Edb

class pyedb.dotnet.edb.Edb(edbpath: str | None = None, cellname: str | None = None, isreadonly: bool = False, edbversion: str | None = None, isaedtowned: bool = False, oproject=None, student_version: bool = False, use_ppe: bool = False, technology_file: str | None = None, remove_existing_aedt: bool = False)

Provides the EDB application interface.

This module inherits all objects that belong to EDB.

Parameters:

edbpathstr, optional

Full path to the aedb folder. The variable can also contain the path to a layout to import. Allowed formats are BRD, MCM, XML (IPC2581), GDS, and DXF. The default is None. For GDS import, the Ansys control file (also XML) should have the same name as the GDS file. Only the file extension differs.

cellnamestr, optional

Name of the cell to select. The default is None.

isreadonlybool, optional

Whether to open EBD in read-only mode when it is owned by HFSS 3D Layout. The default is False.

edbversionstr, int, float, optional

Version of EDB to use. The default is None. Examples of input values are 232, 23.2, 2023.2, "2023.2".

isaedtownedbool, optional

Whether to launch EDB from HFSS 3D Layout. The default is False.

oprojectoptional

Reference to the AEDT project object.

student_versionbool, optional

Whether to open the AEDT student version. The default is False.

technology_filestr, optional

Full path to technology file to be converted to xml before importing or xml. Supported by GDS format only.

Examples

Create an Edb object and a new EDB cell.

>>> from pyedb.dotnet.edb import Edb
>>> app = Edb()

Add a new variable named “s1” to the Edb instance.

>>> app['s1'] = "0.25 mm"
>>> app['s1'].tofloat
>>> 0.00025
>>> app['s1'].tostring
>>> "0.25mm"

or add a new parameter with description:

>>> app['s2'] = ["20um", "Spacing between traces"]
>>> app['s2'].value
>>> 1.9999999999999998e-05
>>> app['s2'].description
>>> 'Spacing between traces'

Create an Edb object and open the specified project.

>>> app = Edb("myfile.aedb")

Create an Edb object from GDS and control files. The XML control file resides in the same directory as the GDS file: (myfile.xml).

>>> app = Edb("/path/to/file/myfile.gds")
