This section describes the
Bartels User Language index variable types for the Layout data access (LAY).
L_ALTPLNAME - Layout Net List Alternate Part Package Type
The
L_ALTPLNAME index variable type provides access to the connection list part alternate physical library name list of the currently loaded layout. The structure definition of

index L_ALTPLNAME { // Alternate Phys. Lib. Name Index
string PLNAME; // Physical Library Name
};
L_ATTRIBUTE - Layout Net List Attribute
The
L_ATTRIBUTE index variable type provides access to the connection list part or net attributes of the currently loaded layout. The structure definition of
L_ATTRIBUTE is:
index L_ATTRIBUTE { // Attribute Index
string NAME; // Attribute Name

L_CNET - Layout Net List
The
