High-Level Block Diagram Creation

R

rodgerliu

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

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

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.

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.

ERC记录 — DCDC外围处理完成
本轮目标
处理上轮剩余DCDC相关ERC：14个Floating Pin Warning + 3个Missing Power Error。
已完成的Schematic修改
  • 为 U_DCDC_5V、U_DCDC_3V3、U7 增加VCC旁路电容：
    • C_VCC_5V：U_DCDC_5V:VCC → ADC_5V_VCC_BYPASS，电容另一端 → GND
    • C_VCC_3V3：U_DCDC_3V3:VCC → ADC_3V3_VCC_BYPASS，电容另一端 → GND
    • C_VCC_U7：U7:VCC → PWR_5V_VCC_BYPASS，电容另一端 → GND
  • 为 U7 增加BOOT/SW基础外围：
    • C_BOOT_U7 between PWR_5V_BOOT and PWR_5V_SW
    • U7:BOOT → PWR_5V_BOOT
    • U7:SW + L1:P1 → PWR_5V_SW
    • L1:P2 → PWR_3V3
    • U7:EN → PWR_VIN
    • U7:FB → PWR_5V_FB named review net
  • 为 U6 / LM5013DDAR 建立剩余审查网络：
    • U6:BST → LM5013_BST
    • U6:SW → LM5013_SW
    • U6:FB → LM5013_FB
    • U6:RON → LM5013_RON
    • U6:EN/UVLO → PWR_VIN
ERC结果
  • 全项目ERC复跑：未返回 ERROR / WARNING / OPEN 项。
  • M40、RP2350、电源入口和DCDC相关ERC目前均已清理到工具未报告问题状态。
注意事项
  • LM5013_* 和 PWR_5V_FB 是保留给后续datasheet精确外围/分压/频率设定审查的命名网络。
  • 本轮只修改Schematic；未做Layout、Placement或Routing。
下一步建议
  1. 导出真正的Schematic PDF前，先抽查9个Sheet的层次/Section标注。
  2. 生成最终ERC报告文档。
  3. 只导出Schematic PDF和可编辑源文件，避免PCB分层图导出。
