Description

The step source output signal steps from the value before to the value afterat the time stepTime.

To specify the logic value parameters, the integer code has to be used.

Code Table

Logic value Integer code Meaning
'U' 1 Uninitialized
'X' 2 Forcing Unknown
'0' 3 Forcing 0
'1' 4 Forcing 1
'Z' 5 High Impedance
'W' 6 Weak Unknown
'L' 7 Weak 0
'H' 8 Weak 1
'-' 9 Do not care

If the logic values are imported by
import L = Digital.Interfaces.Logic;
they can be used to specify the parameter, e.g., L.'0' for forcing 0.
