In his Wednesday keynote, Singer warned that today's SoC has become "a system of systems, not just a system". He proposed five principles for the EDA industry to adopt the following: (1) the user model needs to be applied to designs; (2) apply system world capabilities to the silicon world; (3) optimisation needs to be across ICs, systems and software; (4) be agile and learn from iterations as in the software world; and (5) hardware IP should come with firmware and drivers, and verification suites.

Singer called for EDA to accept "new challenges with a sense of urgency" lest they miss their value-creating opportunities which will manifest in five to ten years.

In her keynote on Tuesday Freescale executive Lisa Sue made her pitch for bringing software together into the chip development tent in order to create the needed value for designers.

Meanwhile, peripheral to EDA developments there were a few interesting technical papers on diverse topics.

Researchers at Seoul National University together with University of Southern California at DAC introduced the first OLED power saving technique that does not result in a significant degradation in the colour and luminance values of the displayed image.

Their technique is based on dynamic driving voltage scaling of the OLED panel. Although the proposed DVS technique may degrade luminance of the panel, the panel luminance can be restored with appropriate image compensation. Consequently, power is saved on the OLED display panel with only minor changes in the colour and luminance of the image, according to their paper.

This technique is similar to dynamic backlight scaling of LCDs, but is based on the unique characteristics of the OLED drivers. Experimental results show that the proposed OLED DVS with image compensation technique saves up to 52.5 per cent of the OLED power while keeping the same human-perceived image quality for the standard "Lena" multi-coloured image, according to the researchers.

Steve Wozniak, chief scientist at Fusion-io, in the Monday keynote welcomed his former Apple co-founder's introduction of iCloud for the consumer on the same day as Wozniak's fireside chat keynote at DAC.

"Steve Jobs continues his quest "to hide the technology from the consumer," by enticing Apple device users to give up their data to Apple's "cloud" external storage. "I, on the other hand, love math, and to see how things work. I can go to sleep thinking of a problem and wake up with the answer," says Wozniak.
