[Qucs-help] Problem with SPICE Netlist in Qucs 0.0.18.130703. More information

[Jose M. C. <jos...@ho...>]

Hello:
Recently I have sent an e-mail, talking about a problem with the SPICE netlists in this new version of QUCS. I told you that the problem arose when I tried to simulate one circuit that I designed with the previous version 0.0.17.3 of QUCS. This design can be analysed in the 0.0.17.3 version with no problem.
When I start the simulation, in the window that always pops up informing about the process, says: "Creating netlist". And, at the same time, another window pops up (the label of this windows is "Information") saying "Converting SPICE file /media/ ... /NXP_BFR520.cir"In this second window there is only one option (one button in the window) for closing it: "Abort".
The simulation remains frozen waiting for this conversion. But no matter how long you wait, nothing happens.Eventually, when you are tired of waiting and you press "Abort" in the second window,  in the first one, in the text filed of "Errors and Warnings" appears this message:"/usr/local/bin/qucsator: error while loading shared libraries: libqucs.so.0: cannot open shared object file: No such file or directory"
After that I tried to determine if the problem was in the file. So I went into the netlist SPICE component where I had imported the spice netlist. I double clicked on the component and it appeared an error message window saying:
"/usr/local/bin/qucsconv: error while loading shared libraries: libqucs.so.0: cannot open shared object file: No such file or directory"
At this point, it was clear that something was happening with this file. I tried to find it, and I did it in the route: /usr/local/lib.Some time ago, I had a similar problem with other program, and the solution was to copy the file in /usr/local/lib to /usr/lib.
In fact, I copied all the "lib" files related to qucs in this folder. There were four files named "libqucs_something_" and I decided to copy all of them to /usr/lib.
After doing that, the situation has changed.  When I analyse the circuit containing the netlist SPICE component, the same two windows that I have mentioned before, pop up and the simulation stops like before. But when I press "abort" in the second window, in the "Errors and Warnings" field of the first window says:"line 65: syntax error, unexpected '.', expecting EndSub"
It seems that there is some error in the netlist that I am working with. The strangest thing of all of that stuff, is that the ".cir" file only has 54 lines ... I have counted them using the QUCS editor. You can see it by yourselves. The ".cir" file is the following.

Hi Jose,

Your spice model seems to work for me. Using 0.0.17.

A few comments in-line below.

I am wondering where did you get this version from.
The last stable release is 0.0.17, where does the extra .3 comes from?

How did you install Qucs? It seems that there are issues with the search 
path for libraries. Did you compile from source? Did you run `sudo 
ldconfig` and restarted?

> At this point, it was clear that something was happening with this file. I tried to find it, and I did it in the route: /usr/local/lib.Some time ago, I had a similar problem with other program, and the solution was to copy the file in /usr/local/lib to /usr/lib.

Copying libraries might help temporarily, but usually it creates more 
issues and do not solve the problem on its source.

> After doing that, the situation has changed.  When I analyse the circuit containing the netlist SPICE component, the same two windows that I have mentioned before, pop up and the simulation stops like before.

This error message is likely form the `netlist.txt` located on your 
`~/.qucs` directory. Not from the spice .cir file.

First of all, you can check whether `qucsator` is able to translate the 
spice file. Try:
`qucsconf -h`
`qucsconv -if spice -of qucs -i NXP_BFR520.cir`

As I said, it seems to work on my side.
Here is a small project with a DC and transient simulations:
https://www.dropbox.com/s/8gjed0ghk2hdwh2/spice_BFR520.qucs

You can find some instructions about using Spice and Qucs in here:
http://qucs.sourceforge.net/docs/tutorial/spicetoqucs.pdf

I think your Qucs installation is broken. I suggest you to cleanup and 
reinstall it.

Hi Jose,

Indeed the latest master is getting stuck as you described. I am looking 
into it.
For some reason I understood you had issues with 0.0.17...

Re: [Qucs-help] Problem with SPICE Netlist in Qucs 0.0.18.130703. More information

[Guilherme B. T. <gui...@gm...>]

Hi Jose,

There  was a bug. Sorry for the inconvenience.

We are updating Qucs... sometimes we also introduce bugs.
The code that invokes `qucsconv` was not able to read back its output. 
Creating a netlist with a blank in it... Hence the errors you saw.

Please either download a new repository snapshot [1] or clone the 
repository if you want to `git pull` fixes in the future [2].

Only `qucs` was modified. If you `cd qucs` and follow as you did 
already... it should work.

Please let me know if it works on your side.

Regards,
Guilherme

Re: [Qucs-help] Problem with SPICE Netlist in Qucs 0.0.18.130703. More information

[Guilherme B. T. <gui...@gm...>]

Hi Jose,

Thank you for reporting!

On Windows, depending on how you installed it might be necessary to add 
a QUCSDIR to your environment variables, or set it on the CMD console 
before launching Qucs from there. See 
http://sourceforge.net/p/qucs/bugs/140/

Regards,
Guilherme
