The shmem_fill procedure fills a block of BFM shared memory with a specified data pattern.
| Location | altrpcietb_g3bfm_shmem.v | |
|---|---|---|
| Syntax | shmem_fill(addr, mode, leng, init) | |
| Arguments | addr | BFM shared memory starting address for filling data. | 
| mode | Data pattern used for filling the data. Should be one of the constants defined in section Shared Memory Constants. | |
| leng | Length, in bytes, of data to fill. If the length is not a multiple of the incrementing data pattern width, then the last data pattern is truncated to fit. | |
| init | Initial data value used for incrementing data pattern modes. This argument is reg [63:0]. The necessary least significant bits are used for the data patterns that are smaller than 64 bits. | |
