In Low Voltage Timing, the Center Cannot Hold

In Low Voltage Timing, the Center Cannot Hold
by Bernard Murphy on 01-25-2016 at 7:00 am

When I started discussing this topic with Isadore Katz, I was struggling to find a simple way to Image Removedexplain what he was telling me – that delay and variance calculations in STA tools are wrong at low voltage because the average (the center) of a timing distribution shifts from where you think it is going to be. He told me that… Read More


When Good Standards Get Lost – the UVM Register Model

When Good Standards Get Lost – the UVM Register Model
by Bernard Murphy on 01-20-2016 at 12:00 pm

Some time ago I wrote a DeepChip viewpoint on DVCON 2014 in which I praised a Image RemovedMentor paper “Of Camels and Committees”. The authors argued that while the UVM standards committee had a done a great job in the early releases, the 1.2 release was overloaded with nice-to-have features with questionable value for a standard,… Read More


Privacy – the Other Face of Security

Privacy – the Other Face of Security
by Bernard Murphy on 01-13-2016 at 7:00 am

Security gets a lot of tech press, privacy not so much. A lot of the problem is that whileImage Removed we each know intuitively what we mean by privacy, pinning down an actionable definition is surprisingly tricky, especially when we require that it not intrude in other ways on our rights. Privacy rights are not absolute (you don’t… Read More

There must be few less enviable jobs right now than Chairman and CEO of VW. Image RemovedAccording to Dr. Herbert Diess who has that dubious honor, the VW board debated whether they should attend CES this year and decided that on balance it was better to be visible, face the music and present their technology progress and visions than… Read More

My Choice for Coolest Thing from CES 2016 (Day 1)
by Bernard Murphy on 01-06-2016 at 4:00 pm

I’ll admit up-front I’m cheating. I’m writing this from the comfort of my home office Image Removedwithout having to go anywhere near the CES madness (I was there last year; 170,000 people packed into the center of Las Vegas, block-wrapping lines to get taxis, never again). I’m relying instead on the Wired preview of the first… Read More

More Medical Tech –Smart Bandages for Wound Management
by Bernard Murphy on 01-06-2016 at 12:00 pm

I have a bias (as you may have noticed) for solutions in a domain that take advantage of Image Removedtechnology but are developed within that domain. A recently example is intelligent bandages, developed at Massachusetts General Hospital, Harvard, Purdue and several other research centers. The purpose of such a bandage is to… Read More


A System Spin on IoT Security

A System Spin on IoT Security
by Bernard Murphy on 01-04-2016 at 4:00 pm

A lot of progress has been made in infrastructure to secure edge nodes in the IoT and to Image Removedsecure communications between edge nodes and gateways, all of which is good and necessary to block manifest evil, but it’s never enough. Perfect security is and always will be an asymptotic goal, so there should always be room for … Read More

The advantage of working with cache memory is the great boost in performance you canImage Removed get from working with a local high-speed copy of chunks of data from main memory. The downside is that you are messing with a copy; if another processor happens to be working in a similar area, there is a danger you can get out of sync when… Read More

Lighting Up The Cloud
by Bernard Murphy on 12-30-2015 at 7:00 am

In our rush to imagine a world populated with IoT devices, tech advances at the top endImage Removed of this ecosystem (the cloud) don’t seem to get much airtime. But this isn’t because they are limited to modest refinements. As one example, there is active technology development in connectivity around fiber-based communications… Read More

Auto Introspection
by Bernard Murphy on 12-20-2015 at 4:00 pm

It is an indictment of our irrationality that our cars are now more health-conscious than we Image Removedare. Increasingly safety-conscious readings of the ISO26262 standard now encourage that safety-critical electronics (anti-lock braking control for example) automatically self-test, not just at power-on but repeatedly… Read More
