Make a file = =E2=80=9Clepton.conf=E2=80=9D in the project directory, containing the = lines:

[netlist.hierarchy]

traverse-hierarchy=3D0

Long answer:

You=E2=80=99ve mixed spice-style and layout-style = hierarchy. Layout-style, with hierarchy traversal in the netlister using = source=3D, connects pinlabel to refdes by name using symbols with = device=3DINPUT or device=3DOUTPUT. Spice-style connects pinseq to = refdes, in lexical/numeric ordering (P10 after P9), using = device=3Dspice-IO . Spice-style is intended for separate netlisting of = subcircuits, while layout style flattens out the netlist.

Spice-style has a few problems:

1. The pinseq attribute is overloaded, used also = for slotting. This may cause conflicts.

2. The association of lexical/numerical ordering = of symbol refdes with pinseq is confusing and error-prone.

3. It=E2=80=99s incompatible with flattening = netlists for layout.

This is why I = made spice-noqsi work properly in layout-style without flattening = (traverse-hierarchy=3D0). You never need to use spice-style (although = you may) with spice-noqsi.

Changing the program names to the Lepton equivilents, all = works fine,
except the Spice file, schematic.cir, has only = the power supply on the

Well, that=E2=80=99s a complete, = complicated project. Can you strip it down into a simple test case to = ease debugging? Something like:
