Subcircuit name conflicts

[tomhajjar]

I have a Subcircuit conflict issue that is my fault. I know you always tell me to not use the same name for a Subcircuit schematic as the Spice model but ngspice normally just flags it with a warning. You always say to rename the .SUBCKT in the model. This is not practical in large Spice libraries and if making a Qucs-S library, the subcircuit schematic name should be how you want it to appear in the Library like "AD822" not "AD822x".

1. Holger pointed out the Subcircuit name conflicts in the netlists I sent him. Holger points to two solutions in the link below. I made "x" versions and and the simulations worked.

2. My question is couldn't Qucs-S use Subcircuit names that don't cause conflicts? I assume the "fatal" issue was I used Spice library instead of Spice netlist. Normally ngspice would flag a warning,

3. I had some projects fail because I tried to extract a complicated Spice model and all it's subcircuits from a large Library, edit them and make a new individual Spice model that works in Spice netlist. I hope using Spice library instead will solve some of my issues.

4. You mentioned in SPICE Library device limitation #944 that Spice Library device might get updated to allow making Qucs-S Libraries. This would ease making new Digital Libraries.
