---|---|---|
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. |
