Smartwatch Design Concept

flux

You want to clean up the PCB layout of the Advanced Health Smartwatch project.
  • I created the Plan:
    1. Inspect congested layout regions
    2. Review the 8-layer stackup and layout rules
    3. Clean up overlapping/floating copper and reduce unrouted congestion
    4. Re-run DRC and iterate

Started implementing a plan

#Goal

- Clean up the PCB layout of the Advanced Health Smartwatch project by reducing congestion, eliminating overlapping and floating copper, ensuring consistent stackup and layout rules, and validating the board state.

#Implementation plan

1. Inspect the current PCB layout

1. Identify congested regions, focusing on areas with high airwire density, overlapping copper (15 instances), and floating copper (67 instances).

2. Mark critical areas that hinder routing and signal integrity.

2. Review and adjust the stackup and layout rules

1. Validate the changes made for the 8-layer board stackup.

2. Update layout rules to ensure uniformity and compliance with manufacturing constraints.

3. Clean up connectivity and copper regions

1. Eliminate overlapping copper issues by re-routing and consolidating copper regions.

2. Remove floating copper by connecting or removing unused copper islands in congested areas.

3. Optimize unrouted connectivity paths to relieve congestion in dense zones.

4. Validate board state

1. Re-run design rule checks (DRC) to ensure no new or pending issues.

2. Confirm that airwire count is reduced, overlapping copper is corrected, and floating copper is minimized.

3. Iterate as necessary until the board achieves a stable and cleaner state.

#Success criteria

- Airwire count is significantly reduced from 221

- All overlapping copper issues are resolved

- Floating copper is minimized or eliminated

- Consistency in the 8-layer stackup and layout rules, validated by DRC

- Overall board state is stable and manufacturable
