PrimeTime Special Interest Group (SIG) at SNUG India 2015

The Synopsys PrimeTime SIG is an active community for all PrimeTime users and design engineers who want to stay connected with the latest developments in the field of Static Timing Analysis (STA).

SNUG India PrimeTime SIG Event

Maximizing Design Productivity with Advanced Signoff Technologies

A PrimeTime SIG event, “Maximizing Design Productivity with Advanced Signoff Technologies,” was held at Leela Palace, Bangaluru, India during India SNUG on June 24, 2015. PrimeTime users and managers from top semiconductor companies attended the event. 

Customer speakers from Qualcomm and STMicroelectronics presented their timing signoff and closure experiences with advanced signoff technologies of PrimeTime, and StarRC.

Speakers

Anand Bariya

Broadcom

Anand, Senior Director, kicked off the event and shared his vision and expectation of advanced timing methodologies. He also moderated the event and Q&A session.

Alireza Kasnavi

Synopsys

Alireza, Director of Engineering for the PrimeTime team, presented an overview of the latest innovation of timing (IoT), including a review of recent customer successes with advanced signoff technologies, previewed some exciting upcoming features, and shared Synopsys' vision of the future of signoff timing. 

Naishad Parikh

Qualcomm

Naishad shared the key challenges in timing signoff as his designs move to advanced technology nodes, such as growing design size and increased variation. He highlighted the benefits of Parametric On-Chip-Variation (POCV) Liberty Variation Format (LVF), including improved variation accuracy and less pessimistic graph-based analysis (GBA) reporting compared to Advanced On-Chip-Variation (AOCV). He also shared the successful 10nm tapeout experience with HyperScale, which reduced the full-loop engineering change order (ECO) turnaround time (TAT) by 25%. 

Renuka Deshpande

STMicroelectronics

Renuka shared how PrimeTime physically-aware ECO resolves the timing closure challenges in multi-scenario designs. She also showed how PrimeTime ECO noise fixing resolved noise violations in top channels that previously could not be fixed by wire spreading, and why the unique capability of fixing violations at the coupling source achieves best quality-of-results (QoR). In addition, she described how StarRC simultaneous multicorner (SMC) and ECO extraction cut runtimes by 3X and disk space by 2X using the same number of cores more efficiently.
