I like to say that “you can’t ignore the physics any more” to point out that we have to worry about lots of physical effects that we never needed to consider. But “you can’t ignore the statistics any more” would be another good slogan. In the design world we like to pretend that the world is pass/fail. But manufacturing is actually a statistical… Read More

Webinar: IP integration methodology
The next Apache webinar is coming up on 21st July at 11am Pacific time on “IP integration methodology”.
This webinar will be conducted by Arvind Shanmugavel, Director Applications Engineering at Apache Design Solutions. Mr. Shanmugavel has been with Apache since 2007, supporting the RedHawk and Totem product … Read More
First low-power webinar: Ultra-low-power Methodology
The first of the low power webinars is coming up on July 19th at 11am Pacific time. The webinar will be conducted by Preeti Gupta, Sr. Technical Marketing Manager at Apache Design Solutions. Preeti has 10 years of experience in the exciting world of CMOS power. She has a Masters in Electrical Engineering from Indian Institute of technology,… Read More
And it’s Intel at 22nm but wait, Samsung slips ahead by 2nm…
Another announcement of interest, given all the discussion of Intel’s 22nm process around here, is that Samsung (along with ARM, Cadence and Synopsys) announced that they have taped out a 20nm ARM test-chip (using a Synopsys/Cadence flow).
An interesting wrinkle is that at 32nm and 28nm they used a gate-first process but… Read More
Cadence aquires Azuro
Cadence this morning announced that it has acquired Azuro. Azuro has become a leader in building the clock trees for high performance SoCs. A good rule of thumb is that the clock consumes 30% of the power in an SoC so optimizing it is really important. Terms were not disclosed.
The clock trees involve clock gating which can reduce clock… Read More
On-chip supercomputers, AMBA 4, Coore’s law
At DAC I talked with Mike Dimelow of ARM about the latest upcoming revision to the AMBA bus standards, AMBA 4. The standard gets an upgrade about every 5 years. The original ARM in 1992 ran at 10MIPS with a 20MHz clock. The first AMBA bus was a standard way to link the processor to memories (through the ARM system bus ASB) and to peripherals… Read More
Design for test at RTL
Design for test (DFT) imposes various restrictions on the design so that the test automation tools (automatic test pattern approaches such as scan, as well as built-in self-test approaches) will subsequently be able to generate the test program. For example, different test approaches impose constraints on clock generation… Read More
Low Power Webinar Series
At DAC 2011 in San Diego, Apache gave many product presentations. Of course not everyone could make DAC or could make all the presentations in which they were interested. So from mid-July until mid-August these presentations will be given as webinars. Details, and links for registration, are here on the Apache website.
The seminars… Read More
SOC Realization
There are some very interesting comments to the last entry on SoC Realization and how more and more chips are actually assembled out of IP. There was clearly a lot of discussion in this area at DAC, although most people (Atrenta being an exception) don’t use the term SoC Realization, presumably because it was originated by … Read More
Smartphones in the BRICs
The latest edition of GSA Forum has an article by Aveek Sarkar of Apache on system design for emerging market needs. The BRIC (Brazil, Russia, India, China) type countries are characterized by a small rich segment, a large and growing middle class and a large poor segment. One big trend is that smart phone use is expanding very fast.… Read More
