Does an ACE plugin for the EVAL-AD7986FMCZ exist. I found the listed software (stand alone) but has too many limitations to be of much use.
Unfortunately there is no ACE plugin yet developed for the EVAL-AD7986FMCZ.
The AD4003 is a very similar product to the AD7986, being a differential, 18-bit, 2 MSPS SAR ADC. The AD4003 has better performance and comes in a smaller package size, but it does not have the internal voltage reference and reference buffer that comes in the AD7986.
The AD4003 evaluation board (EVAL-AD4003FMCZ) does have a supported ACE plugin. So if the AD4003 fits your needs, I would recommend evaluating it with the EVAL-AD4003FMCZ eval board and ACE plugin.
