CfgNets

class pyedb.configuration.cfg_nets.CfgNets(pedb=None, signal_nets=None, power_nets=None, reference_nets=None)

Fluent builder for the nets configuration section.

Overview

Methods

set_parameters_to_edb	Write signal / power-ground net classifications into the open EDB design.
get_parameters_from_edb	Read net classifications from EDB.
to_dict	Serialize the in-memory net classification lists.
get	Return a CfgNet object for an existing net in the EDB layout.
add_signal_nets	Append signal net names, accepting str, CfgNet, or lists thereof.
add_power_ground_nets	Append power/ground net names, accepting str, CfgNet, or lists thereof.
add_reference_nets	Append reference net names, accepting str, CfgNet, or lists thereof.
apply	Apply net configuration on the layout.
get_data_from_db	Read net classifications from EDB.

Method detail

CfgNets.set_parameters_to_edb()

Write signal / power-ground net classifications into the open EDB design.

CfgNets.get_parameters_from_edb()

Read net classifications from EDB.

CfgNets.to_dict()

Serialize the in-memory net classification lists.

Unlike get_parameters_from_edb(), this method does not query the live EDB session and therefore preserves any pending changes made via add_power_ground_nets() / add_signal_nets() before set_parameters_to_edb() has been called.

Returns:

dict

Dictionary with "signal_nets" and "power_ground_nets" keys.

CfgNets.get(net_name: str)

Return a CfgNet object for an existing net in the EDB layout.

Parameters:

net_namestr

Net name to look up, e.g. "GND" or "CLK".

Returns:

CfgNet or False

A CfgNet instance bound to the live EDB session, or False if the net does not exist in EDB.

Raises:

KeyError

If no EDB session is attached.

Examples

>>> cfg = edb.configuration.create_config_builder()
>>> net = cfg.nets.get("GND")
>>> if net:
...     print(net.classification)  # 'power_ground'

CfgNets.add_signal_nets(nets)

Append signal net names, accepting str, CfgNet, or lists thereof.

Any net already present in power_nets or reference_nets is removed from those lists before being added here.

Parameters:

netsstr, CfgNet, or list of str/CfgNet

Net name(s) to classify as signal.

CfgNets.add_power_ground_nets(nets)

Append power/ground net names, accepting str, CfgNet, or lists thereof.

Any net already present in signal_nets or reference_nets is removed from those lists before being added here.

Parameters:

netsstr, CfgNet, or list of str/CfgNet

Net name(s) to classify as power/ground.

CfgNets.add_reference_nets(nets)

Append reference net names, accepting str, CfgNet, or lists thereof.

Any net already present in signal_nets or power_nets is removed from those lists before being added here.

Parameters:

netsstr, CfgNet, or list of str/CfgNet

Net name(s) to use as reference nets.

CfgNets.apply()

Apply net configuration on the layout.

CfgNets.get_data_from_db()

Read net classifications from EDB.

Classes

CfgNet

Represents a single net in the EDB layout with live session access.
