Hi, please forgive me if this is a dumb question. I am trying to use the file based voltage and current sources, and I am at a loss looking for the .dat file format explained. I tried with a space, comma, tab separated two column (time/value) file with no success. Can anyone help me? Thanks, Romano As an aside: has anyone developed/available a Jill-Atherton hysteresis model, similar to the verilog-a two-phase tranformer? -- La presente comunicación tiene carácter confidencial y es para el exclusivo uso del destinatario indicado en la misma.

Look at the .dat files in the qucs projects... Alternatively you can use CSV files... Hope this helps, Stefan. |

Ah, all right. I didn't suspect that changing extension would do the magic... I am trying to use the verilog-a interface to build a non-linear, hysteretis-capable transformer model. If you know that there is something similar available, please shout :-). As for the question: when (and not if) I'll have problem, should I write to this list or to the developers one?

Could you please send us pointer to reference and model used for the transformer? I believe it will be simpler to use C++ model. Some possible link (the domain is huge). It will be easier for you to use a spice like schematic. @article{brachtendorf1997mhp, title={{Macromodeling of hysteresis phenomena with SPICE}}, author={Brachtendorf, HG and Eck, C. and Laur, R.}, journal={Circuits and Systems II: Analog and Digital Signal Processing, IEEE Transactions on [see also Circuits and Systems II: Express Briefs, IEEE Transactions on]}, volume={44}, number={5}, pages={378--388}, year={1997} } @article{naidu1991tdm, title={{Time domain model for the ferromagnetic core, including the effects of hysteresis and eddy currents}}, author={Naidu, SR}, journal={Science, Measurement and Technology, IEE Proceedings-}, volume={138}, number={1}, pages={44--50}, year={1991} } article{thomas2006tds, title={{Time-domain simulation of nonlinear transformers displaying hysteresis}}, author={Thomas, DWP and Paul, J. and Ozgonenel, O. and Christopoulos, C.}, journal={Magnetics, IEEE Transactions on}, volume={42}, number={7}, pages={1820--1827}, year={2006} } @article{greene1988nmt, title={{Nonlinear modeling of transformers}}, author={Greene, JD and Gross, CA}, journal={Industry Applications, IEEE Transactions on}, volume={24}, number={3}, pages={434--438}, year={1988} } @article{pedra2004pcm, title={{PSPICE computer model of a nonlinear three-phase three-legged transformer}}, author={Pedra, J. and Sainz, L. and Corcoles, F. and Lopez, R. and Salichs, M.}, journal={Power Delivery, IEEE Transactions on}, volume={19}, number={1}, pages={200--207}, year={2004} } @article{chua1970lcm, title={{Lumped-circuit models for nonlinear inductors exhibiting hysteresis loops}}, author={Chua, L. and Stromsmoe, K.}, journal={Circuits and Systems, IEEE Transactions on}, volume={17}, number={4}, pages={564--574}, year={1970} } article{chan1991ntm, title={{Nonlinear transformer model for circuit simulation}}, author={Chan, JH and Vladimirescu, A. and Gao, X.C. and Liebmann, P. and Valainis, J.}, journal={Computer-Aided Design of Integrated Circuits and Systems, IEEE Transactions on}, volume={10}, number={4}, pages={476--482}, year={1991} } BTW could you please shut up the following disclamer.
