Stereo DSP Amplifier
reduce the board size so all components can fit inside maybe I would suggest you go with 100x100
Thought for 24 sec
Got it — I’ll switch the board to 100 × 100 mm and redo placement for that smaller outline before routing.
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.
