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.
I’ll inspect the project structure and BOM, then create a concise high-level Mermaid block diagram document with MPNs where available.
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.
Review diagram and ERC
Run schematic ERC
Fix ambiguous MPNs
Create power tree
Check BOM risk

ERC报告 — 按附录B分类
运行结果摘要
当前ERC主要为 Floating Pin 警告,来源于尚未完成端口/连接器符号补全及部分预期No-Connect处理项。
附录B预期警告处理
  • 单端网络 MB_INTERLOCK_IN / MB_INTERLOCK_OUT:按附录B标注为外部客户接线,不修改原理图拓扑。
  • J_OM0~J_OM2 悬空端:按附录B作为默认跳线状态处理,需No-ERC。
  • 独立电源域:PWR_5V、PWR_ENC_5V、ADC_5V_SENSOR、ADC_3V3_ADC保持独立,不混接。
  • SPI_MISO:应设为Bidirectional。
  • J5 DNP与未使用GPIO:应显式No-Connect或上下拉。
当前Flux ERC摘录
  • Floating Pin: U7:SW/BOOT/VCC/VIN/PG/EP/PGND/EN/FB
  • Floating Pin: U9/U10 全部差分接收相关引脚待连接DB25和MCU GPIO
  • Floating Pin: U18 A/B/Y/VCC/GND 待连接Interlock与Laser Gate
  • Floating Pin: U19~U22 光耦隔离通道待连接J_IO和MCU/扩展IO
  • Floating Pin: U3/U5 MCP23017端口待连接I2C、地址、IO与上下拉
结论
附录B定义的预期ERC项目已分类记录;当前项目仍需要补齐连接器符号与剩余CONNECT语句后再次运行ERC,才能得到可交付的干净ERC报告。
