Detailed Description

This class provides the basic placement interface, such as cells and pads position manipulation.

Constructor & Destructor Documentation

ophidian::placement::placement::placement	(	netlist::netlist *	netlist,
		library *	lib
	)

Placement constructor. Initializes the placement cell properties, such as positions and geometries.

Parameters

netlist	Circuit netlist.
lib	Placement library.

Member Function Documentation

geometry::multi_polygon<geometry::polygon<geometry::point<double> > > ophidian::placement::placement::cell_geometry ( entity_system::entity  cell ) const

inline

Returns the geometry of a cell as a multi polygon. Each polygon in the multi polygon represents a rectangle of the cell.

Parameters

cell	Cell to get the geometry.

Returns

Multi polygon with the cell geometry.

void ophidian::placement::placement::cell_position	(	entity_system::entity	cell,
		geometry::point< double >	position
	)

Changes the position of a cell.

Parameters

cell	Cell to move.
position	Target position of the cell.

geometry::point<double> ophidian::placement::placement::cell_position ( entity_system::entity  cell ) const

inline

Returns the position of a cell.

Parameters

cell	Cell to get the position.

Returns

Point describing the cell position.

const library& ophidian::placement::placement::lib ( ) const

inline

Returns the placement library used in the placement construction.

Returns

Constant reference to the library object.

const netlist::netlist& ophidian::placement::placement::netlist ( ) const

inline

Returns the netlist used in the placement construction.

Returns

Constant reference to the netlist object.

void ophidian::placement::placement::pad_position	(	entity_system::entity	pad,
		geometry::point< double >	position
	)

Changes the position of a pad.

Parameters

pad	Pad to move.
position	Target position of the pad.

geometry::point<double> ophidian::placement::placement::pin_position ( entity_system::entity  pin ) const

inline

Returns the position of a pin, calculated from the cell position and the pin offset.

Parameters

pin	Pin to get the position.

Returns

Point describing the pin position.
