The following constants are defined in altrpcietb_g3bfm_shmem.v. They select a data pattern for the shmem_fill and shmem_chk_ok routines. These shared memory constants are all Verilog HDL type integer.
| Constant | Description | 
|---|---|
| SHMEM_FILL_ZEROS | Specifies a data pattern of all zeros. | 
| SHMEM_FILL_BYTE_INC | Specifies a data pattern of incrementing 8-bit bytes (0x00, 0x01, 0x02, etc.). | 
| SHMEM_FILL_WORD_INC | Specifies a data pattern of incrementing 16-bit words (0x0000, 0x0001, 0x0002, etc.). | 
| SHMEM_FILL_DWORD_INC | Specifies a data pattern of incrementing 32-bit DWORDs (0x00000000, 0x00000001, 0x00000002, etc.). | 
| SHMEM_FILL_QWORD_INC | Specifies a data pattern of incrementing 64-bit qwords (0x0000000000000000, 0x0000000000000001, 0x0000000000000002, etc.). | 
| SHMEM_FILL_ONE | Specifies a data pattern of all ones. |
