verilog task

Hi,

is there a way to determine whether a task is being run?

Thanks,
e.

Hi,

I have verilog tasks which handle ring bus access to components.
I don't want to rewrite them, but to call them from C testbench.

Thanks,
Dominique

I am not sure exactly what you are asking. Are you trying to find out
whether a task has been called because your simulation does not seem to
be behaving correctly?

You can put a $display into the task to print something whenever it
executes. In an interactive debugging session in your simulator, you
should also be able to put a breakpoint in the task to see if it
executes.

 

Hi,

actually what I wanted is to chek whether the task is running and
depending on that to run some different code or not.

Use external-to-task register to achieve this:

reg my_task_running = 0;


task my_task;
.....
begin
my_task_running = 1;

......

my_task_running = 0;
end
endtask

Then, observe my_task_running register for your calculations.

Supposing this task is running as a testbench element, you can define
identifiers of type "event":

event task_active_flag;
...

task my_task;
begin
-> task_active_flag;
end

....

then

always @(task_active_flag)
<do some jobs>;
