In QSYS I have an ADC, PLL and an Avalon-MM Read Master to access the internal ADC of the Altera Max10. The control and user interface of the Read Master are exported.

Now I struggle to setup the control interface to access the ADC channels. Mainly following signals:

  • control_fixed_location
  • control_read_base
  • control_read_length

The interface description of the Read Master is:

The block diagram for the Read Master is:

Questions:
- How do I need to set the control signals to access the ADC channel x?
- Where can I find the base address for the ADC implemented in QSYS?

Maybe someone can give me an example how to simulate this interface in ModelSim.

Thanks in advance!
