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...

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
