The source files for the Waveform Generator can be found under the waveform-generator repository.
The general idea is that various stimuli can be arbitrarily connected to different driver.
Currently the following blocks are implemented:
wfg_stim_sinewfg_stim_memwfg_drive_spiwfg_drive_patwfg_interconnectwfg_corewfg_subcoreThe base address of the user project is 0x30000000.
By adding an offset to this base address, the various peripherals can be configured.
For more information about the register entries please refer to the waveform-generator repository.
