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 <file_name>.hex, or convert it to little-endian <file_name>.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

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
