To enable synthesis of FPGA/CPLD hardware, XST will assume that all necessary signals are present in the sensitivity list. Please note that the result of the synthesis may differ from the initial design specification. The missing signals are: <AS> "C:/Users/Matze/Amiga/Hardwarehacks/Zorro-LAN-IDE/Logic/LAN_IDE/LAN_IDE_CP.vhd" line 156: Size of operands are different : result is <false>.

Signal <DTACK_S> is never used or assigned. This unconnected signal will be trimmed during the optimization process. Signal <AS_D> is never used or assigned. This unconnected signal will be trimmed during the optimization process. The value init of the FF/Latch 0 hinder the constant cleaning in the block LAN_INT_ENABLE. You should achieve better results by setting this init to 0. The value init of the FF/Latch LAN_INT_ENABLE hinder the constant cleaning in the block LAN_IDE_CP. You should achieve better results by setting this init to 0.
