Hi All,

I am looking for a solution that start() the flow graph for a definite
period of time (in seconds) and after that it stop() it automatically. For
example

# let suppose initial value of time is 14 seconds; it means that the
flowgraph defined in tb1 should need to executed during that time; and when
the time reaches zero it must be stop.

while 1:
    if (time!=0):
          tb1.run()
          time = int(time) - int(1)
    elif (time==0):
          tb1.stop()


I tried this; but once the flow graph started; then it never comes to the
elif condition. How can I stop() the flowgraph in this condition. Waiting
for reply.

Regards,
