40nm to 28nm Migration Success Story

40nm to 28nm Migration Success Story
by Paul McLellan on 05-08-2011 at 4:00 pm

The problem:To move dual-port SRAM library and macros from a 40nm process to a 28nm process. In addition to all the changes between two different foundry processes, the 28nm rules are disruptive and incompatible with the previous rules. The memory corecells (foundry-specific) would also need to be completely replaced.

Intel’s 22nm Process. Atom, ARM, Apple
by Paul McLellan on 05-05-2011 at 9:52 am

Intel had a big press event yesterday at which they announced details of their 22nm process. In a change from their current processes, it goes with a vertical gate. In fact 3 gates which gives them much better control of leakage through transistors that are switched off, along with more transmission through the on transistors. They… Read More

Chip Power Models
by Paul McLellan on 05-04-2011 at 4:21 pm

As the complexity of the chip-package-system (CPS) interactions has increased, the tradeoffs in doing a power and noise analysis has had to gradually increase. As is so often the case in semiconductor designs, issues first arise as second-order effects that can largely be ignored but each process node makes the problem worse … Read More


Apache at DAC

DAC is less than a month away, June 6-8th for the tradeshow, longer depending on what other events you might also be attending. Apache is in booth 2448 (marked in red on the DAC floorplan map.

Many of the presentations at the Apache booth will be customers (such as ARM, Xilinx, ST Ericsson, GlobalFoundries and TSMC) discussing various… Read More

Introduction
Today Cadence announced at the Embedded Systems Conference something of interest to systems designers.

What’s New?
The Rapid Prototyping Platform and Virtual System Platform are what’s new, and they intend to enable and automate concurrent hardware and software development. I can remember Mentor… Read More

Although there has been always a strong relationship between Kilopass and Chartered Semiconductor, this relationship has been even enhanced after the acquisition of Chartered by GLOBALFOUNDRIES, allowing Kilopass’s customers to integrate NVM IP on advanced technology nodes, down to 40nm or even 28nm in the near future.

Graphical DRC vs Text-based DRC

Graphical DRC vs Text-based DRC
by Daniel Payne on 05-01-2011 at 11:42 am

Introduction
IC designs go through a layout process and then a verification of that layout to determine if the layout layer width and spacing rules conform to a set of manufacturing design rules. Adhering to the layout rules will ensure that your chip has acceptable yields.

At the 28nm node a typical DRC (Design Rule Check) deck will… Read More


Mentor 2 : Carl Icahn 0

Mentor 2 : Carl Icahn 0
by Daniel Nenni on 05-01-2011 at 9:46 am

The corporate raiders are still throwing rocks at Mentor Graphics. I have followed this reality show VERY closely and find their latest assault seriously counterproductive. Disinformation is common in EDA but I expected more from Carl Icahn and the Raiderettes. They are quite the drama queens. Here is a billion dollar question:… Read More


TSMC Conference Call is a 6.5 on the Richter Scale

TSMC Conference Call is a 6.5 on the Richter Scale
by Daniel Nenni on 04-28-2011 at 12:17 am

TSMC continues to drive the economic recovery with impressive Q1 numbers and an even more impressive Q2 and Q3 outlook. TSMC is my economic bellwether due to its diverse customer base and shear volume of consumer electronics silicon. The big surprise in the 1 hour Q1 conference call is a new Giga Fab (#15) ground breaking this year… Read More

Ivo Bolsens of Xilinx and Crossover Designs
by Paul McLellan on 04-27-2011 at 4:14 pm

I was at Mentor’s u2u (user group) meeting and one of the keynotes was by Ivo Bolsens of Xilinx. The other was by Wally Rhines and is summarized here.

Ivo started off talking analogizing SoCs as the sports-cars of the industry (fast but expensive), and FPGAs as the station wagons (not cool). In fact he even said that when Xilinx… Read More
