-- Name:       Simple Digital Divider
-- 
-- Description:
-- The BIT-value signal CLK changes its value after 1 ms. This
-- signal is divided by the model DIVIDER(SIMPLE) using N=5. 
-- In an intervall of 10 ms there occur 5 pulses of CLK and one
-- pulse of the dividers output OUTP. The simulation should
-- run until 50 ms.
