This is the wrong thread for open-source discussion!
Nonetheless, I think I’ve already made my position clear. The problem is that there’s nobody ready to help. Sad but true. If you think that’s not the case, please prove me wrong and get involved.
If not, maybe you are right, and I should create a commercial version. Then perhaps, I get some benefit out of the immense work on this project.
Concerning the authorship of the code, I published all GPL sources that contain work of other people on this website.
The most common functions are already available. So, if you think that very important ones are missing, please give a concrete example.
Because s-parameters are complex-valued, log10(…) gives a complex number, too. In rectangular diagrams, the magnitude is shown, which is always positive.
20*log10(abs(S[3,3])) is what you want.
Currently, the only possibility is to use the component name of the symbol. I.e. for the example above:
In the “model” field, replace the second token “SP” with “_15SQ47N_”.
Note that a component name must not begin with a digit, therefore the underscore at the beginning. And the schematic editor will append a number at the end in order to make the string unique, therefore the underscore at the end (for better readability).
Good luck!
Old versions are not available, because it’s strongly recommended to use the latest one. The only reason would be to convert files older than version 3, but this can be performed with the version 3.3.2-light that can still be downloaded.
What have you in mind?
Fine!
For other components, the keyword “capacitor” in the above-mentioned line can be replaced by “coil”, “BJT” or “FET”.
Yes, the symbol combobox is currently for SPICE subcircuits only. You should not use it for sNp files.
As a workaround, you can choose “edit” and in the “model” field append the following line:
“polar” 0 “linear” 0 “open” 0 “none” 0 “capacitor” 0
Note: The first character in the line above is a space!
In the main menu “Project” choose “Import Library…”, then select the files and enter a name for the new library. Finally, press “Convert” button.
That’s all, good luck!
