Cadence 3D Methodology

Cadence 3D Methodology
by Paul McLellan on 12-28-2012 at 8:20 pm

A couple of weeks ago was the 3D Architectures for Semiconductor Integration and Packagingconference in Redwood City. Cadence presented the changes that they have been making to their tool flow to enabled 2.5D (interposer-based) and true 3D TSV-based designs. You know what TSV stands for by now right? Through-silicon-via, … Read More


3D Architectures for Semiconductor Integration and Packaging

3D Architectures for Semiconductor Integration and Packaging
by Paul McLellan on 12-10-2012 at 4:00 am

There is obviously a lot going on in 3D IC these days. And I don’t mean at the micro level of FinFETs which is also a way of going vertical. I mean through-silicon-via (TSV) based approaches for either stacking die or putting them on an interposer. Increasingly the question is no longer if this technology will be viable (there… Read More


Dimensions of Electronic Design Seminars

Dimensions of Electronic Design Seminars
by Paul McLellan on 10-02-2012 at 6:37 pm

ANSYS and Apache are putting on a new series of seminars about designing future electronic systems. These are only getting more complex, of course, cramming more and more functionality into smaller portable devices with good battery life (and not getting too hot), integrating multiple antennas into a single platform, and TSV-based… 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


3D Thermal Analysis

3D Thermal Analysis
by Paul McLellan on 07-17-2012 at 11:32 am

Matt Elmore of ANSYS/Apache has an interesting blog posting about thermal analysis in 3D integrated circuits. With both technical and economic challenges at process nodes as we push below 28nm, increasingly product groups are looking towards through-silicon-via (TSV) based approaches as a way of keeping Moore’s law… Read More


Cadence at Semicon West Next Week: 2.5D and 3D

Cadence at Semicon West Next Week: 2.5D and 3D
by Paul McLellan on 07-05-2012 at 5:32 pm

Next week it is Semicon West in the Moscone Center from Tuesday to Thursday, July 10-12th. Cadence will be on a panel session during a session entitled The 2.5D and 3D packaging landscape for 2015 and beyond. This starts with 3 short keynotes:

  • 1.10pm to 1.25pm: Dr John Xie of Altera on Interposer integration through chip on wafer on

One Billion Transistor IC Layout Editing

One Billion Transistor IC Layout Editing
by Daniel Payne on 06-11-2012 at 6:33 pm

There are only a handful of billion transistor IC designs in existence today, so when an EDA company touts 1 trillion transistor IC layout editing then I take notice. This year at DAC I met with Katherine Hayes and Karen Mangum of Micro Magic to get an update on their IC layout tools.… Read More


EDPS: 3D ICs, part I

EDPS: 3D ICs, part I
by Paul McLellan on 04-10-2012 at 10:00 pm

The second day (more like a half-day) of EDPS was devoted to 3D ICs. There was a lot of information, too much to summarize in a few hundred words. The keynote was by Riko Radojcic of Qualcomm, who has been a sort of one-man-band attempting to drive the EDA and manufacturing industries towards 3D. Of course it helps if you don’t … Read More


Synopsys: now in 3D

Synopsys: now in 3D
by Paul McLellan on 03-26-2012 at 8:00 am

And no red and green glasses required.

I remember the first time I heard about a Through Silicon Via (TSV), punching a hole through the entire wafer to make an electrical connection at the back, like we do all the time in printed circuit boards with through plated holes. I thought someone was trying one on and trying to make me look a fool.… Read More


3D Standards

3D Standards
by Paul McLellan on 02-01-2012 at 5:06 pm

At DesignCon this week there was a panel on 3D standards organized by Si2. I also talked to Aveek Sarkar of Apache (a subsidiary of Ansys) who is one of the founding member companies of the Si2 Open3D Technical Advisory Board (TAB), along with Atrenta, Cadence, Fraunhofer Institute, Global Foundries, Intel, Invarian, Mentor, Qualcomm,… Read More
