Ingenious, thank you, will use.

I was close to understanding of address ranges.

It tells how the source parts of {.mem | .elf } are mapped to individual
BRAMs' locations. I have also installed FPGA editor, and can see x-y
locations now, it's funny it pulls some lib*.so libraries and the
resulting user interface is like Windows v3.xx.

The source is 32 bits x 512 words.
0x7ff = 2047 = 512 * 4 addresses

Size of prom.mem = 512*8 lines + 512 LF = 4608
