ADC Hard Block primitive

Hello,

Does anyone know where the documentation/HDL instantitiation templates for the ADC Hard Block is located? I want to configure and access the ADC directly without using the modular adc IP.

Thanks,

- Sam

    Have you tried contacting Altera via mysupport? often, specific questions get you through directly to the correct support people, who can either provide the docs or tell you how to drive it.

    Refer to figure 8 in the ADC Timing section of the <DELTED>.

    What you've instantiated there is essentially what results having configured the IP from the catalogue into 'Configuration 4: ADC Control Core Only'. Refer to section 2.2.1 "Altera Modular ADC IP Core Configuration Variants", in the same document.

    Cheers,

    Alex

    For some reason I am having a hard time replying with a quote...

    This isn't exactly correct. ADC Control Core Only does implement a FSM and FIFO to support the Avalon-ST command/control interface. I am really looking for information on the raw control signals to the ADC block.
