Closing The Power Integrity Gap

Voltage drop has always been a significant challenge. As far back as 130nm, specialist tools were being used to ensure that enough local decoupling capacitance (decap) cells were inserted in addition to larger decaps implemented around the SoC. But advanced nodes are complicating matters and further increasing complexity. These technological challenges, which underlie the power, performance ... » read more

Blog Review: Oct. 19

Mentor's Colin Walls provides some tips on writing portable, reusable code. Cadence's Christine Young contends that you should never use 2.5D for characterization at advanced nodes. Synopsys' Eric Huang considers one impractical use of USB heating and the IoT. Applied's Ben Lee predicts a rapid growth in China's power device manufacturing. NXP's Joppe Bos digs into the challenges of... » read more

#54DAC: A New Beginning

I’ve been attending DAC as an exhibitor since 1992, and serving on the executive committee since 2012. I am thrilled to serve as General Chair for the 54th iteration of this grand conference. (And no it’s not too early to think about DAC. The call for contributions is open now.) Through the years I have seen some big industry changes, most driven by the increasingly powerful tools and autom... » read more

The Week In Review: Design

M&A Mentor Graphics acquired Galaxy Semiconductor, a provider of test data analysis and defect reduction software ranging from initial characterization of sample devices to automated yield management of large-scale production. The Galway, Ireland company was founded in 1998. Terms of the deal were not disclosed. IP Imagination rolled out a new heterogeneous MIPS CPU with many core/... » read more

How Software-Driven Tests Support Concurrent Power/Performance Analysis

There’s always been an intimate relationship between performance and power—and it’s one that is acutely affected by architecture. Architectural innovation can yield orders of magnitude improvements in performance/power metrics. For example, we’ve seen a growing popularity in multi-core and heterogeneous core systems with purpose-specific hardware accelerators. These configurations are o... » read more

Power Limits Of EDA

Power has become a major gating factor in semiconductor design. It is now the third factor in design optimization, along with performance, and is almost becoming more important than area. But there are limits to the amount of help that [getkc id="7" kc_name="EDA"] can provide with [getkc id="106" kc_name="power optimization"]. Power is not just an optimization problem. It is a design problem... » read more

Betting On Power And Deep Learning

Jim Hogan, managing partner of Vista Ventures, sat down with Semiconductor Engineering to talk about what investments deliver the biggest returns, how quickly, and why there are so few investors in some big growth areas. What follows are excerpts of that conversation. SE: What are you investing in these days and why? Hogan: I have about 15 active deals right now. I generally invest in thi... » read more

Seeing The Future Of Vision

Vision systems have evolved from cameras that enable robots to “see” on a factory floor to a safety-critical element of the heterogeneous systems guiding autonomous vehicles, as well as other applications that call for parallel processing technology to quickly recognize objects, people, and the surrounding environment. Automotive electronics and mobile devices currently dominate embedded... » read more

Getting The Power/Performance Ratio Right

Getting to market quickly means determining as soon as possible if a concept for a new design will work or not, particularly where power and performance are concerned. Making this determination requires intimate knowledge of the scenarios in which the device will operate — and that is just the start. In order to set things up, you need to somehow model the system, which could be done in a ... » read more

Addressing Memory Characterization Capacity And Throughput Requirements With Dynamic Partitioning

Typical memory characterization techniques using memory compilers and instance-specific memories have a number of tradeoffs—development time, accuracy, performance, and more. Ad-hoc instance-specific characterization methods such as dynamic simulation, transistor-level static timing analysis, and divide-and-conquer suffer from multiple limitations that prohibit usage for 40nm technologies and... » read more
