Digital Output Analysis (dout)
===============================

The ``dout`` module provides tools for analyzing digital ADC outputs and bit-weighted architectures.

Bit And Weight Analysis
-----------------------

``analyze_weight_radix`` returns ``radix``, ``wgtsca``, and ``effres``.
``effres`` is computed from the significant absolute weights as
``log2(sum(abs_w_sig) / min(abs_w_sig) + 1)``. It is a theoretical
weight-list span, not a missing-code, DNL, INL, or SAR reachability proof.
