Analyzing net connections and necessary checks.
- Duplicate/split nets by name
- Dwin_Uart_Arduino appears three times as separate net entries with different subsets of connections. This fragments a single logical signal into disjoint nets and masks ERC. Unify to one net.
- AC_HOT_IN is listed twice with different subsets of connections. Unify to one net.
- Q2_GATE_DRV and Q1_GATE_DRV each exist twice, one instance having connections and a second empty instance. Remove the empty net labels to avoid ambiguity.
- GND exists as two separate net entries (one has only U9). Ensure there is exactly one GND net and that all ground symbols connect to it.
- Single‑pin/floating nets
- Q4_A2 contains only Q4. This is a single‑pin net; the main triac’s A2 is not connected to any load or connector in the current netlist. Connect Q4 to the intended output/harness net (e.g., the same way Q3 ties into BLOWER2_HOT_OUT).
- UART_TX connects only to R1. This is a single‑pin net. Route UART_TX to its destination (MCU/header) or remove the dangling label.
- These align with ERC: “Single Pin Nets” has 2 errors; fix by completing or removing these nets.
- Same‑net short across two pins of a component (via split net entries)
- Connector pin shorts
- Optotriac LED current limiting present
- Triac gate resistors present
- Decoupling/bulk on +5V present
- ESD/surge protection present
- TVS array U9 is connected between the Dwin_Uart_Arduino net and GND (two pins labeled “~” are used on both nets). This is consistent with a 2‑line TVS arrangement. No issue observed in the schematic.
- Net typing and properties
- Dwin_Uart_Arduino is tagged as Net Type: +5V in multiple entries. This is a signal, not a power net. Change its Net Type to a signal class (e.g., Low Speed) and remove any incorrect voltage property.
- AC_NEUTRAL and AC_HOT_IN are Power nets, which is appropriate. Ensure voltage properties are set for power nets so ERC recognizes them consistently.
- UART line topology
- As wired, R1 is a 33 Ω series element from UART_TX into Dwin_Uart_Arduino, which is fine.
- R2 is entirely inside Dwin_Uart_Arduino (both pads end up on the same net after unifying duplicates), so it provides no series isolation and effectively shorts itself. Move R2 so one side is on the board’s UART_RX line and the other on the HMI RX pin net (after you split J4:PIN_3 and PIN_4).
- Do not tie J4 and J4 together; separate them into UART_TX and UART_RX nets, each with its own series resistor (R1 and R2).
- Triac channel completeness
- Net consistency and clarity
- Eliminate duplicate net labels and empty nets (the redundant Q1_GATE_DRV, Q2_GATE_DRV, fragmented Dwin_Uart_Arduino, AC_HOT_IN, GND). Keep one net object per name to avoid ERC blind spots and ensure correct connectivity across sections.
- Use clear, distinct UART net names (e.g., UART_TX, UART_RX) instead of one shared “Dwin_Uart_Arduino” for both pins. This prevents accidental shorts and improves readability.
- Power net metadata
- For +5V and AC nets, set Net Type to Power and add the voltage property. This helps ERC/DRC correctly classify power pins and flags missing power sooner.
- Unify split nets:
- Merge all Dwin_Uart_Arduino segments into one net; then split into two nets as appropriate for TX/RX. Reconnect R1 to UART_TX and rewire R2 in series on UART_RX.
- Merge AC_HOT_IN into a single net.
- Merge GND into a single net and ensure all ground symbols, including U9, are on that same net.
- Remove the empty duplicates of Q1_GATE_DRV and Q2_GATE_DRV.
- Fix connector shorts:
- Complete triac output:
- Connect Q4 to the intended load/harness net; do not leave A2 floating.
- Correct net typing:
- Change Dwin_Uart_Arduino (and the new UART_TX/UART_RX) Net Type to Low Speed/Signal (not +5V). Verify +5V and AC nets have Net Type = Power and a voltage property.
- Input LED current limiting for U1/U2/U3/U4 present with R13–R16.
- Triac gate series resistors R17–R20 present.
- +5V rail decoupling and bulk (C1, C2, C3, C4, C17, C18, C19) look complete for the present scope.
- TVS protection U9 provided on the HMI UART line.
- ERC reports 2 Single Pin Nets errors, consistent with Q4_A2 and UART_TX observations.
- DRC shows many layout issues (airwires, overlapping copper, floating copper), which are layout‑stage problems. They don’t change the schematic findings above, but will need resolution during PCB work.

Constructing a targeted plan.
- Unify duplicate nets and remove empty ones.
- Split UART into UART_TX/UART_RX, keep R1 on TX, move R2 to RX, keep U9 across both, assign J4 pins accordingly.

- Normalize net properties.
- Run ERC and report.
Started implementing a plan
#Goal
- Prepare targeted schematic edits to fix net and connectivity issues including unifying duplicate nets, separating and rewiring UART connections with series resistors and TVS protection, and updating the triac channel connection. Then run an Electrical Rules Check (ERC) to verify the changes.
#Implementation plan
1. Unify and clean net definitions:
1. Identify and merge duplicated nets (Dwin_Uart_Arduino, AC_HOT_IN, GND).
2. Remove empty duplicate nets for Q1_GATE_DRV and Q2_GATE_DRV.
2. Rewire UART signals:
1. Separate the unified UART net into two distinct nets, UART_TX and UART_RX.
2. Connect J4:PIN_3 to UART_TX and J4:PIN_4 to UART_RX.
3. Maintain R1 in series with UART_TX and R2 in series with UART_RX.
4. Connect TVS U9 across both UART_RX and UART_TX lines.
3. Complete the triac channel connection:
1. Connect Q4:A2 to the intended harness/output net ensuring it matches naming of other channels.
4. Normalize net properties:
1. Set UART_TX and UART_RX nets to the signal net class.
2. Ensure power nets (+5V and AC_HOT_IN) are correctly typed as power nets with proper voltage annotations.
5. Run ERC:
1. Execute the ERC on the updated schematic.
2. Review and report any remaining ERC issues.
#Success criteria
- All duplicate and empty nets are merged or removed accordingly.
- UART TX and RX signals are properly separated, connected, and include series resistors and TVS protection as required.
- Q4:A2 is correctly connected to the designated harness/output net.
- Net properties are normalized for both signal and power nets.
- ERC passes or clearly identifies any remaining issues for further refinement.
