PCB Design for Suspension Emulator

I am developing an automotive electronics module whose purpose is to electronically emulate the factory suspension feedback system in a vehicle.

The module’s function is to reproduce the sensor feedback signals expected by the OEM controller so the vehicle continues to see a valid suspension state when the original dampers or related hardware are removed or replaced.

Scope of work:

* Design a compact automotive-grade PCB schematic and layout for this emulator.
* Implement the required signal generation and conditioning so the ECU receives the correct suspension feedback signals.
* Account for the expected signal characteristics, including voltage ranges, timing behavior, pull-ups/pull-downs, filtering, and protection.
* Select components that are suitable for automotive electrical noise, temperature, and vibration conditions.
* Prepare the design for manufacturing, including DFM review.

I will provide:

* Connector pinout for the suspension-related interfaces
* Measured waveforms / expected sensor behavior from the factory system
* Functional requirements for the signals that must be emulated

You will provide:

* Complete schematic
* PCB layout
* BOM with readily available components
* Gerbers
* Pick-and-place files
* Brief bench-test notes confirming the board outputs the required feedback signals when powered and stimulated as specified

Preferred experience:

* Automotive electronics
* Mixed-signal PCB design
* Signal conditioning / sensor emulation
* EMC-aware design for noisy vehicle environments
* CAN-bus familiarity is a plus, even though the main task is signal emulation rather than CAN modification

Important:
This is not a hobby or Arduino-style project. I need a design that is manufacturable and robust enough for automotive use.

Please respond with:

* Relevant past work
* Recommended CAD tool
* Estimated timeline
* Fixed-price quote
