You can also set the simulation speed before you start a program:
U Switch to the next soft-key row
U Select the function for setting the simulation speed
U Select the desired function by soft key, e.g.
incrementally increasing the test speed
The most recently set speed remains active, even if the
power is interrupted, until you change it.
Functions Soft key
