tasks should be utilized when the same operation is done over and over throughout Verilog code. This is one of the main differences between tasks and functions, functions do not allow time delays. Tasks are very handy in testbench simulations because tasks can include timing delays. Tasks are sections of Verilog code that allow the Digital Designer to write more reusable, easier to read code.
