Power Flow Architecture for Electronic System Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic system design, there is a disconnection between system architecture development and power analysis, leading to architecture translation errors and power information errors due to the lack of informational links between the two processes, resulting in inefficient power consumption optimization.
Innovation Solution
A method and apparatus that convert system architecture to power flow architecture, designate power domain types, and perform power roll-up calculations to provide accurate system power estimations, utilizing Model-Based Systems Engineering (MBSE) and Systems Modeling Language (SysML) to integrate power information and analysis within the design process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If system architecture development and power analysis are performed separately, then each team can focus on their specific tasks, but information disconnect occurs leading to architecture translation errors and power information errors
Solution Approach 1:
The patent merges system architecture development and power analysis into a unified model-based systems engineering framework. A single system model serves both architecture definition and power analysis purposes, eliminating the need for separate teams and information transfers. The model includes both architectural elements and power domain information, allowing simultaneous development and analysis.
Solution Approach 2:
The patent introduces a power flow architecture as an intermediary representation that bridges system architecture and power analysis. This intermediary model transforms architectural information into power domain information while maintaining traceability. The power flow architecture acts as a mediator that preserves information integrity during the transition from architectural design to power analysis.
2Productivity
If power analysis is performed after system architecture development, then architecture can be established first, but traceability and version control are lost
Solution Approach 1:
The patent performs preliminary power analysis setup during system architecture development rather than after. Power domains, power converters, and power consumers are defined within the architecture model itself, enabling power analysis to be performed at any stage with full traceability to the architectural decisions that define the power requirements.
3Adaptability or versatility
If manual architecture to power analysis conversion is performed, then flexibility in analysis approach is maintained, but translation errors occur without traceability
Solution Approach 1:
The patent replaces manual conversion processes with automated model-based transformation. The system automatically transforms architectural elements into power analysis elements using defined relationships and constraints within the model. This automated mechanism eliminates human error while preserving the flexibility to choose different analysis approaches through model configuration rather than manual procedures.

AI summary
A method for providing a power estimation for an electronic system is disclosed. Initially, a system architecture of an electronic system design is initially developed, and the system architecture of the electronic system design is then converted to a power flow architecture of the electronic system design. For each power domain within the power flow architecture of the electronic system design, a power domain type is designated. Subsequently, power information are added to the power flow architecture of the electronic system. Finally, a power roll-up calculation is performed on the power flow architecture of the electronic system design in order to yield a final system power value for the electronic system design.
