Pitfalls In Subsystem Reuse


By Ann Steffora Mutschler IP subsystems provide a ‘divide and conquer’ approach to SoC design by combining multiple IP blocks together to perform individual functions such as audio, graphics or video. The advantage of this approach is that these functions can be tested and verified at the unit level then integrated with the top-level SoC. This also facilitates reuse because each of ... » read more

Experience Required


Many prominent semiconductor, EDA and IP companies are acknowledging the influence of user-experience design methodologies and technologies on their business. Experiences are the evolution of commoditization (chip hardware) and customization (software). But many design engineers remain cautious about the actual application of experiences to their work. What is driving this emphasis on expe... » read more

Shifts In Verification


By Ann Steffora Mutschler Verifying an SoC requires a holistic view of the system, and engineering teams use a number of tools to reach a high degree of confidence in the coverage. But how and when to use those tools is in flux as engineering teams wrestle with increasing complexity at every level of the design, and a skyrocketing increase in the challenge of verifying it. There are no ... » read more

Beyond Software: The Virtual-Machine Supply System


It’s no secret that EDA and IP companies have had to expand their coverage into the larger system market, thanks to changes in the semiconductor supply chain. Around 2000, the industry was very fragmented. Mobile-chip and IP vendors worked with handset makers, who then partnered with operating-system (OS) suppliers and finally network operators. The next 12 years resulted in various combinati... » read more

Taking Aim At Big Data


By Ed Sperling As the Internet of Things bridges the gap between the mobile and big data worlds, EDA and IP vendors increasingly are looking well beyond their usual boundaries. How successful they are at moving upward into a market that is far less price-sensitive remains to be seen. But from a technology standpoint, at least, the issues encountered by data centers and cloud providers are ... » read more

Design Topology Requires Physical Data


By Ann Steffora Mutschler To best understand a design topology and make decisions on clock/register gating, vector sets are required for the RTL tools to understand how to gate clocks and registers. However, if certain constraints are set on all enabled signals in RTL they can be re-used for gating clocks and registers downstream where enablers are not available—even without needing a ... » read more

x86 Processor Road Map No Longer Just About Speed


By Ed Sperling The decades-old approach of powerful processors with ever-faster clock speeds is changing. Performance matters in some settings, but the real concern is adding more functionality within power budgets. The most pressing tradeoff is now performance vs. power, which has forced processor architects at AMD, Intel and IBM to take into account everything from application software to... » read more

Experts At The Table: Verification Strategies


By Ed Sperling System-Level Design sat down to discuss verification strategies and changes with Harry Foster, chief verification scientist at Mentor Graphics: Janick Bergeron, verification fellow at Synopsys; Pranav Ashar, CTO at Real Intent; Tom Anderson, vice president of marketing at Breker Verification Systems; and Raik Brinkmann, president and CEO of OneSpin Solutions. What follows are e... » read more

Diverging Viewpoints


By Ed Sperling The raw materials of semiconductor design include smart, well-trained people and money to fund good ideas from those people, whose backgrounds typically come from engineering, math, physics, computer science, materials science and sometimes even chemistry. While many experts, executives, and industry groups have been sounding the alarm in recent years about everything from la... » read more

Executive Briefing: Wally Rhines


By Ed Sperling System-Level Design, as part of its ongoing executive briefing series, sat down with Wally Rhines, Mentor Graphics' chairman and CEO, to talk about future problems, opportunities, and the gray areas that could go either way. What follows are excerpts of that conversation. SLD: Is the amount of time spent on verification increasing? Rhines: It depends on how you define who s... » read more
