MAX10 10M04 - Not enough logic elements to use the ADC block?

Hi - I'm new to FPGA programming. I'm using the MAX10 10M04SAE144I7G on a board I made. I've gotten as far as programming it to blink LEDs and read pushbuttons now I'm trying to read an analog signal...

    Hi,


    Try to set the bdf file adc4.bdf to other name.


    Thanks,

    Regards,

Hi,


The high LE consumptions is because of enabling the Debug Path in Modular ADC core. May check the tutorial video link provided which had been used about 4640 LEs far exceeded the limit of 4,032 LEs.

If disabling the Debug Path, the LE consumptions will be reduced to about 1k+


Thanks,

Regards,

Sheng

    Ok thanks. I just regenerated a new .bdf file without the debug path but now I'm having troubles compiling because of these messages:

    Error (12181): Top-level entity "adc4" is ambiguous
    Error (12180): Instance could be entity "adc4" in file adc4/synthesis/adc4.vhd compiled in library adc4
    Error (12180): Instance could be entity "adc4" in file adc4.bdf compiled in library work

    Error (12153): Can't elaborate top-level user hierarchy

    What file is supposed to be set to the Top- level entity?

    Thanks
