Getting Low Power Design Right in Mixed Signal Designs

Getting Low Power Design Right in Mixed Signal Designs
by Bernard Murphy on 05-12-2016 at 4:00 pm

Mixed-signal design creates all sorts of interesting problems for implementation and verification flows, particularly when it comes to design for low power. We tend to think of mixed-signal as a few blocks like PLLs, ADCs and PHYs on the periphery of the design. Constrain and verify the digital power requirements up to analog … Read More

Deep learning based on neural nets is most commonly thought of as a very promising approach to scene recognition, text recognition and similar areas. Now there is increasing interest in applying this technology to security objectives. There were a number of papers on this topic in a 2015 BlackHat conference and there are several… Read More


Neural nets for Qualcomm Snapdragon

Neural nets for Qualcomm Snapdragon
by Bernard Murphy on 05-06-2016 at 12:00 pm

Neural nets are hot these days. In this forum certainly you can’t swing a cat without hitting multiple articles on the topic – I’ve written some myself. For me there are two reasons for this interest. First, neural nets are amazingly successful at what they do, for example in image recognition where they can beat… Read More

Ecosystem Partnership for Effective Network Hardware Design
by Bernard Murphy on 04-29-2016 at 12:00 pm

When you’re designing a hardware solution to plug into what is arguably the most complex system of all – the Internet – you can’t get away with a little fake traffic to test whether your box is going to do all the right things at the right performance. You have to model realistic voice, video, data and wireless traffic in… Read More


Software-Driven Verification Drives Tight Links between Emulation and Prototyping

Software-Driven Verification Drives Tight Links between Emulation and Prototyping
by Bernard Murphy on 04-28-2016 at 12:00 pm

I’ve mentioned many times what has become a very common theme in SoC and system verification – it has to be driven by the software because any concept of exhaustively verifying “everything” is neither feasible nor meaningful. Emulation has become a critical component of this flow in validating and regressing… Read More


Metric-Driven Verification for System Signoff

Metric-Driven Verification for System Signoff
by Bernard Murphy on 04-27-2016 at 12:00 pm

Everyone knows that verification is hard and is consuming an increasing percentage of verification time and effort. And everyone should know that system-level verification (SoC plus at least some software and maybe models for other components on a board) is even harder—which is why you see hand-wringing over how incompletely… Read More

SpyGlass DFT ADV accelerates test closure – Xilinx and Synopsys webinar
by Bernard Murphy on 04-26-2016 at 12:00 pm

Fed up with ECOing your way out of test problems? You might want to register for this webinar.When you’re building monster SoC FPGAs, you have all the same problems you have with any other SoC. That includes getting to very high test coverage as quickly as you can with a design targeted to the most advanced processes. We’re not just … Read More


Quantum Code-Cracking Takes Another Hit: Lattice-based Cryptography

Quantum Code-Cracking Takes Another Hit: Lattice-based Cryptography
by Bernard Murphy on 04-24-2016 at 12:00 pm

Public-key crypto-systems rely these days on approaches founded in mathematical methods which are provably hard to crack. The easiest to understand requires factorization of a key based on the product of two large prime numbers. Much has been made recently of the ability of quantum computers to crack this style of encryption.… Read More


Digital Design Trends – A Cadence Perspective

Digital Design Trends – A Cadence Perspective
by Bernard Murphy on 04-21-2016 at 7:00 am

I talked with Paul Cunningham (VP front-end digital R&D) at CDNLive recently to get a Cadence perspective on digital design trends. He sees needs from traditional semiconductor companies evolving as usual, with disruption here and there from consolidation. But on the system side there is explosion in demand – for wearables,… Read More

More on the Practical Uses of Automation
by Bernard Murphy on 04-18-2016 at 12:00 pm

There’s a good article in the March issue of the Communications of the ACM which follows a theme I commented in my “One, Two Many” post. But the CACM article has a better title: “Automation should be like Iron Man, not Ultron”.

For anyone who hasn’t seen the movies, Iron Man is a man (Tony Stark)… Read More
