When you think Apache Design you probably think Low Power Design and what stuffed animal will they give away at DAC. The other thing you should think about is how the top semiconductor companies around the world use Apache products for leading edge semiconductor design. Demos are fine, but there is nothing like talking directly to designers who use the tools in an intimate setting (20 people). You definitely do not want to miss this opportunity to collaborate but space is limited so register now:
Design experts from AMD, ARM, Freescale, LSI, Nvidia, Samsung, and STMicroelectronics will share best practices and in-depth experiences on how they successfully achieve power, performance,reliability, and cost targets.
AMD: Unified Method for Package-Induced Power Supply Droop Analysis in High Performance Processors:
Excessive supply voltage droop can have a significant impact on the clock frequency of high-performance processors. In this work we present a unique approach for power supply droop analysis. A detailed model of the package extracted from layout is combined with a representative model of the IC to simulate dynamic supply voltage gradients across the die. The IC model is geared towards accurate prediction of voltages on power supply C4 bumps. At the same time, it is compact enough to allow efficient simulation of the complete chip-package system. We used this methodology to simulate the droop on a high-performance server SoC. Dynamic simulations were performed with patterns exercising high-power sections of the CPU cores on the SoC. The simulated droops correlate very well with silicon characterizations performed on the same design. We discuss the use of this methodology in future for early analysis of chip/package systems and for driving both IC and package design decisions.

Samsung-SSI: The Life of PI: SoC Power Integrity from Early Estimation to Design Sign-off:
The life of Power Integrity (PI) analysis starts at the product infancy stage. Early analysis involves resource allocation at the system level, such as the VRM, board, and package, and at the chip level, in terms of power grid structure, power scenario analysis, and the amount and placement of intentional decoupling capacitance (DECAP). This is done through systematic PI modeling and simulation. As the design matures, the power integrity engineer gets more information on the system and on the die. There are many phases of progressive iterations to evaluate design tradeoffs. Power integrity engineers work closely with board, package, and chip design teams to achieve PI closure. At the design tape out stage, the power integrity team is responsible for signing off static and dynamic IR drop and EM to verify that multi-million gates SoC chips meet stringent power supply noise budget. We investigated the impact of board, package, package embedded with DECAP, power grid, circuit switching activity, as well as on-die DECAP and demonstrated good correlation between early estimation and the final analysis with detailed chip and package models.

STMicroelectronics: RTL Power Estimation on ARM Core Sub-systems:
I will start my presentation with an introduction about High Performance Power Efficient ARM Cores implementation within ST and the associated challenge of estimating dynamic power early in the implementation flow. Then I’ll present results obtained when benchmarking PowerArtist tool by measuring accuracy versus signoff power figures on a Dual-cortex A9 subsystem. I will pursue by explaining how we have used PowerArtist tool on a Dual-Cortex A15 subsystem and the different results we have obtained. Finally, I’ll finish my presentation with a conclusion on the benefits of PowerArtist tool.

GlobalFoundries: Hierarchical Voltage Drop Analysis Techniques for Complex Power-Gated Multi-Domain 20nm Designs:
When qualifying new technologies for new design nodes (e.g. 20nm, 14nm…), large SRAM arrays with many power domainsare employed. Since the VMIN characterization of bit cells performed on silicon requires a sufficient power/ground network, an IR drop analysis at the transistor-level for the whole design is required. This presentation will cover a hierarchical IR drop analysis flow using new capabilities within Totem to trace networks of multi power domains (>800) through switch cells, and to generate subblock abstracts for different detail levels. The abstracts can then be used for top-level analysis; allowing a large speed-up of IR drop analysis in comparison to flat analysis. This presentation also includes a discussion about the pros and cons of the approach and will present resource requirements (run time, memory).
