So, I'm trying to design a 555 sawtooth oscillator. At my school, we have multisim, and it is so nice and easy to design a circuit and get it working. But, I'm poor, and the student version of multisim requires a serial number to keep it forever -- and I am not all about that noise. Because of that, I'm stuck with KiCad. I love it (since it's gnu and all that), but I also hate it.

I keep getting this error whenever I try to simulate the oscillator circuit:

Circuit: KiCad schematic
Error: unknown subckt: x v- 2 -100 -300 150 u 50 50 0 1 w
Error: there aren't any circuits loaded.
Warning - approaching max data size: current size =  761.742 MB, limit =  676.242 MB

It would be nice if it at least told me the net it was so confused about. I've tried digging through the models of all of my components to no avail. What on earth is causing this problem? And how on earth do I fix it?

 

Also try the Kicad forum maybe.
Is this the latest version?
Max.

Yep. It is the latest (stable) version.

 

If its just circuit simulator, try it on free LTspice.
Max.

If you start The .pro file the schematic is not direct visible.
you have to go to that sheet.

Does your emulator know that? ( the error tells me that it can't fined schematic)

Solution:
Copy the schematic to the main page
Delete the sub page.
The indicators are set to ? (R1 becomes R? and so on)

LTspice is likely closer to Multisim than Kicad in how it operates.
