System Bits: Oct. 6
By Ann Mutschler - 06 Oct, 2015 - Comments: 0

Tiny graphene pores for sensors In fundamental work that will likely guide current and future graphene membrane design principles in years to come, MIT researchers have created tiny pores in single sheets of graphene that have an array of preferences and characteristics similar to those of ion channels in living cells, and which could be useful as sensors. The researchers pointed out that e... » read more

Light detector on a chip for portable sensors The invention by Vanderbilt University and Ohio University researchers of the first integrated circularly polarized light detector on a silicon chip could open the door for development of small, portable sensors to expand the use of polarized light in drug screening, surveillance, optical communications, quantum computing, and other applications. ... » read more

Can IP Integration Be Automated?
By Ann Mutschler - 24 Sep, 2015 - Comments: 1

What exactly does it mean to automate [getkc id="43" comment="IP"] integration? Ask four people in the industry and you’ll get four different answers. “The key issue is how you can assemble the hardware as quickly as you can out of pre-made pieces of IP,” said Charlie Janac, chairman and CEO of [getentity id="22674" e_name="Arteris"]. To Simon Rance, senior product manager in the ... » read more

ROI Not There Yet For SysML
By Ann Mutschler - 24 Sep, 2015 - Comments: 3

At some point down the road in the realm of system-level design, the Systems Modeling Language (SysML) dialect of the Unified Modeling Language (UML) standard may drive into semiconductor design. So far, however, a return on investment has not been established for its use. SysML is defined as a general-purpose visual modeling language for systems engineering applications, and it supports the... » read more

Scaling up production of thin electronic materials With potential application in future spintronics applications, among other things, a team led by MIT researchers have developed a way to make large sheets of molybdenum telluride (MoTe2) and other materials like graphene that hold promise for electronic, optical, and other high-tech applications. The team — which includes MIT postdoc Lin ... » read more

System Bits: Sept. 15

Cache-coherence innovation for thousand-core chips MIT researchers are getting ready to unveil what they say is the first fundamentally new approach to cache coherence in more than three decades. They reminded that in a modern, multicore chip, every processor core has its own small memory cache, where it stores frequently used data. The chip also has a larger, shared cache, which all the cores... » read more

Five Questions: Simon Davidmann
By Ann Mutschler - 14 Sep, 2015 - Comments: 0

Simon Davidmann, president and CEO of Imperas sat down with Semiconductor Engineering to discuss what software engineers want, software development challenges, software reuse, and software quality. SE: What do software engineers want today? Davidmann: We have a narrow view on it because we're coming out of the EDA industry and we're very close to the semiconductors and silicon. The bit th... » read more

Deciphering Performance Analysis
By Ann Mutschler - 10 Sep, 2015 - Comments: 1

Simulation traditionally has been the go-to technology for improving system performance, but practices are evolving and maturing because engineering teams need to be able to simulate in multiple domains and at at multiple levels of abstraction. In addition, they need to tune the level of [getkc id="11" kc_name="simulation"] they are using to what types of models they have available, and what ki... » read more

FPGA’s Role Expands
By Ann Mutschler - 10 Sep, 2015 - Comments: 1

For more than a decade FPGA vendors argued that FPGAs would become a viable alternative to ASICs, adding programmability along with the same kind of advances in performance and power that ASICs saw at each new process node. While that never played out as they expected, FPGAs nonetheless have carved out a formidable position in the semiconductor market. Generally speaking, FPGAs today are us... » read more

Performance Analysis On Dark Silicon
By Ann Mutschler - 10 Sep, 2015 - Comments: 0

It’s one thing to do performance analysis on the ‘light’ parts of an SoC design, but what about when most of the silicon is ‘dark?’ Jon McDonald, technical marketing engineer at Mentor Graphics stressed that modeling the effects of turning on and off sections of the silicon is an important part of creating an accurate representation of the system. “Our models support state-based... » read more
