# Goal

- Develop a working schematic and PCB layout for a CNC hydraulic press brake controller. The design must integrate the existing major components (STM32H743ZIT6, ADS1256IDBT, AD598JRZ for LVDT interfaces, ISO1I811TXUMA1 isolation chips, DAC8501E, RJ45, 24V input and other field connectors) with proper connectivity, safety (E-stop) and power structures, and ensure compliance with the fixed board dimensions and 4-layer stackup.

# Implementation plan

1. Define and lock system requirements and safety boundaries

1. Document net group assignments, isolation zones, fail-safe states, and E-stop behaviors in the project description.

2. Set the design constraints for separation between high voltage/power and sensitive analog amplifiers (ADC, DAC, and LVDT interfaces).

2. Complete schematic connectivity among all functional blocks

1. Connect the MCU (U1 - STM32H743ZIT6) to the ADC (U2 - ADS1256IDBT) and to the DAC modules (U8-U12 - DAC8501E) ensuring proper enable/reset signals.

2. Integrate the LVDT interface hardware (U3-U5 - AD598JRZ) by connecting scale inputs and calibration/signal conditioning circuits.

3. Connect the isolation modules (U6-U7 - ISO1I811TXUMA1) to the Ethernet (RJ45 J1) and other risk-prone interfaces.

4. Interconnect the 24V input (J2) and additional field connectors with the corresponding power and digital safety circuits.

3. Implement power, safety, and control structures

1. Integrate the 5-channel valve outputs and 8 digital inputs with proper safety and grounding considerations.

2. Ensure that E-stop and other safety signals are routed with redundant paths and shielding.

3. Validate signal integrity across analog (5ch +/-10V), digital, and power domains.

4. Define the PCB architecture and board constraints

1. Configure the layout to a 220 mm x 160 mm board with a 1.6 mm thickness and a 4-layer stackup (L1 and L4 as signal, L2 as solid GND, L3 as power).

2. Establish PCB zones for high-speed Ethernet, analog, and safety-critical nets with appropriate grounding, shielding, and edge keepout (1.0 mm) along with defined connector placement, including edge-mounted RJ45 and field connectors.

3. Assign and locate 4 x M4 plated holes inset 10 mm from the board corners for mounting.

5. Validate design and prepare for production transition

1. Run ERC and DRC checks to ensure that all schematic connectivity and PCB layout constraints meet the design objectives.

2. Resolve any errors or gaps in requirements to ensure safety, signal integrity, and manufacturability.

3. Update project documentation with all changes and notable design decisions.

# Success criteria

- All existing key components are correctly connected and interfaced, including MCU, ADC, DACs, LVDT interfaces, isolation, and power/safety structures.

- The schematic’s connectivity meets the CNC hydraulic press brake controller requirements with clearly defined signal, analog, and safety nets.

- The PCB layout conforms to the given dimensions, stackup, edge keepout, and connector placement constraints, with critical zones dedicated to safety and high-speed interfaces.

- ERC and DRC validations pass without critical errors, and design documentation is complete for transition to board manufacturing.

Updated to: "CNC hydraulic press brake controller with STM32H743, ADS1256, 5x DAC8501 ±10V outputs, 3x AD598 LVDT interfaces, isolated 24V digital inputs, 100BASE-TX Ethernet, watchdog, E-stop hardware disable, and 4-layer 220mm x 160mm PCB architecture. Domains: field 24V I/O, precision analog, logic/Ethernet. Safety behavior: E-stop and valve-disable force all analog command outputs to 0V-safe state and disable field enables; watchdog and power-good supervisor reset MCU on comms or rail faults. PCB constraints: L1/L4 signal+components, L2 solid GND, L3 power plane, 1.0mm board inset margin, RJ45 at edge, field connectors on opposite edge, isolation corridor between field wiring and logic/Ethernet, 4x M4 plated mounting holes inset 10mm from corners."
