Presentation
An Efficient Methodology for Multi-PVT EMIR Analysis of Large SOCs
DescriptionThe existing power integrity workflow, which uses Ansys's tool RedHawk_SC, enables users to launch many targets, such as IR-drop and Electromigration analysis, Resistance Checks, SigmaDVD, and reporting of results. With this flow NVIDIA has closed many projects, but as the sizes of designs grow, there are some issues with the flow, such as high license, runtime, diskspace and machine usage, runtime stalls, and run crashes due to high peak memory. To address these run and flow issues, New Flow (Multi-PVT/Multi Target Flow) was developed, with optimized code based on Ansys tool features, such as Seascape User View, Seascape Delayed Objects, and Map Reduce architecture. New Flow enables target runs to be done in parallel re-using the views generated by earlier targets, avoids duplicate collateral setup, and saves the minimum views needed for the analysis across all scenarios. These benefits improve user experience and reduce time to close projects (since more runs can be done in parallel due to improved runtime and efficient resource usage).
