Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post-silicon validation tests face challenges in efficiently managing resource conflicts between multiple actions addressing a single resource, leading to potential failures and inefficiencies in testing electronic systems.
Innovation Solution
A method and system that automatically generate target code with resource management commands, such as lock commands, to prevent conflicting addressing of resources, allowing for the combination of scenarios and looped execution to create diverse and efficient validation tests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple actions are allowed to address a single resource concurrently in validation tests, then test execution time is reduced and productivity is improved, but resource conflicts occur leading to test failures and reliability deterioration
Solution Approach 1:
The patent introduces an intermediary mechanism (lock command system) that mediates access to shared resources between multiple concurrent actions. The lock commands act as intermediaries that coordinate resource access, allowing concurrent execution while preventing conflicts through structured access control protocols.
Solution Approach 2:
The patent applies preliminary action by acquiring locks before accessing shared resources. The lock commands are executed in advance of the actual resource access operations, ensuring that resource conflicts are prevented before they can occur during concurrent test execution.
2Reliability
If resource management commands are added to prevent conflicts, then test reliability is improved, but device complexity and code complexity increase
Solution Approach 1:
The patent implements self-service by having the test generation system automatically insert appropriate lock commands into the test code without requiring manual intervention. The system analyzes the test scenario, identifies potential resource conflicts, and autonomously generates the necessary resource management commands, reducing the perceived complexity for users.
Solution Approach 2:
The patent extracts the complexity of resource management from the user's responsibility by automatically generating lock commands. The complex logic for determining when and where to apply resource management is separated from the test scenario definition, allowing users to focus on test logic while the system handles resource coordination.
3Manufacturing precision
If manual creation of validation tests is performed, then test precision and coverage are improved, but user effort and time consumption increase
Solution Approach 1:
The patent enables self-service by allowing the system to automatically generate test code from high-level test scenario descriptions. Users define the test logic and resource access patterns at an abstract level, and the system automatically generates the complete test code including necessary lock commands, significantly reducing manual coding effort while maintaining test quality.
Solution Approach 2:
The patent applies preliminary action by pre-generating test code templates and resource management structures before actual test execution. The system prepares the test framework, identifies resource access patterns in advance, and generates optimized test code, reducing the time required for manual test creation and setup.
Data Source
AI summary
A method for generating a validation test may include using a processor, identifying, in a scenario for validation testing, a plurality of actions that address a single resource in a conflicting manner; and automatically generating target code of the scenario that includes one or a plurality of resource management commands so as to prevent conflicting addressing of that resource by said plurality of actions.
