In revision 2 files, the sensitivity map header is an extension of revision 1 header format. The header
information provides basic information about the .smh revision 2, and includes all the revision 1 header
information fields. The additional fields include size of the sensitivity data tag size in bits, base addresses
for the region map, and 32-bit CRC signature of the corresponding .sof file.
The 32-bits ID of the sensitivity map header revision 2 is defined as follows:
• Bits 23:0—Altera sensitivity map header ID 0x445341
• Bits 24:31—a bit mask for the header information with bit 24 reserved
• Bit 25—indicates the presence of sensitivity tag information in the .smh
• Bits 27:26—reserved
• Bit 28—indicates the presence of 32-bit CRC signature of corresponding .sof
• Bits 29:31—reserved
