Automated IR-ECO Flow : Reducing PDN Violations upto 40-50% and Saving Weeks of Engineering Effort
DescriptionAddressing Power Delivery Network (PDN) violations across multiple scenarios within tight tape-out timelines has been a significant challenge due to the extensive manual effort required. Identifying root causes, implementing engineering change orders (ECOs), and validating their impact on both timing and violations demand considerable time and resources, making it impractical to complete within deadlines. To overcome this, a new multi-scenario IR-ECO flow was developed, offering an automated solution to reduce PDN violations efficiently.
This flow employs voltage impact technology from IR/EM tool (RHSC) to automatically identify root cause aggressors for violations across various scenarios. An ECO tool (Tweaker) communicates with the IR/EM tools to perform quick what-if evaluations, enabling the seamless generation of ECOs which are validated for timing and effectiveness across all scenarios. The flow prioritizes aggressors common to multiple violations, ensuring an optimal fix rate while preventing negative impacts on timing.
When tested on a large design, the IR-ECO flow achieved a 40-50% reduction in violations across four scenarios with overnight run time. By automating previously manual and time-consuming processes, this solution eliminates the need for waivers and excessive routing resources, freeing up weeks of engineering effort and accelerating the tape-out process while ensuring timing integrity.
