EDB: geometry creation

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

Final expected project

---

Import EDB layout object

Import the EDB layout object and initialize it on version 2023 R2.

---

import os
import time

import pyedb
from pyedb.generic.general_methods import (
    generate_unique_folder_name,
    generate_unique_name,
)

start = time.time()

aedb_path = os.path.join(generate_unique_folder_name(), generate_unique_name("pcb") + ".aedb")
edb = pyedb.Edb()
edb.save_edb_as(aedb_path)

True

Add stackup layers

Add stackup layers. A stackup can be created layer by layer or imported from a csv file or xml file.

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")

Material 'copper' does not exist in material library. Intempt to create it from syslib.
Material 'FR4_epoxy' does not exist in material library. Intempt to create it from syslib.

Create signal net and ground planes

Create a signal net and ground planes.

points = [
    [0.0, 0],
    [100e-3, 0.0],
]
edb.modeler.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.modeler.create_polygon(points, "TOP")

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

Create vias with parametric positions

Create vias with parametric positions.

edb.padstacks.create("MyVia")
edb.padstacks.place([5e-3, 5e-3], "MyVia")
edb.padstacks.place([15e-3, 5e-3], "MyVia")
edb.padstacks.place([35e-3, 5e-3], "MyVia")
edb.padstacks.place([45e-3, 5e-3], "MyVia")
edb.padstacks.place([5e-3, -5e-3], "MyVia")
edb.padstacks.place([15e-3, -5e-3], "MyVia")
edb.padstacks.place([35e-3, -5e-3], "MyVia")
edb.padstacks.place([45e-3, -5e-3], "MyVia")

<pyedb.dotnet.edb_core.edb_data.padstacks_data.EDBPadstackInstance object at 0x00000169A9BA40A0>

Geometry Plot

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

Stackup Plot

edb.stackup.plot(plot_definitions="MyVia")

<module 'matplotlib.pyplot' from 'C:\\actions-runner\\_work\\pyedb\\pyedb\\.venv\\lib\\site-packages\\matplotlib\\pyplot.py'>

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 C:\Users\ansys\AppData\Local\Temp\pyedb_prj_I24\pcb_Y34HDA.aedb. You can import in AEDT.
