Engineering Scope
Existing product power consumption diagnosis and optimization are used to solve specific engineering problems in low-power projects. The work starts from the customer's existing design and business requirements, establishes a baseline, correlates current events and logs, locates leakage, spurious wake-up, and retries; delivers problem evidence, modification plans, change documents, and before-and-after comparisons of the same working conditions according to the agreed modules.
Check input with baseline
Check the prototype, version, schematic diagram, source code, reproduction steps and on-site conditions, and clarify the scope of measurement and modification.
Implementation and adaptation
Establish a baseline, correlate current events and logs, locate leakage, spurious wake-ups and retries, and record solution choices and dependency conditions.
Target environment joint debugging
Retest the problem scenario and return the function, retain the unchanged conditions and residual consumption, and confirm the business behavior after parameter changes.
Document and record delivery
Provide problem evidence, modification plans, change files, and comparisons of the same working conditions, and explain the version, construction or usage method.
Project Workflow
- Input confirmation: prototype, version, schematic diagram, source code, reproduction steps and on-site conditions.
- Implementation method: Establish a baseline, correlate current events and logs, locate leakage, spurious wake-up and retry.
- Stage review: retest the problem scenario and return the function, retaining unchanged conditions and residual consumption.
- Project delivery: problem evidence, modification plan, change documents and before and after comparison of the same working conditions.
Design Conditions and Functional Limits
Reproducible baselines and positioning evidence should be established first before deciding on the scope of modifications; otherwise it will be difficult to determine whether the benefits come from changes in design or changes in test conditions.
Special services take the agreed module as the implementation boundary. When hardware modifications, third-party agreements, overall platforms or external tests are involved, the interfaces, workload and responsibilities are confirmed separately, and local modifications are not directly used as conclusions on the performance of the complete device.
Project Inputs
- Prototype, version, schematic diagram, source code, reproduction steps and on-site conditions.
- Existing prototypes and reproducible problems, or new project functionality and power consumption targets.
- Modified design, source code and third-party dependencies are allowed; functionality and compatibility need to be maintained.
- Delivery list, target environment, sample scope, project milestones and acceptance methods.
Delivery and Acceptance
| Delivery content | Check method |
|---|---|
| Problem evidence, modification plans, change documents and before and after comparison of the same working conditions | Check the editability, version, usage instructions and dependencies by file list. |
| Implementation verification | Retest the problem scenario and return the function, retain the unchanged conditions and residual consumption, and retain the corresponding working conditions and results. |
| Comparison of functions and power consumption | Fixed applicable hardware, software, battery, temperature and business cycles, accounting for changes in conditions and their impact. |
| Reproduction and follow-up maintenance | Provide build or run steps, known limitations, parameter ranges, and uncovered cases. |
Frequently Asked Questions
Does the circuit or program have to be modified first?+
Reproducible baselines and positioning evidence should be established first before deciding on the scope of modifications; otherwise it will be difficult to determine whether the benefits come from changes in design or changes in test conditions.
What information do I need to prepare before starting the project?+
The focus of this work requires prototypes, versions, schematics, source code, reproduction steps and on-site conditions. When the data is incomplete, first determine the scope that needs supplementary testing or sorting out, and then proceed to implementation.
Can it be implemented together with the complete device development project?+
It can be used as a work package in the overall project, or it can be implemented separately for existing products. It is necessary to explain the interfaces with other modules, versions and final machine verification responsibilities.
