Rapid Distortion Analysis For Intercept Point Calculations


Distortion effects have an important impact on the performance of RF circuits, including mixers, low-noise amplifiers (LNAs) and power amplifiers (PAs). At high frequencies, particularly with narrowband circuits, it is common to characterize the distortion produced by circuit nonlinearities in terms of an intercept point (IPn). Under small signal input conditions, from where intercept points ar... » read more

Experts At The Table: Yield And Reliability Issues With Integrating IP


Semiconductor Engineering sat down to discuss the impact of integrating IP in complex SoCs with Juan Rey, senior director of engineering at Mentor Graphics; Kevin Yee, product marketing director for Cadence’s SoC Realization Group; and Mike Gianfagna, vice president of marketing at eSilicon. What follows are excerpts of that conversation. SE: As an industry we’ve got a pretty good grasp ... » read more

A Perspective On Open Process Specification


It is the job of the Process Design Kit (PDK) engineers to deliver a high-quality PDK that properly represents the process requirements and constraints and supports the design flows used by their customers. The PDK engineer takes multiple inputs describing the process and the devices and circuitry in the process and generates the output in the form of OpenAccess technology libraries (techDB), d... » read more

The Week In Review: System-Level Design


India's reliance on technology has created a huge demand for software in the country. IDC expects the market for enterprise software in India to grow 19%, and the market for collaborative applications to grow 13.5%. Growth is continuing across all business markets, turning India into a huge consumer of software rather than just a creator. The enterprise software market in India is dominated by ... » read more

Defining The Next Standard Cell


Synopsys, Intel and IBM all contributed technology to Si2 to create a standard version of parameterized cells, or PCells, for mixed-signal designs. The move is an attempt to smooth out design incompatibilities using Synopsys and Cadence technology. Cadence is the clear market leader in this space. But as more technology is developed using different vendors'  tools for integration in complex... » read more

Blog Review: Jan. 22


Mentor’s Anil Khanna believes Nest’s approach should be incorporated into the entire power grid. The ramifications of that are interesting to ponder. Speaking of Nest, Cadence’s Brian Fuller looks at the implications of the $3.2 billion acquisition of the company by Google. Will Google get it right? Maybe. Synopsys’ Richard Solomon has come up with a new definition for New Year’... » read more

The Next Big Threat: Power And Performance


In the shiny world of consumer electronics and powerful computers, taking a grinder to the outside of a package may sound more like safecracking than sophisticated electronic code hacking. The reality is there is more in common than most semiconductor companies would like to admit, and the starting point often is just as crude. To no small extent, systems on chip have become miniature safes.... » read more

Week In Review: System-Level Design


Cadence rolled out a new version of its functional verification platform, greatly improving performance and updating it to deal with the big increases in third-party and re-used IP in designs. For IP and block verification, the company said it increased formal analysis performance by up to 20% and simulation by up to 10 times. The debugger also reduces the database size by 10 times and the time... » read more

Which IP Is Better?


As the amount of third-party and re-used IP in a semiconductor increases, so do the number of questions about which possible IP choices perform better, use the least power, or work best with other components. So far, there is no simple way to make that choice. In most cases, this is simply splitting hairs. For all the IP that goes into designs, the bulk of it is chosen based on how often has... » read more

Mostly Accurate Computing


“Approximate computing” is a new concept in computers, allowing them to perform calculations for certain tasks that don’t require perfect accuracy with the goal of improving efficiency and reducing energy consumption. But do the concepts apply when it comes to managing power? And is there a philosophical approach when it comes to thinking about power management? To a large extent, that... » read more
