+- Finish up path-finding approach (Approach B)
 - Only draw the best path on `dxf` when solution is found for every route.
 - ![circuit_dxf](journal_media/dxf_circuit.png)
 - Throw warning once a route cannot be found
 - ![fail_solution](journal_media/path_fail.gif)
+
+- Research on Approach A
+  - KiCAD 5 does not have built-in auto-router
+    - Have to use `FreeRouting`
+
+  - `FreeRouting` does not have python API
+  - Parent package of `FreeRouting`, `LayoutEditor` has multiple editions
+    - Part of `LayoutEditor` is open- source
+    - A large amount of of its website are broken, source and interface are unavailable
+
+- Other auto-routers are not open-source
+
+##### Approach A
+- 1. Use `LayoutEditor` python API to use `FreeRouting`
+- 2. Use `KiCAD 5` python API to sue `FreeRouting` 
+- 3. Use `KiCAD 4` python API to use builtin auto-routing
+
+- TODO:
+  - If can run KiCAD 4 from python
+  - Check `FreeRouting` API, see if a acceptable file can be generated from things on hand
