Examples

>>> from pyedb import Edb
>>> edb = Edb("myedb", edbversion="2026.1")
>>> edb_net = edb.nets["GND"]
>>> edb_net.name
'GND'

Method detail

classmethod Net.create(layout, name: str)

Create a new net in the EDB database.

Parameters:

layoutpyedb.grpc.database.layout.layout.Layout

Layout to create the net in.

namestr

Name of the new net.

Returns:

Net

Newly created net object.

Net.find_dc_short(fix=False) → list[list[str]]

Find DC-shorted nets connected to this net.

Parameters:

fixbool, optional

Whether to automatically rename nets to resolve shorts. Default: False (only report shorts).

Returns:

list[list[str]]

List of shorted net pairs in the format [[net_name1, net_name2], …].

Net.plot(layers=None, show_legend=True, save_plot=None, outline=None, size=(2000, 1000), show=True, title=None)

Plot the net using Matplotlib.

Parameters:

layersstr or list[str], optional

Layer name(s) to include. If None, uses all signal layers.

show_legendbool, optional

Enable legend display. Default: True.

save_plotstr, optional

Full path to save the plot image. If specified, overrides show.

outlinelist, optional

Outline points for plot boundary.

sizetuple, optional

Image dimensions in pixels (width, height). Default: (2000, 1000).

showbool, optional

Display the plot. Default: True.

titlestr, optional

Plot title. Uses net name if None. Default: None.

Net.get_smallest_trace_width() → float

Get the minimum trace width from path primitives in this net.

Returns:

float

Smallest width found in database units. Returns 1e10 if no paths exist.

Net.delete()

Delete the net from the EDB database.

classmethod Net.find_by_name(layout, name)

Find a net by name in a given layout.

Parameters:

layoutLayout

Layout to search for the net.

namestr

Name of net.

Returns:

Net

Net found. Check the is_null property of the returned net to see if it exists.
