A Brief History of Semiconductors: the Foundry Transition

A Brief History of Semiconductors: the Foundry Transition

A modern fab can cost as much as $10B dollars. That’s billion with a B. Since it has a lifetime of perhaps 5 years, owning a fab costs around $50 per second and that’s before you buy any silicon or chemicals or design any chips. Obviously anyone owning a fab had better be planning on making and selling a lot of chips if they are going to make… Read More


3D Memories

3D Memories
by Paul McLellan on 09-02-2012 at 4:42 pm

At DesignCon earlier this year, Tim Hollis of Micron gave an interesting presentation on 3D memories. For sure the first applications of true 3D chips are going to be stacks of memory die and memory on logic. The gains from high bandwidth access to the memory and the physically closer distance from memory to processor are huge.

Micron… Read More


The Need for OASIS in Post-layout IC Databases

The Need for OASIS in Post-layout IC Databases
by Daniel Payne on 08-31-2012 at 7:20 pm

OASIS is a hierarchical IC file format used for IC designs that is gradually replacing GDS II throughout the mask data stages. The compelling reason for using OASIS has always been the reduction of file size, and speed up of processing times through the use of hierarchy and fewer translation steps.

At the 45nm node an actual M1 layer… Read More


TSMC 28nm Update Q3 2012!

TSMC 28nm Update Q3 2012!
by Daniel Nenni on 08-28-2012 at 7:30 pm

Reports out of Taiwan (I’m in Hsinchu this week) have TSMC more than doubling 28nm wafer output in Q3 2012 due to yield improvements and capacity increases while only spending $3.6B of the $8.5B forecasted CAPEX! Current estimates have TSMC 28nm capacity at 100,000 300mm wafers (+/- 10%) per month versus 25,000 wafers reported… Read More


Assertion Synthesis

Assertion Synthesis

In June, Atrenta acquired NextOp, the leader in assertion synthesis. So what is it?

Depending on who you ask, verification is a huge fraction, 60-80%, of the cost of an SoC design, so obviously any technology that can reduce the cost of verification has a major impact on the overall cost and schedule of a design. At a high-level, verification… Read More


Power, Signal, Thermal and EMI signoff

Power, Signal, Thermal and EMI signoff
by Paul McLellan on 08-28-2012 at 1:55 pm

Increasingly the challenge with SoCs, especially for mobile, is not getting the performance high enough but doing so in a power-efficient manner. Handheld devices running multiple apps need high-speed processors that consume extremely low levels of power both in operating and standby modes. In the server farm, the limit is … Read More


Apple’s Victory Will Re-Shuffle the Semi Industry

Apple’s Victory Will Re-Shuffle the Semi Industry
by Ed McKernan on 08-27-2012 at 2:00 pm

Apple’s legal victory over Samsung has been analyzed in thousands of articles and TWEETs since last Friday’s announcement and surely more will follow. Most of the commentary has focused on the first order impact to handset manufacturers. It is not entirely clear how it will all settle but there are sure to be secondary ramifications… Read More


A Brief History of ASIC, part II

A Brief History of ASIC, part II
by Paul McLellan on 08-23-2012 at 8:00 pm

All semiconductor companies were caught up in ASIC in some way or another because of the basic economics. Semiconductor technology allowed medium sized designs to be done, and medium sized designs were pretty much all different. The technology didn’t yet allow whole systems to be put on a single chip. So semiconductor companies… Read More


Cadence at 20nm

Cadence at 20nm
by Paul McLellan on 08-21-2012 at 8:10 pm

Cadence has a new white paper out about the changes in IC design that are coming at 20nm. One thing is very clear: 20nm is not simply “more of the same”. All design, from basic standard cells up to huge SoCs has several new challenges to go along with all the old ones that we had at 45nm and 28nm.

I should emphasize that the paper… Read More


A Brief History of ASIC, part I

A Brief History of ASIC, part I
by Paul McLellan on 08-21-2012 at 7:00 pm

In the early 1980s the ideas and infrastructure for what would eventually be called ASIC started to come together. Semiconductor technology had reached the point that a useful number of transistors could be put onto a chip. But unlike earlier, when a chip only held a few transistors and thus could be used to create basic generic building… Read More
