FO 10:32 PM Feature #85: 720p support/1080i support

Checked on the ram block input/output when built with 32KB and 64KB.
Same input, same mif, different output...
Check the output of ram_block_1a0 vs the input (myNextOpCode[1-7] and nextOpcInfo[42])
With block shared:

Tried to upgrade from Quartus 18.0 to 19.1. Same issue. foft

FO 10:28 PM Feature #85: 720p support/1080i support

Problem is with E8:
002020100112
bit 20 == high = opcStackUp.
This isn't what is in the constant table, so not clear why quartus is returning that.
Combined with 32KB, so no overlap I see:
002020000112
Where does that bit er... foft

Its opcodeInfoTable that is getting put into altsyncram. Not sure why its invalid yet. I'm trying the ramstyle attribute but didn't find the right voodoo yet... foft

with 32k, the block is not shared. I guess something is accessing memory where it shouldn't... foft

On v1 its all working, with 32K block ram as system ram. Once I put it to 64K block ram as system ram (which JUST fits) I never get to basic. After some playing with the logic analyzer (tricky, no block ram!) I can see that at C4F1 the C... foft
