Design Notes Template
Design Notes document the reasoning behind specific design choices, trade-offs, implementation details, and lessons learned during the development of a system or subsystem.
They complement architecture entries by providing deeper insight into the decision-making process.
Context
Describe the context in which this design note applies:
- subsystem or module
- problem being addressed
- constraints or requirements
- relevant architectural references
Problem Statement
Clearly define the problem or design challenge.
Explain why it matters and what impact it has on the system.
Design Options Considered
List the possible approaches evaluated, with a short description for each:
- Option A: description
- Option B: description
- Option C: description
This section should remain concise and focused on the alternatives.
Trade-Off Analysis
Analyze the pros and cons of each option.
Typical factors include:
- performance
- area / cost
- power consumption
- complexity
- maintainability
- scalability
- risk
Use bullets or short paragraphs for clarity.
Chosen Solution
Describe the selected approach and explain why it was chosen over the alternatives.
Highlight the key factors that drove the decision.
Implementation Notes
Provide details relevant to implementation:
- interface assumptions
- timing considerations
- dependencies
- corner cases
- integration notes
- known limitations
This section is practical and hands-on.
Verification & Validation
Describe how the solution was verified:
- simulation strategy
- testbench structure
- coverage goals
- hardware validation (if applicable)
Lessons Learned
Capture insights gained during the design process:
- what worked well
- what caused issues
- what you would do differently next time
This section is extremely valuable for future reuse.
References
List any relevant documents, architecture entries, standards, or external sources.
