6.1 Functions
The library contains the following function groups:
 Logical operators
 Mathematical operators
 Relational operators
 Bitshift operators
 Bit operators
6.1.1 Logical operators
 Conjunction (AND)
 Disjunction (OR)
 Negation (NOT)
 Exclusive OR (XOR)
The logical operators can operate with BOOL or INT variables.
If the input values are INT, the operation is bitwise performed and the output is also an
INT.
6.1.1.1 Conjunction (AND)
Fig. 6.1
The output Q is True if both inputs are True. The function AND represents a serial con-
nection in an electrical circuit.
