When laying out an MCU-based design, basic checks include the following:
1. Determine goals: Clarify design goals, such as functional verification, performance evaluation, power consumption testing, etc. This helps determine testing methods and strategies.
2. Select appropriate tools and platforms: Based on design requirements, select appropriate hardware and software tools, such as development boards, compilers, debuggers, etc.
3. Determine key technologies: Analyze key technical points in the design, such as clock configuration, memory access, input/output interfaces, etc., to ensure that these key points are handled appropriately.
4. Check the electrical performance: Based on parameters such as circuit design and power supply voltage, check the electrical performance of the signal, such as the value and function of resistors, capacitors, inductors and other components.
5. Thermal design considerations: Evaluate the heat generation based on the power consumption of the circuit board and components, and consider heat dissipation solutions and material selection.
6. Signal integrity analysis: Analyze signal integrity, timing, noise and other issues through simulation or actual testing to ensure that signal quality meets design requirements.
7. Electromagnetic compatibility (EMC) considerations: Evaluate the electromagnetic radiation and anti-interference performance of circuit boards and components to ensure that relevant standards and regulatory requirements are met.
8. Safety considerations: Based on circuit design and component selection, evaluate potential safety risks, such as overvoltage, overcurrent, short circuit, etc., and take corresponding protective measures.
9. Cost and manufacturability: Evaluate the cost, manufacturing cost and maintainability of the design to ensure that market and production requirements are met.
10. Determine the test plan: Based on the design goals and the results of the above inspections, develop a detailed test plan, including test cases, test environment, test tools and methods, etc.
Through the above basic inspection, you can ensure that the design layout based on MCU is reasonable, feasible and meets the actual application requirements.
