What passed
Portable Verilog-2001 RTL, 13 public Icarus Verilog test targets, archived Tang Primer 20K Dock OSS Gowin-compatible build evidence and JTAG programming evidence.
Engineering note
af-pdm-rx public release status: board-build-ready, not hardware-ready
Public release notes for af-pdm-rx: current maturity, passed verification gates and remaining hardware evidence blockers.
Release gate
Public status
The public release notes state that af-pdm-rx is currently board-build-ready.
What is still blocked
Measured pdm_clk_o, physical GPIO loopback observation and real PDM MEMS microphone evidence.
Why this matters
The site avoids “production-ready” or “hardware-ready” claims until the remaining hardware observations are attached publicly.
Interpretation
What a reviewer can conclude today
A reviewer can conclude that the public repo documents the architecture, the test path and a measured set of build artifacts. A reviewer cannot conclude that the published board target has fully measured microphone bring-up evidence yet.
