Hello Rakesh,
I would like to ask you whether you can update gnucap package from the 0.35 stable to the latest snapshots please ? Sure, this should first hit testing repositories. The latest snapshot contains a lot of enhancement for true mixed-mode simulation. Since Al Davis (upstream) is working behind systemc implementation on these snapshots, it will help us evaluate whether we can either spend it is worth to spend some time behind either
sampalib - https://fedorahosted.org/fedora-electronic-lab/ticket/34 systemcass - https://fedorahosted.org/fedora-electronic-lab/ticket/37
knowing the fact that we can't package systemc for fedora due to licensing issues.
Kind regards, Chitlesh
FYI, I played around with gnucap snapshots some time ago: http://sailer.fedorapeople.org/gnucap36-20090813-1.fc11.src.rpm This package should be parallel-installable to gnucap.
Unfortunately I wasn't able to get netlists with bsim transistor models to work. Seems like spice input isn't too reliable...

Send a mail to Al Davis to report this issue. He would be pleased to have some feedbacks. Since he is working on so many backends, some part could be broken. Please report this to him so that they can be fixed early.

Thanks Chitlesh, I will pick it up in a day or two. But, are you bit of sure that snapshots are stable enough to be pushed in rawhide.
I would surely push it in rawhide and sort of test it a bit, before planning for stable. In case you can confirm that it is stable enough in rawhide then in a week or so we can push it to testing.

Thanks,

I haven't yet tested these gnucap snapshots. However Al Davis is regularly releasing gnucap snapshots. So if we feed him with our feedbacks, I think he will be pleased to get them fixed. But if it breaks gcompris then we shouldn't update it.
I would suggest that you create some scratch builds and put them into your FASusername.fedorapeople.org for the time being and notify the FEL's mailing list when you update your private builds. Hence we can test them.

The reason why I want to get these gnucap snapshots is because we have 7 standard cell libraries (more than 300MB) (pharosc) which needs to be re-characterised, especially those of 0.13µm. Upstream is using "winspice" to characterise them since some features on gnucap or ngspice are still missing for such advanced characterisations.
Kind regards, Chitlesh

The main problem IMO is that the "user interface" (read the command language) has changed significantly, to the point that pretty much none of my netlists that worked with 0.35 work anymore. And I have not real idea how to fix this, because documentation and examples are scarce.

I put the current snapshot source RPM onto: http://sailer.fedorapeople.org/gnucap36-20091110-1.fc12.src.rpm
Only the source RPM though due to space limitations.

Can you elaborate? I have characterized a couple of commercial libraries by now using an ngspice CVS snapshot between rework19 and rework20, and now with your rework20 package. Earlier versions indeed had some limitations (missing .measure features) that made characterizing advanced flops impossible, but then again pharosc doesn't have any advanced flops.

If your netlists are opensource, can you place a copy on our FEL git repo please ? It will serve a testing. Little by little we are setting up a testing suite which we can use to ensure that the EDA softwares are working on the Livedvd. https://fedorahosted.org/fedora-electronic-lab/wiki/developers#UsingFELgitre...

Indeed the .measure features were missing. Do you want to co-maintain ngspice with me ? But if you are pulling some features from CVS, other users will have the same issues.
As for pharosc, I had to strip winspice and other binaries from the sources. I don't know about what exactly. However GrahamPetley sometimes talk about them. If you need more information, it's better to start another thread with him in CC: so that we can track every missing feature.
