The hardware design phase is broken down into a high level and a low level phase. The high level phase involves creating a block diagram of the hardware problem. Each block or module can then be defined in more detail. This includes defining all the electrical interface requirements between modules which facilitates efficient parallelism in group design. Engineers can then focus on their respective modules. A peer review is recommended at the completion of the high level design phase.
High Level Deliverables include:
- Hardware High Level Design (HLD) documentation
- Preliminary Bill of Materials
The Low level design includes the creation of schematics, parts database, and PCB layout. Where required we insert a peer design review after the completion of the low level design documentation and schematics prior to PCB Layout. When we are not responsible for mechanical enclosure design, the printed circuit board (PCB) outline drawing, typically a DXF or DWG file supplied by the client, is used as the starting point for PCB layout.
Low Level Deliverables include:
- Hardware Low Level Design (LLD) documentation
- Schematics – Orcad Files
- Bill of Materials – Parts & Vendors Database
- PCB Design Database – Gerber Files, etc.
