Description

Creates placement, routing, or other obstructions based on the obstructionType argument. All conditions that are enforced for these obstructions through GUI-based flow are applicable here. For example, only one placement blockage is applied per soft block. If a second placement blockage is applied through this API, a warning is issued.

Arguments

g_cphId	ID of the physical configuration cellview
g_sbId	ID of the soft block
l_PhysLCV	List of ("lib" "cell" "view") triplets
t_obstructionType	Type of obstruction to be added. Valid values are: "placement", "routing", "fill", "slot", "pin", "feedthru", and "screen".
?topOffset n_topOffset
	Top offset of the obstruction
?bottomOffset n_BottomOffset
	Bottom offset of the obstruction
?leftOffset n_LeftOffset
	Left offset of the obstruction
?rightOffset n_RightOffset
	Right offset of the obstruction
?layerName t_layerName
	Layer name. This argument is ignored when the obstructionType is “placement”.

Value Returned

t	The obstruction was created.
nil	The command was unsuccessful.

Example

cphSbDefineObstruction(cphId sbId "routing" ?topOffset 10 ?bottomOffset 10 ?rightOffset 10 ?leftOffset 10 ?layerName "metal1")
