+- Successfully parse the wiring information from `ses` file to array
+  - A little "hacky" way, not using any parsing package
+  - Stands for `ses` file only
+- 
+### 08/05/2019
 
 - Working on parsing routed (wiring section) text information.
     - Ref: [pyparsing](https://scipy-cookbook.readthedocs.io/items/Reading_Custom_Text_Files_with_Pyparsing.html)
 - Parsing generated `dsn` file back to `DSN` class 
   - Fail
 - Parsing generated `kicad_pcb` file back to `pykicad` package - `pcb` class
+  - Success
+- Working on:
+  - debug dsn library so it can read file.
+  - `pykicad` uses `pyparsing` internally
+  - Rebuild `ses` file schema. Not working well
