Hi, VHDL friends Does anyone have a synthesizable gl85, or i8085 VHDL design? I have them, but can't synthesize with leonardo or synopsis. Please reply to this address. Thank you a lot!

the original from hamburg vhdl is probably not fully working at least there is one modified version that claims severl problems beeing fixed
this modified version synthesis OK, see below:
----------- Writing NGDBUILD log file "i8085_c.bld"... NGDBUILD done. Completed process "Translate". Started process "Map".
Using target part "2vp7ff672-6". Removing unused or disabled logic... Running cover... Running directed packing... Running delay-based LUT packing... Running related packing...
Design Summary: Number of errors: 0 Number of warnings: 1 Logic Utilization: Number of Slice Flip Flops: 317 out of 9,856 3% Number of 4 input LUTs: 3,614 out of 9,856 36% Logic Distribution: Number of occupied Slices: 1,876 out of 4,928 38% Number of Slices containing only related logic: 1,876 out of 1,876 100% Number of Slices containing unrelated logic: 0 out of 1,876 0% *See NOTES below for an explanation of the effects of unrelated logic Total Number 4 input LUTs: 3,622 out of 9,856 36% Number used as logic: 3,614 Number used as a route-thru: 8
Number of bonded IOBs: 45 out of 396 11% IOB Flip Flops: 18 Number of GCLKs: 3 out of 16 18%
Total equivalent gate count for design: 25,801 Additional JTAG gate count for IOBs: 2,160
