EDB: geometry creation

This example shows how you can use EDB to create a layout.

Import EDB layout object

Import the EDB layout object and initialize it on version 2022 R2.

import time
import os
import pyaedt

start = time.time()

aedb_path = os.path.join(pyaedt.generate_unique_folder_name(), pyaedt.generate_unique_name("pcb") + ".aedb")
print(aedb_path)
edb = pyaedt.Edb(edbpath=aedb_path, edbversion="2022.2")

D:\Temp\pyaedt_prj_7PV\pcb_75YMCE.aedb

Add stackup layers

Add stackup layers.

if edb:
    edb.stackup.add_layer("GND")
    edb.stackup.add_layer("Diel", "GND", layer_type="dielectric", thickness="0.1mm", material="FR4_epoxy")
    edb.stackup.add_layer("TOP", "Diel", thickness="0.05mm")

Create signal net and ground planes

Create a signal net and ground planes.

if edb:
    points = [
        [0.0, 0],
        [100e-3, 0.0],
    ]
    edb.core_primitives.create_trace(points, "TOP", width=1e-3)
    points = [[0.0, 1e-3], [0.0, 10e-3], [100e-3, 10e-3], [100e-3, 1e-3], [0.0, 1e-3]]
    edb.core_primitives.create_polygon_from_points(points, "TOP")

    points = [[0.0, -1e-3], [0.0, -10e-3], [100e-3, -10e-3], [100e-3, -1e-3], [0.0, -1e-3]]
    edb.core_primitives.create_polygon_from_points(points, "TOP")

Create vias with parametric positions

Create vias with parametric positions.

if edb:
    edb.core_padstack.create_padstack("MyVia")
    edb.core_padstack.place_padstack([5e-3, 5e-3], "MyVia")
    edb.core_padstack.place_padstack([15e-3, 5e-3], "MyVia")
    edb.core_padstack.place_padstack([35e-3, 5e-3], "MyVia")
    edb.core_padstack.place_padstack([45e-3, 5e-3], "MyVia")
    edb.core_padstack.place_padstack([5e-3, -5e-3], "MyVia")
    edb.core_padstack.place_padstack([15e-3, -5e-3], "MyVia")
    edb.core_padstack.place_padstack([35e-3, -5e-3], "MyVia")
    edb.core_padstack.place_padstack([45e-3, -5e-3], "MyVia")

edb.core_nets.plot(None, color_by_net=True)

Save and close EDB

Save and close EDB.

if edb:
    edb.save_edb()
    edb.close_edb()
print("EDB saved correctly to {}. You can import in AEDT.".format(aedb_path))
end = time.time() - start
print(end)

EDB saved correctly to D:\Temp\pyaedt_prj_7PV\pcb_75YMCE.aedb. You can import in AEDT.
