Gdstk

[joamatab]

ported basic functionality from gdspy to gdstk backend

from phidl import Device
from phidl import quickplot as qp  # Rename "quickplot()" to the easier "qp()"
import phidl.geometry as pg
import numpy as np

# Create a blank device (essentially an empty GDS cell with some special features)
D = Device("mydevice")

poly1 = D.add_polygon([(-8, 6, 7, 9), (-6, 8, 17, 5)], layer=0)

T = D << pg.text('Hello!')

C = pg.arc(radius=25, width=2, theta=45, layer=1)
c = D << C  # Add the arc we created

# R = pg.rectangle(size = [5,10], layer = 2)
# r = D << R


def waveguide(width=10, height=1, layer=0):
    WG = Device("waveguide")
    WG.add_polygon([(0, 0), (width, 0), (width, height), (0, height)], layer=layer)
    WG.add_port(name="wgport1", midpoint=[0, height / 2], width=height, orientation=180)
    WG.add_port(
        name="wgport2", midpoint=[width, height / 2], width=height, orientation=0
    )
    return WG


wg1 = D << waveguide(width=6, height=2.5, layer=1)
wg2 = D << waveguide(width=11, height=2.5, layer=2)
wg3 = D << waveguide(width=15, height=2.5, layer=3)

wg2.movey(10).rotate(10)
wg3.movey(20).rotate(15)
# print(D.references)

# text2 = D << T.flatten()
# text2.movex(-10)
# print(text2)
D.write_gds("temp.gds")
# D.write_oas("temp.oas")

import gdsfactory as gf
gf.show("temp.gds")
print("END OF FILE")

still some tests failing and some with Fatal Python error: Segmentation fault when running pytest
