DEF Property Definitions

[PROPERTYDEFINITIONS
    [objectType propName propType [RANGE min max] [value | stringValue]
    ;] ...
END PROPERTYDEFINITIONS]

The objectType corresponds to one of the following:

DESIGN
COMPONENT
NET
SPECIALNET
GROUP
ROW
COMPONENTPIN
REGION

The propType corresponds to one of the following:

INTEGER
REAL
STRING

This constuct lists all properties used in the design. The information is obtained by collecting all properties on specific objects types in the design. The following table shows the correspondence between the OpenAccess object and DEF objectType:

OpenAccess object	DEF objectType
oaDesign	DESIGN
oaInst	COMPONENT
oaNet	NET, SPECIALNET
oaInstTerm	COMPONENTPIN
oaTerm	COMPONENTPIN
oaCluster	GROUP
oaCluster	REGION
oaRow	ROW

Properties used for storing DEF attributes in OpenAccess must be filtered so they do not appear in the DEF file. For API information, refer to the iterators in the appropriate DEF construct sections, and PROPERTIES.

Certain characters are illegal in DEF property names and property values. These are the quotation character ("), semicolon, and newline. If a DEF file uses the pound character (#) as a comment character, that character is also an illegal character in property names and values. If illegal characters are encountered in a property name or value, the name or value is silently ignored during translation.
