Get PCell information

  • PCell = device

Get PCell name

  • name = device.name

Get PCell region

  • region = fp.get_bounding_box(device)

    • (min_x, min_y), (max_x, max_y) = fp.get_bounding_box(device)

Get ports information

  • Get the number of ports:

    • Get total number of ports: len(device.ports)

    • Get left ports: gpdk.port_util.get_left_ports(device)

    • Get right ports: gpdk.port_util.get_right_ports(device)

  • orientation: device[”op_0”].orientation

  • waveguide_type: device[”op_0”].waveguide_type

  • waveguide width: device[”op_0”].waveguide_type.core_width

  • position (x, y): device[”op_0”].position[0], device[”op_0”].position[1]

Get two points relative information

Here we would like to know some information e.g. distance, angle, between two points(points can be acquired by curve_points of a curve or the position of the ports)

  • Distance of the two points: fp.distance_between(pointA, pointB)

  • Middle point of the two points: fp.midpoint_between(pointA, pointB)

  • Angle between two points: fp.angle_between(pointA, pointB)

    • This function returns the radian of the angle.
