What's the latest after 3G & 4G? Is there anything like 5G?

Posted: 02 Dec 2010 11:49 AM PST

Just thought of keeping my knowledge updated. I've heard that couple of network providers in the USA are already offering 4G services and download speeds up to 6-8 mbps. As far as I know, 4G services offer speeds upto 100 mbps.

Is there something like 5G being worked on at present? If anyone knows, please post information about it in this thread. If 4G is the limit, what's next?

Icera and Magma Collaborate on Next-Gen Soft Modem Chipsets

Posted: 02 Dec 2010 08:43 AM PST

SAN JOSE, Calif., and Bristol, UK, Dec. 2, 2010 – Magma Design Automation Inc. (Nasdaq: LAVA), a provider of chip design software, and Icera Inc., a pioneer in soft modem chipsets for smartphones and mobile broadband devices, today announced joint development of Icera's 28-nanometer (nm) high-performance, low-power system-on-chip (SoC) design flow for its next-generation chipsets. Icera devices are used by OEMs globally to deliver extremely small, fully software-based multimode 4G LTE/3G/2G cellular modems for smartphones, and mobile broadband devices such as USB sticks, tablets and netbooks. Icera chose Magma's Talus platform because it provides a highly integrated flow that enables Icera to address 28-nm design complexity, improve area efficiency and reduce power consumption while accelerating turnaround time.

"To maintain technical leadership in the cellular modem business, Icera cannot afford to compromise on performance, power consumption or area efficiency," said Peter Hughes, vice president of Silicon Engineering and Operations at Icera. "The advanced technology and tight integration of the Talus platform enable Icera to meet our stringent power and area targets and to reduce time to market for our next-generation 28-nm soft modem chipset."

"The recent enhancements to the Talus platform were developed specifically to address increasing design complexity at the 28-nm node while improving designer productivity dramatically," said PremalBuch, general manager of Magma's Design Implementation Business Unit. "Offering the capacity to process 1 million cells per day, integrating the Tekton-based MX timing engine to ensure correlation and accelerate timing closure, and supporting advanced low-power design techniques, Talus is the clear path to 28-nm and smaller SoCs."

Talus 1.2 Increases Implementation Throughput, Decreases Power for Icera Chipsets
Talus 1.2's new advanced on-chip variation (AOCV) driven optimization significantly reduces pessimistic design margins that are required in traditional flows, and Icera plans to leverage this capability to improve the performance of its soft modem chipsets. Unlike other approaches, this optimization is performed throughout the Talus flow, providing convergent and robust timing while at the same time reducing any area penalty related to OCV effects. With Talus 1.2 designers can improve silicon correlation and minimize power consumption.

Talus 1.2's advanced clock gating techniques help customers significantly reduce both area and power, particularly in the clock network. This allows the core processing functions to achieve required operating frequencies while remaining within a tight power budget.

In addition, Talus 1.2 offers tight timing correlation throughout the flow and timing sign-off through its new MX timing engine derived from Tekton™, Magma's extremely fast and accurate standalone static timing analyzer. With reliable timing numbers that Talus delivers early in the design process, designers can make better design decisions throughout the flow and have confidence in achieving timing convergence faster.

Magma Unveil New Talus 1.2 next-generation SoC solution

Posted: 02 Dec 2010 06:11 AM PST

SAN JOSE, Calif., Dec. 2, 2010 –– Magma® Design Automation Inc. (Nasdaq: LAVA), a provider of chip design software, today unveiled Talus® 1.2, a next-generation integrated circuit (IC) implementation solution that accelerates the design cycle of systems on chip (SoCs). The new Talus system enables engineers to implement 1 million to 1.5 million cells per day on large designs or blocks of 2 million to 5 million cells – with crosstalk avoidance, advanced on-chip variation (AOCV) and multi-mode multi-corner (MMMC) analysis enabled. Already silicon-proven at the 40-nanometer (nm) node, Talus is currently in use for complex 28-nm designs. With these latest enhancements, Talus is primed to handle the challenges of designing at the 20-nm process node and beyond.

Talus 1.2 leverages faster, more accurate routing, timing and extraction technologies and advanced capabilities to deliver five to six times faster turnaround time, including:
• Talus MX Router: Offers enhanced global, track and detailed routing capabilities, convergent timing through the flow, and eliminates DRC violations.
• Talus MX Timer: Based on Magma's next-generation sign-off timing analysis technology, enables faster more accurate timing analysis.
• Talus MX Extractor: Based on Magma's latest high-speed, multi-corner extraction technology, provides faster, more accurate extraction.
• Concurrent MMMC optimization: Manages five times as many timing scenarios than traditional solutions, while providing a 10X runtime improvement.
• AOCV: Ensures tight timing correlation throughout the flow.
• Crosstalk Avoidance: Detects and corrects crosstalk violations during optimization and implementation.

"The positive results we achieved from Magma's Talus 1.2 platform reaffirmed our decision to select this tool to support our complex silicon project needs," said George Apostol, executive vice president of Engineering and Operations, and chief technical officer at Exar Corporation. "Critical to our customers, our devices must support high levels of data traffic without bottlenecks, requiring efficient routing. Talus 1.2 has solved many physical design issues and has improved place and route runtimes over prior releases, enabling us to shorten development cycles and accelerate shipping next-generation devices to customers to meet dynamic market requirements."

"Chip design teams are under constantly increasing pressure to improve productivity, even as the designs they tackle grow in size and complexity," said PremalBuch, general manager of Magma's Design Implementation Business Unit. "Economics dictate that design teams cannot expand in proportion with growing design sizes, nor can turnaround times lengthen. To improve productivity, tools must provide more capacity and faster turnaround times while enabling designers to squeeze out more performance and reduce power consumption in their SoCs. Talus 1.2 does just that. It delivers the fastest turnaround times, highest capacity, and best quality of results for the next generation of IC designs at the 28-nm process node and below."

Talus 1.2: Faster Turnaround Times, Superior Results
Key enabling technologies in Talus 1.2 include the new Talus MX timing and extraction engines based on underlying technology borrowed from Magma's next-generation sign-off timer, Tekton™, and sign-off extractor, QCP™. Used consistently throughout Talus 1.2's RTL-to-GDSII flow, these analysis engines are fast, accurate and have significantly higher capacity. They offer new features such as AOCV and MMMC analysis, ensuring tight timing correlation throughout the flow. When combined with Tekton and QCP, Talus 1.2 provides sign-off-accurate analysis during implementation, eliminating timing ECOs and resulting in faster design closure.
For implementation at 28 nm and below, it's not uncommon for designs to require the analysis of many different timing scenarios. Magma defines timing scenarios as the number of process corners multiplied by the number of timing modes. Most solutions can only handle five to eight scenarios during implementation. Talus 1.2 performs concurrent MMMC on a single machine and can manage five times more scenarios than traditional solutions, while improving runtime by 10 times.
Talus 1.2's new routing technology addresses routing challenges at 28 nm and below, where managing crosstalk in particular becomes more difficult. Fixing crosstalk too late in the flow results, in the best case, in higher cell area and elevated leakage. In the worst case, it results in a design that will not close. Talus1.2 avoids this by identifying and controlling crosstalk throughout implementation, providing a much more convergent flow with far fewer timing surprises. Unlike other approaches, Talus 1.2 delivers far shorter runtimes and more robust designs, without increasing area and leakage.
The combination of Talus 1.2's new technologies enables designers to deliver high-performance designs quickly. For example, a networking company was able to implement a 40-nm, 2-million-instance design with 10 sign-off scenarios in just 2 days with full CCS, MMMC and crosstalk analysis enabled.

TCS Campus Recruitment Procedure

Posted: 01 Dec 2010 07:25 PM PST

TCS is hiring in full swing and visiting campuses for hiring candidates in December - January. Those who are looking for detailed recruitment procedure - here's it:

To be taken in the campus computer network -

1. Aptitude Test: 90 Minutes for 90 questions

The test contains many aptitude questions which aren't very tough. You can move around questions and revisit the questions if you skipped them in the first 'go around' the question set. However, there are three sections [Verbal, Quantitative & Reasoning] and you *cannot* return to a section once you've left it.

2. Psychometric Test: 30 Minutes for 120 questions

I always wondered why TCS has this test in its campus recruitment process. Lot of students fear this test as there is 'nothing' really prepare for. So here's a tip for all of you: Just answer all the questions with positive attitude. This test is a multiple-choice question. For example if the question is "While organizing a friend's birthday party", opt for answer that is most positive and energetic (like "I take the lead and organize it").

Also, another most important tip is "Stick to the 'positive' tone" you've adopted. It's very important as the questions will be presented to you random order.

3. Technical Interview:

You'll be questions mostly on your final year/third year project and basic programming skills. Also be prepared to answer few questions on your engineering trade.

4. Personal Interview:

If you've reached the Personal Interview, there's a 99% chance you'll get through. Just answer all the question, have good communications skills and be confident, not over-confident.

If you want further tips or have questions, do ask in this thread. We've couple of CEans who work in TCS and they might want to respond to your questions.
