Big Data and Power Integrity: Drilling Down

Big Data and Power Integrity: Drilling Down
by Bernard Murphy on 08-21-2017 at 7:00 am

I’ve written before about how Ansys applies big data analytics and elastic compute in support of power integrity and other types of analysis. A good example of the need follows this reasoning: Advanced designs today require advanced semiconductor processes – 16nm and below. Designs at these processes run at low voltages, much… Read More


Webinar: Ansys on Multi-Physics PDN Optimization for 16/7nm

Webinar: Ansys on Multi-Physics PDN Optimization for 16/7nm
by Bernard Murphy on 07-22-2017 at 12:00 pm

On the off-chance you missed my previous pieces on this topic, at these dimensions conventional margin-based analysis becomes unreasonably pessimistic and it is necessary to analyze multiple dimensions together. People who build aircraft engines, turbines and other complex systems have known this for quite a long time. You… Read More


Why Ansys bought CLKDA

Why Ansys bought CLKDA
by Bernard Murphy on 07-18-2017 at 7:00 am

Skipping over debates about what exactly changed hands in this transaction, what interests me is the technical motivation since I’m familiar with solutions at both companies. Of course, I can construct my own high-level rationalization, but I wanted to hear from the insiders, so I pestered Vic Kulkarni (VP and Chief Strategist)… Read More


Margin Call

Margin Call
by Bernard Murphy on 06-04-2017 at 7:00 am

A year ago, I wrote about Ansys’ intro of Big Data methods into the world of power integrity analysis. The motivation behind this advance was introduced in another blog, questioning how far margin-based approaches to complex multi-dimensional analyses could go. An accurate analysis of power integrity in a complex chip should… Read More


Simulating ADAS

Simulating ADAS
by Bernard Murphy on 05-04-2017 at 7:00 am

Simulation is a broad technique spanning certainly digital logic and circuit simulation but also methods beyond these which are particularly relevant to ADAS design. In fact, much of the design of full ADAS systems begins and ends with these types of modeling. This is in part due to the need fully validate integrity and reliability… Read More


Webinar: Chip-Package-System Design for ADAS

Webinar: Chip-Package-System Design for ADAS
by Bernard Murphy on 04-10-2017 at 7:00 am

When thinking of ADAS from an embedded system perspective, it is tempting to imagine that system can be designed to some agreed margins without needing to worry too much about the details of the car environment and larger environment outside the car. But that’s no longer practical (or acceptable) for ADAS or autonomous systems.… Read More


Power Management Beyond the Edge

Power Management Beyond the Edge
by Bernard Murphy on 01-25-2017 at 7:00 am

Power in IoT edge devices gets a lot of press around how to make devices last for years on a single battery charge, significantly through “dark silicon” – turning on only briefly to perform some measurement and shoot off a wireless transmission before turning off again. But we tend to forget that the infrastructure to support… Read More


Executive Interview: Vic Kulkarni of ANSYS

Executive Interview: Vic Kulkarni of ANSYS
by Daniel Nenni on 11-07-2016 at 7:00 am

Having known Vic for many years, it is always great to spend time with him and catch up on what is happening inside the semiconductor ecosystem. As Senior Vice President and General Manager, RTL Power Business, at ANSYS in Silicon Valley, Vic spends a lot of time in the field with customers, partners, and at industry events so he has… Read More


Low Power Design – a Server Perspective (Webinar)

Low Power Design – a Server Perspective (Webinar)
by Bernard Murphy on 09-21-2016 at 7:00 am

Most of what you have read about design for low power has probably focused on mobile devices where power consumption constraints tend to outweigh performance objectives. These devices use aggressive power switching strategies, based on the reasonable assumption that parts or all of the device can be powered down at any given … Read More


Integrity and Reliability in Analog and Mixed-Signal

Integrity and Reliability in Analog and Mixed-Signal
by Bernard Murphy on 07-18-2016 at 1:30 pm

In the largest and fastest growing categories in electronics – mobile, IoT and automotive – analog is playing an increasingly important role. It’s important in delivering high integrity power and critical signals to the design though LDO regulators and PLLs, in managing high speed interfaces like DDR and SERDES, in interfacing… Read More
