In OpenAccess, a DEF region is modeled by a cluster object associated with one to several cluster boundary objects, and each cluster boundary represents an area (pair of points) of the region. The numRegions value corresponds to the number of cluster objects representing a region in a design. A cluster object represents a region if it is associated with at least one clusterBoundary object.
The regionName is obtained using:
void oaCluster::getName(oaString &name) const
Each pair of points corresponds to the lower left and upper right points of the bounding box of a clusterBoundary for the cluster. All the clusterBoundary objects of the cluster must be taken into account.
oaCollection oaCluster::getBoundaries() const oaIter<oaClusterBoundary>::oaIter<oaClusterBoundary>(const oaBaseCollection &coll) oaClusterBoundary *oaIter<oaClusterBoundary>::getNext() void oaFig::getBBox(oaBox &bBox) const oaInt4 oaBox::left() const oaInt4 oaBox::bottom() const oaInt4 oaBox::right() const oaInt4 oaBox::top() const
The TYPE information is obtained using the following API:
oaClusterType oaCluster::getClusterType() const
The following table shows the correspondence between DEF TYPE and oaClusterType.
| DEF TYPE | oaClusterTypeEnum |
|---|---|
| FENCE | oacClusterTypeExclusive |
| GUIDE | oacClusterTypeSuggested |
| - | oacClusterTypeInclusive |
