+===== Goals =====
+  * Generate beautiful Cpp code from a KiCad schematic
+  * Compiles without dynamic memory allocation (embedded, savety)
+  * Read and write system states during runtime (e.g. with a simple terminal)
+  * Simple custom system creation (KiCad component editor + sub-class implementation)
+  * Hierarchical design (sub-systems)
+  * full documentation within the schematic
 ===== Mini-Demo =====

 It should be possible to combine a set of systems to a sub-system, where new inputs and outputs are defined.
-KiCads hierarchical schematic structure could be used out of the box, but in C++ we do not see anything from this. Similar to the KiCad PCB layout, which also doesn't know anything about a hierarchical sheets. Altium Designer has the so called rooms, which group and synchronize footprint arrangement and traces between multiple instances of one hierarchical sheet.

Altium Designer has the so called rooms, which group and synchronize footprint arrangement and traces between multiple instances of one hierarchical sheet.
 For the systems we should make something similar to the properties, which live in a SnsPropertyContainer. We should make a SnsSystemContainer, which provides on one hand memory for the different objects of a sub-system and on the other hand new inputs and outputs.
+==== Any-Type Inputs/Outputs ====
+Perhaps it would be useful, that not all inputs must have the same type. For example a mute gate, where the enable is bool and the signal is double.
+Pros:
+  * more flexible systems
+Cons:
+  * every pin must have a type specified in KiCad (could be done with net-annotators, similar to PWR_FLAG).
+  * we cannot use a simple template-interface class any more, such as the SnsHybrid or SnsNumeric.
+=== Proposal ===
+  * in cases, where this is really needed, a specific Cpp class could be implemented
+  * mixture of numbers and bool shouldn't be any problem
