Streamlining ECO Processes in Digital Chip Physical Design

Key Takeaways

• Automated Root Cause Analysis: The platform leverages AI to identify and prioritize timing violations efficiently.

Introduction

The Engineering Change Order (ECO) process is a pivotal phase in digital chip physical design, marked by iterative modifications to address functional or parametric refinements post-design completion. Despite its critical importance, the ECO process is notoriously time-consuming, labor-intensive, and resource-heavy, primarily due to challenges such as the Adaptation Effect, Cascade Effect, and Chain Effect. To address these challenges, developing an "Easy ECO Platform" is essential. This platform aims to streamline the ECO process, enhance efficiency, and reduce the manual burden on Physical Design (PD) engineers by automating analysis, root cause identification, and the generation of adaptive fixing strategies.

Objectives

• Automate ECO Process: Minimize manual intervention by automating time-consuming tasks within the ECO cycle.
• Optimize Patch Selection: Implement intelligent algorithms to select the most effective patches for resolving timing violations.
• Manage Cascade and Chain Effects: Prevent new violations from arising due to modifications and ensure sequential resolution of dependent issues.
• Root Cause Analysis: Efficiently analyze timing reports to identify the underlying causes of violations.
• Adaptive Fixing Recipes: Develop dynamic strategies that adjust based on iterative analysis and outcomes.
• User-Friendly Interface: Provide an intuitive platform for PD engineers to interact seamlessly with the ECO process.
