Noise Abatement
By Brian Bailey - 12 Oct, 2017 - Comments: 0

[getkc id="285" kc_name="Noise"] is a fact of life. Almost everything we do creates noise as a by-product and quite often what is a signal to one party is noise to another. Noise cannot be eliminated. It must be managed. But is noise becoming a larger issue in chips as the technology nodes get smaller and packaging becomes more complex? For some, the answer is a very strong yes, while for ot... » read more

Improving Yield, Reliability With Data
By Ann Mutschler - 11 Oct, 2017 - Comments: 0

Big data techniques for sorting through massive amounts of data to identify aberrations are beginning to find a home in semiconductor manufacturing, fueled by new requirements in safety-critical markets such as automotive as well as the rising price of packaged chips in smartphones. Outlier detection—the process of finding data points outside the normal distribution—isn't a new idea. It ... » read more

Starting Point Is Changing For Designs
By Ed Sperling - 04 Oct, 2017 - Comments: 0

The starting point for semiconductor designs is shifting. What used to be a fairly straightforward exercise of choosing a processor based on power or performance, followed by how much on-chip versus off-chip memory is required, has become much more complicated. This is partly due to an emphasis on application-specific hardware and software solutions for markets that either never existed befo... » read more

Prototypes Proliferate
By Brian Bailey - 02 Oct, 2017 - Comments: 0

Hardware prototyping and [getkc id="30" kc_name="emulation"] have been two sides of the same coin ever since the [gettech id="31071" comment="FPGA"] became a commercial success. Early emulators were all built from FPGAs, and most were used in-circuit, much like prototypes are today. More recently, emulation has become a major piece of the [getkc id="10" kc_name="verification"] flow, to the poin... » read more

M&A Imagination will sell its MIPS business to Tallwood, a California-based venture capital firm, for $65m in cash. The sale is expected to close in October. The rest of Imagination is slated to be sold to Canyon Bridge for £550 million in cash (~$740 million), a deal dependent on the MIPS sale. The Chinese-backed investment firm has featured recently in the news for its attempted purchas... » read more

System Design And Verification Challenges: Are They On- Or Off-Chip?
By Frank Schirrmeister - 28 Sep, 2017 - Comments: 0

What are the next natural items for mobile devices to be integrated? From 2002 to today, previously separate items (like GPS, cameras and keyboards) have been integrated into the phone. They caused a frenzy of integration within systems on chips. Now we have the Internet of Things (IoT) adding a trillion devices to the picture. Which ones are to be integrated, if any? What does all this mean fo... » read more

System Coverage Undefined
By Brian Bailey - 28 Sep, 2017 - Comments: 1

When is a design ready to be taped out? That has been one of the toughest questions to confront every design team, and it's the one verification engineers lose sleep over. Exhaustive [getkc id="56" kc_name="coverage"] has not been possible since the 1980s. Several metrics and methodologies have been defined to help answer the question and to raise confidence that important aspects of a block... » read more
