Modelica.Electrical.Digital.Converters

Converters between 2-,3-,4- and 9-valued logic

Information

The Converter BooleanToLogic, LogicToBoolean, RealToLogic, and LogicTo Real components are not standard logic components. They were designed to easily convert from or to Boolean or Real valued signals. The LogicToX01, LogicToX01Z and LogicTo UX01 converters correspond to standard logic functions. They transform 9-valued logic to 3- or 4-valued logic.

Extends from Modelica.Icons.Package (Icon for standard packages).

Modelica.Electrical.Digital.Converters.LogicToX01

Conversion to X01

Information

Conversion of a nine valued digital input into a X01 digital output without any delay according to IEEE 1164 To_X01 function.

Conversion Table:

input                  output
'U' (coded by 1)       'X'  (coded by 2)
'X' (coded by 2)       'X'  (coded by 2)
'0' (coded by 3)       '0'  (coded by 3)
'1' (coded by 4)       '1'  (coded by 4)
'Z' (coded by 5)       'X'  (coded by 2)
'W' (coded by 6)       'X'  (coded by 2)

'H' (coded by 8)       '1'  (coded by 4)
'-' (coded by 9)       'X'  (coded by 2)

If the signal width is greater than 1 this conversion is done for each signal.
