Measuring Metastability

Measuring Metastability
by Jerry Cox on 01-24-2015 at 7:00 am

Measuring metastability is just 50 years old this year. In 1965 my colleague Tom Chaney took a sampling ‘scope picture of an ECL flip-flop going metastable. S. Lubkin had made mention of the phenomenon over a decade before that, but at that time most engineers were unaware of the phenomenon or did not believe it actually existed. … Read More


How Imagination tested the PowerVR Series6XT

How Imagination tested the PowerVR Series6XT
by Don Dingee on 01-23-2015 at 10:00 pm

We have been hearing for some time about the Synopsys HAPS-70 and how they have co-created the hardware and software architecture for FPGA-based prototyping with their customers. Now, we see details published by Synopsys on how they collaborated with Imagination on the design of the PowerVR Series6XT GPU.

The first thing to come… Read More


Will the Apple A9 Fall Flat?

Will the Apple A9 Fall Flat?
by Robert Maire on 01-23-2015 at 12:00 pm

Several months ago we had suggested that we were concerned that Apple’s A9 processor would wind up being 20nm planar (maybe 14nm planar) rather than the expected 14nm FinFET. As we are now under 9 months from a likely launch time for Apple’s next gen IPhone the timing for getting a 14nm FinFET processor on board the phoneRead More


How the iPhone Ended Nokia’s Reign!

How the iPhone Ended Nokia’s Reign!
by Daniel Nenni on 01-23-2015 at 7:30 am

The origin of ARM’s success in mobile phone space is largely traced to Symbian’s decision to exclusively support the ARM Instruction Set Architecture (ISA). This in turn was the consequence of a mid-1990s decision by Texas Instruments to use ARM in its mobile phone ASICs for Nokia, the driving force behind the inception of the Symbian… Read More


Windows on a TV

Windows on a TV
by Daniel Payne on 01-23-2015 at 12:00 am

This month I upgraded my TV at home with a 40″ LED set from Samsung, Denon AV receiver and Samsung Blu-ray player. Also being a Google fan I bought a Chromecast device.




At CES there were multiple announcements from Intel, and one that caught my eye was the Intel Compute Stick because it reminded me of the Google Chromecast device… Read More


Tracing Insight into Advanced Multicore Systems

Tracing Insight into Advanced Multicore Systems
by Pawan Fangaria on 01-22-2015 at 7:00 am

After knowing about the challenges involved in validating multicore systems and domains of system and application level tracing as explained by Don Dingee in his article “Tracing methods to multicore gladness” which is based on the first part of Mentor Embedded multicore whitepaper series, it’s time to take a deeper insight … Read More


Managing Semiconductor IP

Managing Semiconductor IP
by Daniel Payne on 01-21-2015 at 5:00 pm

SemiWiki blogger Eric Esteve does an excellent job writing about all of the semiconductor IP available, and the popularity of IP is only growing more each year. Here’s a projection from IBS about semiconductor IP showing revenues of $4.7B by 2020:

Analyst Gary Smith divides IP into three broad categories: Functional, Foundation… Read More


Analyzing Power Nets

Analyzing Power Nets
by Paul McLellan on 01-21-2015 at 7:00 am

One of the big challenges in a modern SoC is doing an accurate analysis of the power nets. Different layers of metal have very different resistance characteristics (since they vary so much in width and height). Even vias can cause problems due to high resistance. Typically power is distributed globally on high-level metal layers,… Read More


Not All RTL Synthesis Approaches are the Same

Not All RTL Synthesis Approaches are the Same
by Daniel Payne on 01-20-2015 at 7:00 pm

My first experience with logic synthesis was at Silicon Compilers in the late 1980s using a tool called Genesil. Process technology since that time has moved from 3 um down to 20 nm, so there are new challenges for RTL synthesis. Today you can find logic synthesis tools being offered by the big three in EDA: Synopsys, Cadence, MentorRead More


Methodics Access Controls

Methodics Access Controls
by Paul McLellan on 01-20-2015 at 7:00 am

My PhD thesis is titled The Design of a Network Filing System. Yes, that was a research topic back then (and yes, we did call them filing systems not file-systems). One big chapter was on access controls. There are several problems with designing an access control system:

  • it needs to be possible to implement it efficiently
  • it needs
