Control Unit for Automated Software Build Tool Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current software build processes for safety-critical systems are resource-intensive and error-prone, particularly in large-scale projects, due to the need for manual reviews and parallel build systems, which are time-consuming and prone to human errors, making it difficult to ensure tool integrity and safety compliance.
Innovation Solution
A control unit with interfaces to communicate with multiple tools and processing circuitry to determine and monitor the tools used during the software build process, allowing for automated verification of tool usage, safety rule definition, and authorization management to ensure compliance with safety protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual review of software build process scripts is performed, then verification of tool usage can be achieved, but the process becomes time-consuming and error-prone in large-scale projects
Solution Approach 1:
The patent replaces manual mechanical review processes with automated electronic monitoring and analysis systems. The control unit automatically collects data from build tools, analyzes scripts, and verifies tool usage without human intervention, thereby eliminating time-consuming manual reviews while maintaining verification accuracy.
Solution Approach 2:
The patent introduces a control unit as an intermediary between the build tools and the verification process. This intermediary automatically monitors tool usage, collects execution data, and performs verification activities, freeing human reviewers from manual tasks while ensuring comprehensive and accurate verification.
2Reliability
If parallel build systems are used to verify tool integrity, then verification can be performed, but resource consumption increases significantly
Solution Approach 1:
Instead of creating full parallel build systems, the patent uses a control unit that collects and analyzes data from the actual build process. It creates virtual representations of tool usage through logging and monitoring, enabling verification without duplicating the entire build infrastructure and its associated resource consumption.
Solution Approach 2:
The patent replaces resource-intensive parallel build execution with automated monitoring and analysis mechanisms. The control unit observes and records tool usage during normal builds, then analyzes this data to verify integrity, eliminating the need for separate parallel build systems while maintaining verification capability.
3Manufacturing precision
If manual review processes are used for safety verification, then quality control can be achieved, but human errors reduce reliability in large-scale projects
Solution Approach 1:
The patent implements self-service verification where the control unit automatically performs quality control checks without human intervention. The system monitors itself, collects data from build tools, and verifies compliance with safety requirements autonomously, eliminating human errors while maintaining consistent quality control across all build processes.
Solution Approach 2:
The patent establishes automated feedback loops where the control unit continuously monitors tool usage, compares it against safety requirements, and provides immediate verification results. This automated feedback mechanism ensures consistent quality control without human error, as the system objectively evaluates compliance based on predefined criteria.
4Measurement precision
If comprehensive monitoring of all build tools is implemented, then verification accuracy improves, but system complexity increases
Solution Approach 1:
The patent implements a universal control unit that can monitor and verify multiple different build tools through a single interface. This multi-functional system handles various tool types (compilers, linkers, code generators) using standardized methods, achieving comprehensive monitoring accuracy while minimizing system complexity through consolidation rather than separate specialized monitors for each tool.
