FABulous.geometry_generator.fabric_geometry¶

Classes for generating and managing the geometry of FPGA fabrics.

Classes¶

class FabricGeometry(fabric, padding=8)[source]¶

Fetch and hold geometric information about a fabric.

Objects of this class can be constructed by passing a Fabric object and optionally, padding.

Creates the fabric geometry by processing the given fabric definition and automatically generating the complete geometric layout.

Parameters:

fabric (Fabric) – The fabric object from CSV definition files
padding (int, optional) – Padding used throughout the geometry, by default 8

fabric[source]¶

The fabric object passed from the CSV definition files

Type:: Fabric

tileNames[source]¶

Set of unique tileNames in the fabric

Type:: set[str]

tileGeomMap[source]¶

Map of the geometry of each tile by name

Type:: dict[str, TileGeometry]

tileLocs[source]¶

Locations of all tiles in the fabric

Type:: list[list[Location]]

padding[source]¶

Padding used throughout the geometry, in multiples of the width between wires

Type:: int

width[source]¶

Width of the fabric

Type:: int

height[source]¶

Height of the fabric

Type:: int

Methods:

genNeighbourConstraints(queried)[source]¶

Generate neighbour constraints for a given tile geometry.

Parameters:: queried (TileGeometry) – The tile geometry to generate constraints for
Return type:: None

generateGeometry()[source]¶

Generate the geometric information from the given fabric object.

The border attribute is set for tiles that are located at a border of the tile. This is done to ensure no stair-like wires being generated for these tiles. The distinction left/right and top/bottom is made, to prevent generation of horizontal and vertical stair-like wires respectively.

Return type:: None

saveToCSV(fileName)[source]¶

Save geometric information of the given fabric for the graphical frontend.

Parameters:: fileName (str) – The name of the csv file
Return type:: None

totalWireLines()[source]¶

Return the total amount of lines (segments) of wires of the fabrics routing.

Can, for instance, be used to initialize the size of datastructures in the frontend.

Return type:: int
