1. Scope
Something like “This specification covers the electrical and mechanical requirements of the {product}. The {product} is/provides/consists of {brief description}.” A system block diagram is included as Figure 1.
2. References
Reference applicable standards and component specifications that are not appended. Other internal standards are often referenced.
3. Requirements
3.1. Operations Concise descriptions of each section is included as appropriate to the design. TBA is allowed, uncertainty, like ??, is not allowed.
3.1.1. Controls
3.1.2. Functions
3.1.2.1. Hardware Schematics, bill of materials, timing diagrams, etc.
3.1.2.2. Software Flow charts are almost mandatory here.
3.1.3. Calibration Is any required for proper operation?
3.2. Interfaces
3.2.1. Power
3.2.1.1. Electrical
3.2.1.2. Mechanical
3.2.2. LabView Vis (for example)
3.2.3. Other Faceplates
3.3. Physical Dimensions Use English units of measure.
3.3.1. Size
3.3.2. Weight
3.4. Environmental Are there restrictions on the storage, transport or operating environments?
3.5. Materials This is a high level Bill of Material, what are the main components?
3.6. Assembly How does the unit go together? An exploded drawing is very nice.
3.7. Safety What cautions are required to ensure safe assembly or usage?
3.8. Miscellaneous
3.9. Notes
4. Testing It is very important to specify a test plan. It makes you think about what the unit should be capable of, and it becomes the basis of your project demonstration.
5. Reliability How reliable must the unit be? We will discuss MTBF calculations in Design II.
6. Appendices As appropriate
