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.

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

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.
