Time stage: A "1" at the
input starts the element. If
the time <name>.t is
expired, the output becomes
"1" too. The time stage will
be reset by "0" at the input.
Thus the output will be set to
"0" at the same time.
Time stage minimum pulse
width: The pulse width
<name>.t will be started if a
"1" is feed to the input. By
starting <name>.t, the
output becomes "1". If the
time is expired, the output
becomes "0" independent
from the input signal.
