18 years agoI found what is going on:
Altera Q72 writes a continously filled sheet , with data like this : 1 00 01 02 032 04 05 06 07
3 08 09 10 11
4 12 13 14 15 ... as a hex file like this : :0400000001020304f2
:0400040005060708de
:0400080009101112b8 ... where the 0004, 0008 are obviously byte adresses, while ModelSim wnats to have word adresses. So there is a mismatch.:mad: This hex above shows up in Modesim like this : 0000000000 0009101112
0000000000 0000000000
0000000000 0005060708
0000000000 0000000000
0000000000 0001020304 which means reverted in order and only every 4th word written.:( What is the right interpretation of this intel HEX ?:confused: ------------------------ I stepped back to MIF and found that the same HEX file saved as a MIF runs right in Modelsim. It worked with ModelSIM SE 6.3c :cool: - I have no Idea why it failed with 61.g AE before.
