eda-netlist-parser 0.1.1

A pure-Python parser for SPICE, Spectre, CDL, and DSPF netlist files — extracts subcircuit, port, device, and parasitic data for EDA automation and library characterization workflows

eda-netlist-parser

A pure-Python parser for SPICE-family netlist files: .spi, .cir, .cdl, .scs, .spf, .sp, .hsp.

Installation

pip install eda-netlist-parser
# optional colored terminal output:
pip install eda-netlist-parser[color]

Quick start

from netlist_parser import NetlistParser, NetlistError

parser = NetlistParser()

try:
    netlist = parser.parse("design.spi")
except NetlistError as e:
    print(f"Error: {e}")

for cell in netlist.cells:
    print(cell.name, cell.ports)
    for inst in cell.instances:
        print("  ", inst.name, inst.code, inst.device_name)

Importing

from netlist_parser import NetlistParser
from netlist_parser import NetlistParser, Netlist, NetlistCell, DeviceInstance

API

NetlistParser(internal=False)

Method	Returns	Description
parse(filename)	Netlist	Parse a single file
read(path, data=None)	varies	Parse file or directory

read() data modes:

data=	Returns
None	Netlist
'cells'	Set[str]
'ports'	Dict[str, List[str]]
'devices'	Dict[str, Set[str]]
'device-params'	Dict[str, Dict]
'resistors'	Dict[str, List]
'capacitors'	Dict[str, List]

Classes

• Netlist — full file data: .cells, .version, .resistance, .capacitance, .layer_map
• NetlistCell — one subckt: .name, .ports, .instances, .substitute
• DeviceInstance — one line: .name, .code, .nodes, .device_name, .number, .parameters
• NetlistError — raised on file errors

CLI

netlist-parser sample.spi                   # summary
netlist-parser sample.spi --cells           # list cell names
netlist-parser sample.spi --ports           # cell → ports
netlist-parser sample.spi --devices         # cell → device names
netlist-parser sample.spi --cell inv_x1     # one cell detail
