Stereo DSP Amplifier

Worked for 13 mins 30 sec

I’m blocked because your account has no available ACUs, so AI execution tools are unavailable and I can’t continue routing or running final checks right now.

Accomplished so far:

Applied the uploaded BOM MPNs/footprint fields to the project properties as provided.
Changed the PCB from 200 × 200 mm to 100 × 100 mm, 4-layer stackup with Layer 2 as ground and Layer 3 as power.
Re-placed all 141 components on the 100 × 100 mm board with functional separation: analog inputs left, ESP32 top edge, Class-D/output stage right, power/regulators bottom/right.
Placement is mostly cleaned up, but 3 decoupling-loop warnings remained after the last placement pass: C14, C26, C33.

Open items:

Route every net.
Resolve remaining placement/DRC warnings.
Run final ERC/DRC.
Confirm whether the custom footprint names from the spreadsheet are accepted by manufacturing/export, since some were set exactly but reported as non-standard property values.

Suggested next steps once ACUs are available:

Fix C14/C26/C33 placement warnings.
Run pre-route board check.
Auto-route the board.
Run final ERC/DRC and clean remaining issues.
