What resistor are you using? There are two types of resistors in Qucs-S. Blue resistor is Qucs device and spaces are allowed in the resistance value for it. The red...

It is a limitation of the Ngspice. The `SIN` and `PULSE` sources are defined as vectors. And variables are not allowed inside the vectors. Also related to #53

> Do the other engines have this constraint? Yes, all SPICE engines (XYCE, SpiceOpus) define these sources as vectors. > Which engine do you think is the best? The Ngspice...

Yes, the MOSFET library was inherited from Qucs and the behavior will be the same. It seems that the default symbol in the library is wrong.

I performed a more investigations on this issue. The default symbol in the library is correct and usual MOSFET is also affected. The origin of this issue is related to...

Left panel uses pre-rendered PNG icons and therefore doesn't depend on Qt scaling. The symbol outline is rendered using line width=1 while dragging. The final symbol view uses thick lines...

I cannot say why the SPICE MOSFET symbols (dark red) were designed as depletion mode MOSFET. Probably it was simpler to draw one line instead of three lines. Concerning the...

I decided to correct the MOSFET symbols in one of the next versions. I have added this issue to the GUI improvements list #92 but classified it as low priority,...

@jleitch2013 I cannot find this source type in the Xyce manual. Could you please point where should I look for its description?

@tomhajjar Yes, I will consider a way how to add units like 1k, 1M, etc. for X-axis. The slight modification of the diagram properties will be required.
