write_from_file
Initiate an AXI write transaction on one of the AXI-Master ports. The write data is used from the file. Burst type used is INCR. This is a blocking task and returns only after the completion of AXI WRITE transaction. Need to pass FILE_DATA_WIDTH_128 for accessing files with 128-bit data contents. If FILE_DATA_WIDTH_128 is passed, then the address must be 128-bit aligned. If FILE_DATA_WIDTH_128 is not passed, then the address must be 32-bit aligned. For
example: |
[1023:0] master_name: R5_API or A72_API. [1023:0] File_name: File name that stores the write data. [43:0] start_addr: write address [31:0] wr_size: number of bytes to be written For 32-bit file contents, wr_size should be in multiples of 4. For 128-bit file contents, wr_size should be in multiples of 16. |
[1:0] response: The slave write response from
the following: [OKAY, EXOKAY, SLVERR, DECERR] |
read_to_file
Initiate an AXI read transaction on one of the AXI-Master ports. The read data is written to a file. Burst type used is INCR. This is a blocking task and returns only after the completion of AXI READ transaction. Need to pass FILE_DATA_WIDTH_128 for accessing files with 128-bit data contents. If FILE_DATA_WIDTH_128 is passed, then the address must be 128-bit aligned. If FILE_DATA_WIDTH_128 is not passed, then the address must be 32-bit aligned. For
example: |
[1023:0] master_name: R5_API or A72_API. [1023:0] file_name: File name that stores the write data. [43:0] start_addr: write address [31:0] rd_size: number of bytes to be read. For 32-bit file contents, rd_size should be in multiples of 4. For 128-bit file contents, rd_size should be in multiples of 16. |
[1:0] response: The slave write response from
