Using the CLB to SPI interface, without the CPU intervention, CLB will be able to send out a continuous stream of 16-bit data to SPI which then be saved in the device memory using the FIFO and DMA mechanism of the SPI. In order to ensure that the data from CLB is reaching to SPI and then to device memory, it is recommended for the software to implement tests to read back the SPI FIFO contents as well as to read back the final Memory contents and ensure that they are same.
