Using Properties Structured Logic Design Properties
Frexp Property
This property is used to define frames. Frames provide you with the ability to
repeat or conditionally include a circuit in a schematic sheet. The number of
iterations, or the conditions determining inclusion or selection are controlled by
parameters assigned during design creation and evaluation, and make use of the
frame expression assigned as a value to the Frexp property. The frame expression
uses similar constructs to those used in high level programming languages.
All frames must have the Frexp property assigned to them with a valid Frexp
property value. The value assigned to the Frexp property must adhere to a specific
syntax which uses key words such as FOR, IF, CASE, OTHERWISE, DOWNTO,
and TO with the assignment, equality, and relational (:=, ==, !=, =)
characters. For example “FOR i := 1 TO 5” is correct, but “FOR i += 1 TO 5” is
not. The syntax for FOR, IF, CASE, and OTHERWISE frames is discussed next.
Function Block Properties
There are three properties used to define Function Blocks, as follows:
• FB_DEF is a string property used to identify an unconnected, Made FB
Definition.
• FB_NAME is a required string used to represent the name of an FB
Instance or FB Definition.
• FB_INST is an optional string used to represent the future instance name of
the FB Definition or FB Instance.
