Achronix Speedster22i Configuration - Manual (Page 17)

UG033, December 18, 2013 17
3. 4x Flash: A 4x Flash (.flash4x_0-3) binary file supporting configuration from 4 flash
memory devices. This the same full flash memory binary as above, but split into 4
files intended for a x4 flash memory configuration. There are NO newline characters
in the files and is again completely binary.
4. CPU Mode: File formatted for CPU mode programming (.cpu). This contains the
entire bitstream organized as 9 bits per line. The MSB is the read/write bit (always 1
for write), and the other 8 bits are 8 bits of bitstream data per line.
5. In addition a raw hex (.hex) file generation option is provided. This contains
bitstream data in hexadecimal format with 32-bits of data per line (and no read/write
bit like the .cpu file).
