Detailed Description

Utilities for Chip Level Design.

The ChipTools class provides a small set of utilities to ease the managment of a complete chip following the Alliance top hierarchical structure.

Constructor & Destructor Documentation

ChipTools()

ChipTools

(

Cell *

cell

)

Create a ChipTool for cell.

Member Function Documentation

isChip()

bool isChip ( ) const

inline

Returns: true if the Cell is truly a top level design. If not, this object is useless and does nothing.

Referenced by ChipTools::ChipTools(), KatabaticEngine::createDetailedGrid(), and KatabaticEngine::isChip().

getCell()

Cell * getCell ( ) const

inline

Returns: The top-level design.

getCore()

Instance * getCore ( ) const

inline

Returns: The instance of the core, that is, the only instance that is not a pad...

getChipBb()

const Box & getChipBb ( ) const

inline

Returns: The chip complete bounding box, this *is* simply the Cell bounding box.

getLeftPadsBb()

const Box & getLeftPadsBb ( ) const

inline

Returns: The bounding box enclosing all the pads on the left side of the chip.

Remark: This box is computed from the chip bounding box and the pad height.

getRightPadsBb()

const Box & getRightPadsBb ( ) const

inline

Returns: The bounding box enclosing all the pads on the right side of the chip.

Remark: This box is computed from the chip bounding box and the pad height.

getTopPadsBb()

const Box & getTopPadsBb ( ) const

inline

Returns: The bounding box enclosing all the pads on the top side of the chip.

Remark: This box is computed from the chip bounding box and the pad height.

getBottomPadsBb()

const Box & getBottomPadsBb ( ) const

inline

Returns: The bounding box enclosing all the pads on the bottom side of the chip.

Remark: This box is computed from the chip bounding box and the pad height.

getCorona()

const Torus & getCorona ( ) const

inline

Returns: The torus (in term of manhanttan distance) enclosed between the pad area and the core area.

intersectVPads()

bool intersectVPads ( const Box &  box ) const

inline

Returns: true if box intersect either the left or right pad box.

References Box::intersect().

intersectHPads()

bool intersectHPads ( const Box &  box ) const

inline

Returns: true if box intersect either the top or bottom pad box.

References Box::intersect().
