Programming a Sensitivity Map Header File into a Memory
You can program a .smh into any type of memory. For example, to use CFI flash memory, follow these
steps:
1. Rename the
.smh to .hex , or convert it to little-endian .hex if required.
2. In the Quartus II software, click File > Convert Programming Files.
3. In the Convert Programming Files window under Output programming file, select the desired
options.
4. To add hex data, follow these steps:
Figure 13: Add Hex Data Dialog Box
a. Click Add Hex Data.
b. In the Add Hex Data dialog box, turn on Set start address and enter a start address.
c. In the Hex file box, click browse to select the .hex file, and click OK.
5. Click Generate.
Performing a Lookup for SMH Revision 1
To perform a lookup into the sensitivity map header data using a bit, byte, and frame number from an
EMR (Stratix IV devices only):
1. Read the 32-bit frame information string for the frame number:
• Address = 0x14 + (frame*4)
• Return value = (
frame_info_data_offset
,
offset_map_array_index
)
2. Read the offset map information for a frame. The return value for the offset map information is 16 bits:
• Address =
offset_map_base_address
+ offset array for current frame + offset data value for
current byte and bit
