Hi.
When using vsim, I encountered the following error:
Error loading design Command exited with non-zero status 12
The issue was solved changing the init value in RAM16X1D declaration in mlite_pack for 0x0016 instead of 0x16!
Hope it helps!
Thank you for reporting the problem.
In mlite_pack.vhd I changed:
component RAM16X1D generic (INIT : bit_vector := X"0000"); ... component RAM32X1D generic (INIT : bit_vector := X"00000000");
