Pragmatic Adoption of Formal Analysis Design How-To 3/29/2007 Post a comment The ability to find bugs can be greatly improved by adopting an assertion based verification (ABV) methodology. ABV is a methodology that uses assertions to increase the productivity and quality of functional verification. ABV provides methods to specify properties and cover points.
For low-power design, speak two languages News & Analysis 3/22/2007 Post a comment It's looking like the impasse between camps supporting Common Power Format and Unified Power Format means that chip designers will need to familiarize themselves with both or hope that translators can make the task easier.
Single-ended design with Digital Amplifiers Design How-To 3/21/2007 Post a comment In practice, single-ended amplifier audio performance data, including power-on pops, signal-to-noise ratio (SNR), PSRR, and THD+N, are quite good with only a small degradation in audio performance from that of BTL.
Handset display driver designers get creative Teardown 3/19/2007 Post a comment
With the multitude of portable systems available on the market today sporting high-resolution displays with rich color depth, it takes effective trade-offs to optimize the design of the display driver ICs. As is the case with most semiconductor development projects, designers of display driver ICs will need to make informed choices if their product is to be commercially successful. They face many interrelated decisions to optimize a design for a particular end application.
Startup makes FPGA prototypes a snap Product News 3/19/2007 Post a comment Startup Eridon Corp. wants to help embedded-systems developers literally snap together an FPGA-based prototype, without their having to understand the hardware or even program the FPGA.
Design for Variability Design How-To 3/19/2007 Post a comment At nanometer technologies, variability is rapidly becoming one of the leading causes for chip failures and delayed schedules. However, there is significant confusion about the term "variability" in the design community today.
CSR brings virtual surround sound to Bluetooth Product News 3/16/2007 Post a comment CSR expanded its portfolio of third-party software for its BlueCore5-Multimedia platform. The BlueCore5-Multimedia External is a single-chip radio and baseband IC for Bluetooth systems. The radio interfaces to up to 32 Mbits of external flash memory.
Accurate Thermal Analysis of Chip/Package Systems Design How-To 3/15/2007 Post a comment With the increasing complexity and power dissipation of modern electronic designs, controlling peak temperature and predicting the temperature profile on the chip early in the process is becoming critical for insuring system reliability. Low power design methodologies create their own thermal challenges, as they may generate "hot" and "cool" regions on the chip. Causes and soutions are explored.
4 steps for managing environmental compliance Design How-To 3/12/2007 Post a comment Without a good set of tools, RoHS compliance management can quickly become a big headache for all parties involved. Following these four steps (including BOM scrubbing, data collection, compliance validation and declaration) is a good place to start.
IGBT tutorial: Part 1 - Selection Design How-To 3/8/2007 6 comments IGBTs are encroaching upon the high frequency, high efficiency domain of power MOSFETs. The industry trend is for IGBTs to replace power MOSFETs except in very low current applications. In part 1 of this two-part article you will understand what IGBTs are, the tradeoffs and how to select one. Part 2 takes a look at an IGBT datasheet.
After 25 years of DSPs, the 'Digital self' emerges--Part I Design How-To 3/8/2007 Post a comment To commemorate the 25th anniversary of its first digital signal processor, here is the first of four articles from Texas Instruments. The first in the series, this article reviews the advancements made by DSPs over the last two and a half decades and examines an emerging 'digital self.'
DSPs to go multicore Product News 3/8/2007 Post a comment The digital signal processor market is moving towards multicore solutions in order to solve a host of new problems.
ARM tips plans for next-generation processor News & Analysis 3/6/2007 Post a comment ARM Holdings plc, the licensor of processors and related intellectual property, has tipped sparse details of plans for a next-generation processor a follow on to the three processor cores the comprise the Cortex series.
Faster verification is the goal at ST News & Analysis 3/5/2007 Post a comment
Laurent Ducousso, who manages intellectual-property (IP) verification for STMicroelectronics' Home Entertainment Division, is a man in a hurry. He's in charge of verification for multimillion-gate systems-on-chip (SoCs) that go into consumer products, which have to ship on time. He's succeeding, thanks to a transaction-level SystemC-based approach that both speeds things up and greatly reduces the overall bug count. But debugging and software verification remain challenging. Ducousso recently
Under the Hood: The MP3 that broke new ground Teardown 3/5/2007 Post a comment In tidying up the Portelligent "morgue," which has product teardowns dating back to the early 1990s, an old gem resurfaced: the Diamond Rio PMP300 MP3 player. Check out David Carey's breakdown of one of the earliest MP3 players.
