I have a KiCAD 5.1 project that simulates fine. I’ve downloaded KiCAD 6.0.7, opened the project and when I try to simulate it I get a load of model errors.
Looking at one of the problem lines in the generated spice netlist I see:
Q552 Net-_C550-Pad1_ Net-_Q552-Pad2_ Net-_D501-Pad1_
If I go back to KiCAD 5.1 and look at the netlist there I see:
Q552 Net-_C550-Pad1_ Net-_Q552-Pad2_ Net-_D501-Pad1_ AUY21
so KiCAD 6 has stripped the model off of some of my parts. The schematic is large so this is not so easily fixed manually. The question is, what is happening? I have AUY21 defined in a text block on the schematic:
.model AUY21 PNP(Bf=75 Is=36u Re=0.04456 Vaf=48 Ise=480n Tf=530n Tr=10u)
and if I go to Q552 in KiCAD 6 and look at the properties then go to Spice Model it shows the model as ‘AUY21’ and ‘BJT’
How can I fix this? The UI settings look OK to me.
