+# Python Design Input
+
+A design can be given as a Python script instead of a netlist file. The script
+builds the design with the Naja Python API, the same API that
+[Python primitive files](python-primitives.md) use for technology cells. The
+mode is for netlists produced or transformed by a program: every module,
+instance, net and connection is created by calling the API.
+
+## Usage
+
+CLI flag: `-python` (or `-py`). YAML: `format: python` (or `py`). The mode
+works for LEC and SEC.
+
+```bash
+build/src/bin/kepler-formal -python -v sec \
+  --design1 <script...> --design2 <script...> \
+  --liberty <cells.lib> \
+  [--python_design1_top <top>] [--python_design2_top <top>]
+```
+
+```yaml
+format: python
+verification: lec
+input_paths:
+  - [design1/cells.py, design1/top.py]
+  - [design2/top.py]
+py_tech_files:
+  - ./my_primitives.py
+python_design1_top: top
+python_design2_top: top
+```
+
+## Script contract
+
+Each script defines `constructLibrary(lib)`. Kepler-formal calls it with the
+design library of one side, after the technology primitives are loaded. The
+scripts of a design run in the listed order against the same library, so a
+design may be split over several files.
+
+```python
+import naja
+
+
+def constructLibrary(lib):
+    inv = primitive(lib, "INV")
+    top = naja.SNLDesign.create(lib, "top")
+    a = naja.SNLScalarTerm.create(top, naja.SNLTerm.Direction.Input, "a")
+    y = naja.SNLScalarTerm.create(top, naja.SNLTerm.Direction.Output, "y")
+    net_a = naja.SNLScalarNet.create(top, "a")
+    net_y = naja.SNLScalarNet.create(top, "y")
+    a.setNet(net_a)
+    y.setNet(net_y)
+    gate = naja.SNLInstance.create(top, inv, "u_inv")
+    gate.getInstTerm(inv.getScalarTerm("A")).setNet(net_a)
+    gate.getInstTerm(inv.getScalarTerm("Y")).setNet(net_y)
+```
+
+Primitive cells come from `py_tech_files` or `--liberty`, as in every other
+mode. They live in the primitive libraries of the design's database. A Liberty
+library keeps the name declared in the file, so look a cell up in every
+primitive library rather than by library name:
+
+```python
+def primitive(lib, name):
+    for primitives in lib.getDB().getPrimitiveLibraries():
+        model = primitives.getSNLDesign(name)
+        if model is not None:
+            return model
+    raise RuntimeError("primitive %s was not loaded" % name)
+```
+
+## Top selection
+
+`python_design1_top` and `python_design2_top` name the top module of each
+design. Without them the top is the module that no other module instantiates.
+When several modules qualify, name the top explicitly; the run stops with
+`No top design was found` otherwise. A named top that the script did not
+create stops the run with an error.
+
+## Notes
+
+- The script's `print` output is only shown when written to `sys.stderr` or
+  flushed; a run that stops on an error does not flush Python's `stdout`.
+- `naja.so` must be importable, as for Python primitive files; see
+  [How `naja.so` is found](python-primitives.md#how-najaso-is-found).
+- The in-process `kepler_formal` Python API does not accept this format. It
+  borrows live NajaEDA designs instead; see [Python API](python-api.md).
