Solution Overview

Problem

Existing electronic design automation (EDA) protocols face challenges in efficiently tuning parameters across multiple stages, often requiring extensive human expertise and failing to optimize runtime effectively, as they either focus on single stages or tackle multiple stages as a whole, leading to a huge search space and neglecting runtime optimization.

Innovation Solution

A multi-stage cooperative co-evolutionary framework is employed to tune EDA protocol parameters, sharing knowledge across stages, utilizing optimization algorithms like ant colony optimization, and deploying jump-start and early-stop techniques to enhance runtime efficiency and resource management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple stages are tuned as a whole, then comprehensive optimization is achieved, but the search space becomes huge and runtime increases

Engineering Contradiction:
Improveoptimization effectivenessVSAvoidruntime
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent divides the multi-stage EDA protocol into separate stages, each with its own optimization component. Each component independently optimizes parameters for a specific stage, breaking down the huge search space into manageable segments. This segmentation allows for more efficient exploration of parameter spaces while maintaining comprehensive optimization across all stages.

Inventive Principle:

Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where optimization components share learned information and parameter knowledge across stages. Each stage's optimization results feed into subsequent stages, allowing individual stage optimization to contribute to overall system optimization. This feedback loop ensures comprehensive optimization is achieved without requiring simultaneous optimization of all stages.

Inventive Principle:
