Dear all,
But the result is not right. The cnt became instable and crashed in the
second loop. And at that time the load is only about 1.6nN. Could you tell
me why it happen. Thank you
No one is likely to run a complicated input script you post and figure
out why it is "not right". You have to debug it yourself, starting
with simple systems and build it up one stage at a time.
