PortGeometry

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.

Variables:

• name (str | None, optional) – Name of the port

• sourceName (str | None, optional) – Name of the port source

• destName (str | None, optional) – Name of the port destination

• type (PortType | None, optional) – Type of the port

• ioDirection (IO) – IO direction of the port.

• sideOfTile (Side) – Side of the tile the port’s wire is on.

• offset (int) – Offset to the connected port.

• wireDirection (Direction | None, optional) – Direction of the ports wire

• groupId (int) – ID of the port group.

• groupWires (int) – Number of wires in the port group.

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

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

• nextId (int) – ID of the next port in the group.

Methods

generateGeometry(name, sourceName, destName, portType, ioDirection, relX, relY) → None

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

saveToCSV(writer) → None

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

PortType

class PortType(*args, **kwds)

Bases: Enum

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
