Port geometry definitions.

Classes

class PortGeometry

A data structure representing the geometry of a Port.

Sets all attributes to default values: None for names and directions, zero for numeric values, and appropriate defaults for enumerated types.

name

Name of the port

Type:

str | None, optional

sourceName

Name of the port source

Type:

str | None, optional

destName

Name of the port destination

Type:

str | None, optional

type

Type of the port

Type:

PortType | None, optional

ioDirection

IO direction of the port.

Type:

IO

sideOfTile

Side of the tile the port’s wire is on.

Type:

Side

offset

Offset to the connected port.

Type:

int

wireDirection

Direction of the ports wire

Type:

Direction | None, optional

groupId

ID of the port group.

Type:

int

groupWires

Number of wires in the port group.

Type:

int

relX

X coordinate of the port, relative to its parent (bel, switch matrix).

Type:

int

relY

Y coordinate of the port, relative to its parent (bel, switch matrix).

Type:

int

nextId

ID of the next port in the group.

Type:

int

Methods:

generateGeometry(name, sourceName, destName, portType, ioDirection, relX, relY)

Generate the geometry for a port.

Sets the basic geometric and connection properties of the port, including its name, source/destination connections, type, I/O direction, and relative position within its parent component.

Parameters:

• name (str) – Name of the port

• sourceName (str) – Name of the port source

• destName (str) – Name of the port destination

• portType (PortType) – Type of the port (SWITCH_MATRIX, JUMP, or BEL)

• ioDirection (IO) – I/O direction of the port (INPUT, OUTPUT, or INOUT)

• relX (int) – X coordinate relative to the parent component

• relY (int) – Y coordinate relative to the parent component

Return type:

None

saveToCSV(writer)

Save port geometry data to CSV format.

Writes the port geometry information including type, name, source/destination connections, I/O direction, and relative position to a CSV file using the provided writer.

Parameters:

writer (object) – The CSV writer object to use for output

Return type:

None

class PortType(*args, **kwds)

Bases:

Enumeration for different types of ports in the fabric geometry.

Defines the various categories of ports that can exist within the fabric: - SWITCH_MATRIX: Ports connected to switch matrices - JUMP: Jump ports for long-distance connections - BEL: Ports connected to Basic Elements of Logic
