Description

The SPI driver for the serial DACs was tested successfully on the Arria10 board a few weeks ago.
A similar test setup with an internal NCO providing a low frequency test waveform was used to test
the slow DACs on the SOCMFC controller. After some initial confusion caused by the controller SDCARD
not being updated with the correct firmware file (llrf.rbf), some simulation was performed to verify
the SPI signals and finally all four channels were found to work correctly with a 40 kHz update rate.
