pacman.model.constraints.placer_constraints package¶

Module contents¶

class pacman.model.constraints.placer_constraints.AbstractPlacerConstraint¶

A constraint on placement

class pacman.model.constraints.placer_constraints.BoardConstraint(board_address)¶

A constraint on the board on which a placement is made.

Parameters:	board_address (str) – The IP address of the Ethernet of the board to be used

board_address¶

The board of the constraint

Return type:	str

class pacman.model.constraints.placer_constraints.ChipAndCoreConstraint(x, y, p=None)¶

A constraint to place a vertex on a specific chip and, optionally, a specific core on that chip.

Parameters:	x (int) – the x-coordinate of the chip y (int) – the y-coordinate of the chip p (int or None) – the processor (if any) of the chip

location¶

Return type:	dict(str, int)

p¶

The processor on the chip, or None if that is not constrained

Return type:	int or None

x¶

The x-coordinate of the chip

Return type:	int

y¶

The y-coordinate of the chip

Return type:	int

class pacman.model.constraints.placer_constraints.RadialPlacementFromChipConstraint(x, y)¶

A constraint that attempts to place a vertex as close to a chip as possible (including on it).

Parameters:	x (int) – the x-coordinate of the chip y (int) – the y-coordinate of the chip

x¶

Return type:	int

y¶

Return type:	int

class pacman.model.constraints.placer_constraints.SameChipAsConstraint(vertex)¶

Indicates that a vertex should be placed on the same chip as another vertex.

Parameters:	vertex (AbstractVertex) – The vertex to place on the same chip

vertex¶

The vertex to place on the same chip

Return type:	AbstractVertex
