The Week In Review: Design
By Ed Sperling - 17 Oct, 2014 - Comments: 0

Legal Mentor Graphics won a $36 million award plus royalties stemming from a patent infringement case involving EVE (Emulation & Verification Engineering), an emulation company that was purchased by Synopsys in 2012. A U.S. District Court jury in the District of Oregon found that EVE had directly and indirectly infringed on a 2001 patent entitled "Method and apparatus for gate-level simula... » read more

Design Rules Explode At New Nodes

Semiconductor Engineering sat down changing design rules with Sergey Shumarayev, senior director of custom IP design at Altera; Luigi Capodieci, R&D fellow at [getentity id="22819" comment="GlobalFoundries"]; Michael White, director of product marketing for Calibre Physical Verification at [getentity id="22017" e_name="Mentor Graphics"], and Coby Zelnik, CEO of [getentity id="22478" e_name=... » read more

The Impact Of 14nm Photomask Uncertainties On Computational Lithography Solutions
By Mentor, a Siemens Business - 16 Oct, 2014 - Comments: 0

Computational lithography solutions rely upon accurate process models to faithfully represent the imaging system output for a defined set of process and design inputs. These models, in turn, rely upon the accurate representation of multiple parameters associated with the scanner and the photomask. While certain system input variables, such as scanner numerical aperture, can be empirically tuned... » read more

Is Multi-Patterning Good for You?
By David Abercrombie - 16 Oct, 2014 - Comments: 0

I think we can all remember growing up and our parents making us take nasty-tasting medicines, or eat foods we didn’t like, or endure painful things like shots, all under the banner of “It is good for you!” We didn’t like it then, and we still don’t like it as adults. We would all prefer a way to lose weight while eating anything we want, or building strong muscles and aerobic health ... » read more

Blog Review: Oct. 15
By Ed Sperling - 15 Oct, 2014 - Comments: 0

Obesity makes your liver age faster, but you'll need a sophisticated biological clock to see that. Ansys' Bill Vandermark uncovers the top 5 engineering articles of the week. This one includes cyborg horses and an implanted prosthetic arm. Mentor's Colin Walls takes a look at "hard" and "soft" real time. It sounds like something out of a Salvador Dali painting. Rambus' Aharon Etengoff t... » read more

High-Level Gaps Emerge
By Ann Mutschler - 15 Oct, 2014 - Comments: 0

Semiconductor Engineering sat down to discuss the attributes of a high-level, front-end design flow with Bernard Murphy, CTO at [getentity id="22026" e_name="Atrenta"]; Leah Clark, associate technical director for digital video technology at Broadcom; Phil Bishop, vice president of the system level design system & verification group at [getentity id="22032" e_name="Cadence"]; and Jon McDon... » read more

Who Really Invented The Blue LED?
By Ed Sperling - 10 Oct, 2014 - Comments: 5

A dispute is simmering in the materials science community over the just-announced award of Nobel Prize in physics to three Japanese scientists, Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura. Two materials science Ph.D. students from Stanford claim they got there first—two decades earlier, in fact. There's even a U.S. patent filed by Stanford University to prove it. Akasaki and Amano wor... » read more

Embedded At DAC
By Anne Cirkel - 10 Oct, 2014 - Comments: 0

It seems to be one of DAC’s best kept secrets – right up there with what happened to Free Monday – that about 30% of the conference content is focused on embedded systems and software (ESS). The call for contributions is still open and I want to remind you that you can submit your research work in ESS to DAC. When Leon Stok of IBM was General Chair for the 48th DAC he started our embedded... » read more

Architecture Versus Silicon
By Ann Mutschler - 09 Oct, 2014 - Comments: 0

For many, if not most designs today, power is everything. Determining where power is being lost is critical to making sure the design is optimized. So where to begin? To this end, it is useful to go back to the fundamentals of what power is and what power consumption is, noted Paul Traynar, software architect at [getentity id="22021" comment="ANSYS/Apache"]. “Power is proportional to capac... » read more

Software Before Hardware?
By Ed Sperling - 09 Oct, 2014 - Comments: 0

The emphasis on battery life in wearable electronics, including always-on sensors, and the cost of powering and cooling racks of servers inside of data centers, are beginning to impact the formula for designing systems. Power is now a critical design element, but it's also one of the most stubborn to tackle. While ASICs, SoCs and FPGAs all have focused on being able to efficiently run softwa... » read more
