Circuit: netlist to schematic import

This example shows how you can import netlist data into a circuit design. HSPICE files are fully supported. Mentor files are partially supported.

Perform required imports

Perform required imports and set paths.

import os

import pyaedt

netlist = pyaedt.downloads.download_netlist()

project_name = pyaedt.generate_unique_project_name()
print(project_name)

D:\Temp\pyaedt_prj_R84\Project_X73.aedt

Set AEDT version

Set AEDT version.

aedt_version = "2024.1"

Set non-graphical mode

Set non-graphical mode. You can set non_graphical either to True or False. The Boolean parameter NewThread defines whether to create a new instance of AEDT or try to connect to an existing instance of it.

non_graphical = False
NewThread = True

Launch AEDT with Circuit

Launch AEDT with Circuit. The pyaedt.Desktop class initializes AEDT and starts it on the specified version in the specified graphical mode.

desktop = pyaedt.launch_desktop(aedt_version, non_graphical, NewThread)
aedtapp = pyaedt.Circuit(projectname=project_name)

Define variable

Define a design variable by using a $ prefix.

aedtapp["Voltage"] = "5"

Create schematic from netlist file

Create a schematic from a netlist file. The create_schematic_from_netlist method reads the netlist file and parses it. All components are parsed but only these categories are mapped: R, L, C, Q, U, J, V, and I.

aedtapp.create_schematic_from_netlist(netlist)
