GL85 synthesizable code

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!

Note that code uses, bit and logic_vector as data types.
You can convert these to std_logic, and std_logic_vector!

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...

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%
