System architecture
Assign functions to the board, firmware and connected application. Operator controls and actuator outputs may need separate boards, with a command interface between them.
Approach
New product development
From requirements to hardware and firmware.
Define the device's functions, physical constraints and connections before selecting components or developing the board and firmware.
Requirements and system development
- System requirements
- Component selection
- Hardware and firmware design
Establish the requirements before implementation
A project may begin with an enclosure, existing machine, preferred controller or required function. These inputs establish the interfaces, power requirements and physical limits. AUBRIX can develop them into a design brief, with the engineering stages and outputs agreed before implementation.
Component suitability
Compare electrical requirements, package size, firmware support and connector access. Review sourcing options and record alternatives that need approval; similar parts are not necessarily interchangeable.
Early verification priorities
Identify assumptions that could materially change the design. An interface check or placement review can resolve a critical requirement before detailed development continues.
Engineering process
Project
process.
- 01
Define functional requirements
Document intended use, inputs, outputs, available power and physical constraints. Separate essential functions from later features.
- 02
Assess architecture and components
Compare controller and communication options against the requirements. Resolve compatibility and sourcing questions before committing components to the layout.
- 03
Develop hardware and firmware
Prepare the agreed schematic, placement, routing or firmware foundation. Review connector positions, electrical interfaces and software responsibilities together.
- 04
Review readiness for prototyping
Record the revision, open questions and verification plan. Determine whether the design needs further review, a prototype build or a focused firmware test.
Depending on the agreed scope
Project
deliverables.
- Requirements and interface documentation
- An agreed schematic or PCB design package
- Component selections and reviewed alternatives
- A firmware outline and verification plan
Outputs are agreed for the assignment. Design files and assembly renders document a design; manufacturing, prototype bring-up and production release are separate stages.
