High-Level Block Diagram Creation

Create a high level mermaid block diagram of this project. Include key component's manufacturer part number in each block whenever possible.

Thought for 4 sec

flux

I’ll inspect the project structure and BOM, then create a concise high-level Mermaid block diagram document with MPNs where available.

Thought for 1 min 27 sec

flux

I found the major blocks: RP2350 MCU, power tree, M40 interface, XY2/encoder DB25, laser safety, I2C expanders, isolated digital I/O, and analog ADS8688-LZM8688 interface. I’m saving the diagram as a project document now.

Worked for 23 sec

flux

Created the high-level Mermaid block diagram and saved it in High Level Block Diagram. It includes the main functional blocks and key MPNs from the schematic/BOM, with caveats for connector-only or ambiguous regulator entries.

Review diagram and ERC

Run schematic ERC

Fix ambiguous MPNs

Create power tree

Check BOM risk

ERC记录 — RP2350与电源入口处理

本轮完成

全项目ERC初始剩余约116项，主要集中在U1、U3/U5、Sheet 1电源入口、DCDC外围和接口未用脚。
RP2350B：
- IOVDD/QSPI_IOVDD/USB_OTP_VDD/VREG_VIN/VREG_AVDD/ADC_AVDD → PWR_3V3。
- GND/VREG_PGND → GND。
- DVDD建立 RP2350_DVDD_1V1 命名网络。
- VREG_LX/VREG_FB建立 RP2350_VREG_LX / RP2350_VREG_FB 命名网络，等待按RP2350参考设计补电感/反馈/旁路。
- 未实现USB、SWD、晶振及未分配GPIO按No-Connect处理。
Sheet 1电源入口：
- 建立 PWR_RAW_IN、PWR_IDEAL_DIODE_GATE、PWR_IDEAL_DIODE_VCAP。
- F1、Q1、U8按LM74700+N-MOS理想二极管保护基础拓扑连接。
- U8 NC脚标No-Connect。
附录B式未用项处理：
- U3/U5未用MCP23017 GPIO/INT脚标No-Connect。
- U9/U10未用差分接收器通道标No-Connect。
- DB9未定义脚标No-Connect。
- M40 OM跳线未用脚标No-Connect。
- PG/PGOOD未用状态脚标No-Connect。

当前ERC摘要

剩余：14个Floating Pin Warning + 3个Missing Power Error。
剩余集中在DCDC外围：
- U_DCDC_3V3:VCC
- U_DCDC_5V:VCC
- U7:VCC
- U6:BST/FB/RON/SW/EN/UVLO
- U7:SW/BOOT/EN/FB
- L1:P1/P2

未决原因

DCDC的VCC/BST/BOOT/FB/RON/SW等脚需要严格按各芯片datasheet和原始附录A电源拓扑补外围电感、电容、电阻。
本轮未把DCDC VCC偏置脚强行接到PWR_3V3/PWR_5V，以避免把内部偏置/旁路脚错误接电源轨。

后续建议

查询TPS561201DDCR、LMR33630BDDAR以及U7对应芯片datasheet。
补DCDC VCC旁路电容、BOOT电容、电感、FB分压、EN/UVLO/RON网络。
再跑全项目ERC。

边界

本轮只修改Schematic。
未做Layout、Placement或Routing。
