When people discuss capabilities of leading edge process nodes they tend to focus on digital logic. Microprocessors in particular. But a process requires more than just digital logic and standard cells to be successful. In particular, pretty much every SoC contains a lot of memory so the memory capabilities of a process are important.… Read More


A Brief History of Andes Technology

A Brief History of Andes Technology
by Paul McLellan on 01-06-2014 at 4:47 pm

I like to call Andes Technology the biggest microprocessor IP company you’ve never heard of. I wrote about themback in October when I sat down with them during the Linley Microprocessor Conference. Part of the reason you have never heard of them is that they are based in Taiwan and most of their business is in Taiwan and China.… Read More


GlobalFoundries Has a New CEO

GlobalFoundries Has a New CEO
by Paul McLellan on 01-06-2014 at 4:07 pm

Sanjay Jha is taking over as CEO of GlobalFoundries. His background is in mobile. He was at Qualcomm in the early part of his career and was COO from 2006 to 2008 before going to be co-CEO of Motorola and then, when the company was split, CEO of Motorola Mobility. That was acquired by Google and he stepped down after the acquisition closed.… Read More


Imagination’s New GPU Cores

Imagination’s New GPU Cores
by Paul McLellan on 01-06-2014 at 9:00 am

This morning Imagination announced their latest GPU cores, including the world’s smallest fully-featured OpenGL ES3.0/OpenCL GPU core. More on that below. And it is the Internet…and graphics…so cats. Graphically rendered cats.

The first core is a a high end core new generation PowerVR Series6XT architecture… Read More


Structured Asic Dies…Again

Structured Asic Dies…Again
by Paul McLellan on 01-04-2014 at 11:53 pm


There has always been a dream that you could do a design in a cheap easy to design technology and then, if the design was a hit, press a button and instantly move it into a cheaper unit-price high volume design. When I was at VLSI in the 1980s we had approaches to make it easy to move gate arrays (relatively large die area) into standard cells… Read More


New Frontiers in Scan Diagnosis

New Frontiers in Scan Diagnosis
by Paul McLellan on 01-03-2014 at 8:10 pm

As we move down into more and more advanced process nodes, the rules of how we test designs are having to change. One big challenge is the requirement to zoom in and fix problems by doing root cause analysis on test data alone, along with the rest of the design data such as detailed layout, optical proximity correction and so on. But without… Read More


NoC, NoC: Your Chip May Be Under Attack

NoC, NoC: Your Chip May Be Under Attack
by Paul McLellan on 01-03-2014 at 12:37 pm

SoCs face a lot of issues related to security and the Network-on-Chip (NoC) is in a good position to facilitate system-wide services. SoCs are now so complex that one of the challenges is to make sure that the chip does what it is meant to do and doesn’t do what it isn’t meant to do. Just as in software, security used to be … Read More


ClioSoft at Arasan

ClioSoft at Arasan
by Paul McLellan on 01-01-2014 at 8:00 am

Arasan recently adopted ClioSoft for data management (DM) for design and development of Arasan’s Silicon IP products. This morning I talked to Erik Peterson, Senior CAD and Verification Engineer AMS Design about their experiences bringing up ClioSoft.

Data management infrastructure is critical with engineering projects… Read More


2013 Awards, and the Winner is…Power

2013 Awards, and the Winner is…Power
by Paul McLellan on 01-01-2014 at 8:00 am

Of all the things that designers have to worry about in the power-performance-area (PPA) equation, the most challenging is power. SoCs have reached a point that we can put a lot of stuff on them, but if we are not careful we cannot light it all up at once. Dark silicon, where we put subsystems on a chip but then don’t have enough … Read More


Macro Placement Challenges

Macro Placement Challenges
by Paul McLellan on 12-27-2013 at 7:28 pm

One of the challenges of physical design of a modern SoC is that of macro placement. Back when a design just had a few macros then the flooplanning could be handled largely manually. But modern SoCs suffer from a number of problems. A new white paper from Mentor covers Olympus-SOCs features to address these issues:

  • As we move to smaller
