+  The myHDL could be a layer in our OneClick environment:
+  
+     4 our Model (using lists, no clock, running on processes)
+     3 myHDL
+     2 our VHDL components, myHDL RTL
+     1 complete design in VHDL
+  
+  MyHDL can offer functionality that we also need:
+  
+  - hierarchy
+  - connecting components
+  - generics (in Python input/output port and generics are all method arguments,
+      the constant arguments become named constants in the generated VHDL)
+ 
+  For SA the myHDL could be the entry level. On top of myHDL for use the 
+  model could be the entry level.
