The lasted developments seem to be successful !

v2.6 is progressing and I can already list not only the gates but their interconnections !

 13x A3P gates found.
 no exclusion input file to read.

  ************ END OF NETLIST ************

This is the netlist extracted from the INC8 unit and it's getting better and better. It matches well with the schematic :

I'm polishing things and I should add a few things :

• histogram of the fanouts...
• find a way to activate/trigger a given LUT entry
• "compile" the "depth" and check for loops or disconnected stuff
• ...

---

The latest update has a few enhancements and the ALU8 passes the netlist extractor :-)
