I took a few minutes to compare your net-list to the one I was using and noticed a few differences:
- Pin 13 of L4 and pin 13 of F4 should presumably be connected to VCC, these connections weren't shown on the schematics. Depending on how your simulator works leaving these unconnected might cause those chips to be held in reset. - I have pin 1 of D6 connected to /VRESET instead of VRESET. Don't remember how I came to this conclusion, but I specifically commented it as being an error in the schematics, so you might want to look into it.
