Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current simulation methods, such as event-driven and time-driven simulations, struggle to accurately simulate the interaction between applications and devices, as they either fail to simulate device operations effectively or resource limitations lead to inaccurate performance evaluations.
Innovation Solution
A computation scheme that coordinates two computation techniques, one based on an event-driven basis and the other on a time-driven basis, using a coordination system to synchronize and adjust for interactions between the two, enabling accurate performance analysis by exchanging I/O requests and timing information through shared memory.

Engineering Contradiction Analysis
1Measurement precision
If event-driven simulation is used to simulate device operations, then device operation simulation accuracy is improved, but interaction simulation with applications deteriorates
Solution Approach 1:
The patent combines event-driven simulation and time-driven simulation into a hybrid simulation system. The event-driven component accurately simulates device operations, while the time-driven component handles application interactions and I/O requests. These two simulation methods are merged through a coordination mechanism that allows them to work together, resolving the contradiction between device operation accuracy and interaction simulation capability.
Solution Approach 2:
The simulation system is segmented into distinct components: an event-driven simulation module for device operations, a time-driven simulation module for application behavior, and a coordination module that manages interactions between them. This segmentation allows each component to specialize in its strength while the coordination mechanism ensures overall system consistency.
2Productivity
If time-driven simulation is used to simulate application operations, then application performance simulation is improved, but device operation simulation accuracy deteriorates
Solution Approach 1:
The hybrid simulation system merges time-driven simulation for application operations with event-driven simulation for device operations. The time-driven component handles application I/O requests and performance metrics, while the event-driven component maintains accurate device operation modeling. The coordination mechanism integrates these complementary capabilities.
3Device complexity
If single-method simulation is used, then system complexity is reduced, but simulation accuracy deteriorates
Solution Approach 1:
The patent merges multiple simulation methods (event-driven and time-driven) into a unified hybrid system. While this increases system complexity, it dramatically improves simulation accuracy by leveraging the strengths of each method. The coordination mechanism manages the complexity through structured interaction protocols and shared data structures.
Solution Approach 2:
A coordination module acts as an intermediary between the event-driven and time-driven simulation components. This mediator manages the complexity by handling communication, synchronization, and data exchange between the two simulation methods, allowing them to work together without direct complex interactions.
4Measurement precision
If event-driven simulation is used, then device operation detail is improved, but resource consumption increases
Solution Approach 1:
The simulation workload is segmented between event-driven and time-driven components. The event-driven portion handles only device operation events, maintaining detailed accuracy where needed, while the time-driven portion handles application-level simulations with lower resource requirements. This segmentation optimizes resource distribution according to the specific needs of each simulation type.
