Thanks Andy, sorry to post in the wrong forum. Those are the files I am having trouble getting to work. I get a Warning: can't find the initialization file spinit. Thanks Al

This group is not about ngspice.? To the extent that ngspice model requirements differ from LTspice, we can not help with those. Did you try looking at these? Files > z_groups.io > Lib > Digital

I wondered if anyone has seen a spice library for the CD14538B that will work in Kicad (ngspice). So far I haven't found one that works inside Kicad without spitting out errors. Thanks Al

It is kind of a "bummer" that Qorvo's QSPICE forum is like that.? New, first-time members there can't attach/upload their files.? On the one hand it makes some sense to stop new forum members from

All files in Temp are there temporarily.? Hence the directory name "Temp". That file is now found here: Files > z_yahoo > Examples > Educational Files > z_yahoo > Examples > Educational >

This has been asked before and I am just looking for the schematic: Files > Temp > Constant_phase_element1.asc Here's the old request and answer, Helmut did a great job but I can't find the schematic.

Thank you very much for your suggestion — you solved a problem that had troubled me for weeks. The convergence is indeed much better now. However, there are still some aspects of the model that

Try to implement the delay not using LC, but using RC. I replaced the voltage sources with an equivalent in the form of a controlled current source and an Rpar and Cpar connected to it.

Thanks for your efforts! I’ve seen the JA model you shared earlier—it’s excellent! However, the circuit I’m working on is the " inverse JA model", where *B* is the input and *H* is the output,

Hi. I managed to make a Jiles-Atherton model in LTspice. I also made a model taking into account the non-magnetic gap, and also derived H and B. I posted models on this forum. I also made the

Thank you Andy for your explanations. I will post results observed from other user for different LTspice versions as soon as possible. ---- Udo

Hi all, I’m implementing an inverse Jiles-Atherton model in LTspice, mainly based on this paper: https://ieeexplore.ieee.org/abstract/document/996206 The simulation stops around a quarter cycle. It

Hi Andy, When I updated Qspice to the latest version I was able to run the simulation example for UCC27282 sent to me from Qspice forum (not my own one but one uses half bridge only), so that drew me

Hi Andy, After I regenerated the model in Qspice and ticked the box that says include all the file, I stopped having this error: COMPHYS_BASIC_GEN I had the set of errors I mentioned on Q forum !,

Looks OK so far.? The value listed in the Help just has more digits (greater precision) than the values printed in the Error Log file.? It should be obvious why that happened. Do you have the

I saw that you had entirely different errors from QSPICE that you described in the QSPICE forum, than the ones you said you were having, in this group. I have to wonder, what's going on? Why did you

Suded, Another thing that I was thinking (but forgot to state here) was this: Since the problem seems to be that your QSPICE simulation was not picking up all the subcircuit definitions in TI's model,

Hi Andy, Tony I managed to run the schematic for synchronous buck boost converter (the same uploaded schematic) in Qspice after I updated it Many thanks for your help Best regards, Suded

Thank you Tony. Regards Udo
