prBoundary Attributes

Attribute	Modify	Type	Description
include Generic Boundary Attributes.
blockages	no	l_objId	List of blockages associated with the prBoundary.
coreBoxSpec	yes	list	List the coreBoxSpec of the boundary. See example below.
IOBox	yes	list	IO box of the boundary. See example below.
isOrthogonal	no	boolean	Indicates if the blockage is orthogonal. When t, the blockage is orthogonal.
isRectangle	no	boolean	Indicates if the blockage is rectangular. When t, the blockage is a rectangle.
objType	no	string	Type of object "PRBoundary".

Example:

prBoundaryId~>coreBoxSpec

=> l_coreBoxSpec / nil

prBoundaryId~>coreBoxSpec = l_coreBoxSpec

=> t / nil

The coreBoxSpec is a list of the following format:

coreBoxSpec = list(l_bBox g_isHorizontal f_rowSpacing
           t_spacingType t_flipType g_siteDef)

g_siteDef = d_siteDefId | t_siteDefName

When retrieving the coreBoxSpec from a prBoundary, if the siteDef of the coreBoxSpec is bound, an ID will be return, otherwise, a name will be returned. When setting the coreBoxSpec, either a name or an ID is accepted.

prBoundaryId~>IOBox 
=> l_bBox / nil

prBoundaryId~>IOBox = l_bBox 
=> t / nil

prBoundaryId~>blockages

=> l_blockageId / nil
