Static Public Methods

oaAreaBlockage * create (oaBlock *block, const oaPointArray &points, oaBlockObject *owner=NULL)

Detailed Description

An area blockage is a type of blockage representing an area. The shape of a blockage is described using an oaPointArray. Coincident and collinear points are illegal in the point array for an area blockage. For more information on coincident and collinear points, see oaPointArray::compress()

The area blockage is most commonly used to prevent standard cells from being placed within a certain area.

Member Function Documentation

oaAreaBlockage * oaAreaBlockage::create (  oaBlock *    block,
const oaPointArray &    points,
oaBlockObject *    owner = NULL
)  [static]
 

This is the constructor for an area blockage.

Parameters:
block The block in which to create the area blockage
points The pointArray describing the shape of the blockage
owner The optional owner of the blockage
Exceptions:
oacBlockageHasExtraPoints 
oacBlockageTooFewPoints 
oacInvalidBlockageOwner 

oaBoolean oaAreaBlockage::isSoft (    )  const
 

This function gets the boolean value for the soft attribute on this derived blockage.

void oaAreaBlockage::setPoints (  const oaPointArray &    points ) 
 

This function updates the shape of the blockages to the shape specified by the pointArray

Parameters:
points The pointArray describing the new shape of the blockage
Exceptions:
oacBlockageHasExtraPoints 
oacBlockageTooFewPoints 

void oaAreaBlockage::setSoft (  oaBoolean    soft ) 
 

This function sets the boolean value for the soft attribute on this derived blockage. If an oaAreaBlockage has the soft attribute set (true), standard cells are not placed within the blockage area during initial placement, though later optimization phases can use the blockage area.

Parameters:
soft A boolean that sets the soft attribute to true or false

void oaAreaBlockage::transform (  oaDouble    scale,
oaDouble    angle
) 
 

This function transforms this blockage by the specified scale factor and rotation angle. If this blockage is a leader in a group, every object in the group is moved with the specified transform.

Parameters:
scale The scale for the transformation
angle The angle of the transformation
