Electronic circuit design tools.

Project description

buildstatus coverage


Electronic circuit design in Python 3.

  • IBIS parsing. Currently only a subset of the IBIS 6.1 specification is supported.

Project homepage:



pip install ecdtools

Example usage

In this example we load an IBS-file and access some of its content.

>>> from pprint import pprint
>>> import ecdtools
>>> ibs_file = ecdtools.ibis.load_file('tests/files/ibis/pybis/bushold.ibs')
>>> model = ibs_file.get_model_by_name('TOP_MODEL_BUS_HOLD')
>>> model.model_type
>>> pprint(model.gnd_clamp)
[('-2.0000e+00', '-6.158e+17', 'NA', 'NA'),
 ('-1.9000e+00', '-1.697e+16', 'NA', 'NA'),
 ('-1.8000e+00', '-4.679e+14', 'NA', 'NA'),
 ('-1.7000e+00', '-1.290e+13', 'NA', 'NA'),

 ('-1.5000e+00', '-9.802e+09', 'NA', 'NA'),
 ('-1.4000e+00', '-2.702e+08', 'NA', 'NA'),
 ('-1.3000e+00', '-7.449e+06', 'NA', 'NA'),
 ('-1.2000e+00', '-2.053e+05', 'NA', 'NA'),
 ('-1.1000e+00', '-5.660e+03', 'NA', 'NA'),
 ('-1.0000e+00', '-1.560e+02', 'NA', 'NA'),
 ('-9.0000e-01', '-4.308e+00', 'NA', 'NA'),
 ('-8.0000e-01', '-1.221e-01', 'NA', 'NA'),
 ('-7.0000e-01', '-4.315e-03', 'NA', 'NA'),
 ('-6.0000e-01', '-1.715e-04', 'NA', 'NA'),
 ('-5.0000e-01', '-4.959e-06', 'NA', 'NA'),
 ('-4.0000e-01', '-1.373e-07', 'NA', 'NA'),
 ('-3.0000e-01', '-4.075e-09', 'NA', 'NA'),
 ('-2.0000e-01', '-3.044e-10', 'NA', 'NA'),
 ('-1.0000e-01', '-1.030e-10', 'NA', 'NA'),
 ('0.', '0', 'NA', 'NA'),
 ('5', '0', 'NA', 'NA')]

Alternatively, with transform=True, the same input as above gives:

>>> from pprint import pprint
>>> import ecdtools
>>> ibs_file = ecdtools.ibis.load_file('tests/files/ibis/pybis/bushold.ibs',
>>> model = ibs_file.get_model_by_name('TOP_MODEL_BUS_HOLD')
>>> model.model_type
>>> pprint(model.gnd_clamp)
