Determining resource use for the ADAU1701

It's been awhile, but I've used the ADAU1701 for a few projects and thought I had an intuitive feel for how close a design came to maxing-out the chip's resources.  A new design, which looks as if it should run just fine, is putting out white noise with just a trace of the input signal audible.  When I start pulling out components, the noise lessens and finally disappears.

Other Sigma chips populate the 'Output' file, telling exactly how much overhead margin a project has.  I may have known how to derive this information for the 1701 at one time, but don't recall, and can't find it readily here on the forum.  Can someone point me in the right direction?  Many thanks!
