I spoke with Todd Westerhoff of SiSoft about their new Virtual Prototype Analysis that can simulate large systems with thousands of serial links at DesignCon 2012. You can see the video interview here and below is a short description and link to a technical paper that described the analysis of such a large system.
While not long ago systems had only several serial links, it’s now becoming common for systems to include hundreds – and even thousands – of such links. This paper describes the development and analysis of a large system with thousands of serial links. Due to the system’s size and complexity, the design team invested in a multi-year effort to build and qualify a virtual environment capable of both verifying connectivity and simulating any and all of the channels. Problematic channels with incomplete system-level connections, poor eye openings, or high BER are quickly identified. Performance limiters such as inherent discontinuities (and their associated resonances), and Tx/Rx equalization imbalance are found and examined in detail. The virtual system is also used to guide design choices such as layer stacking, via construction, back-drilling, and trace/connector impedances. Processes to optimize and select equalization choices are also described.
Welcome to the new “EDACafe Weekly.” Every Monday you will be receiving a summary of the previous weeks EDACafe blog postings, including our featured writer Peggy Aycinena. There will be postings from my blogs: Video Roundup, The Dominion of Design and IP Showcase, that cover the various facets of creating new electronic designs. And of course, all the other blog contributors from the past week.
We look forward to hearing your comments about the new format….and let me know if you would like to start a blog on EDACafe.
EDA companies often address hardware/software co-design from a hardware point of view. ie, how can software developers run their software on this representation of a chip that was designed on our tools. This viewpoint often overlooks the real concerns of software developers. Today, since software is the fastest growing and the largest engineering content of a SoC/ASIC design, it is time for the EDA industry to understand the needs and concerns of the software industry. This panel attempts to address these needs and concerns.
The panel is organized by Paul McLellan, an EDA industry: guru, veteran, analyst and author. He has extensive experience in IC design, software development and system virtualization . In particular he was VP marketing at VaST (since acquired by Synopsys) and Virtutech (since acquired by Wind River/Intel). The panelists include software engineering managers who are responsible for SoC/ASIC software development at major corporations. After the panelists discuss their issues there is a 30 minutes audience questions and answers session.

I was doing video interviews at DesignCon 2012 in Santa Clara last week. The event was busy with lots of attendees and presentations. You can enjoy over 20 interviews covering all the advancements in high-frequency IC, board and system design at the following page:
As 2012 begins, it is time to review the stories and weekly articles that were picked by you, the EDACafe.com audience, as the most interesting and newsworthy. We have grouped them by the highest number of click-throughs or readers.
The EDA Weekly Magazine covered many different technology and business topics. The top Magazine article of 2011 was an analysis of SpringSoft, written by Russ Henke.
EDACafe has also been tracking Press Coverage throughout the year. The leading articles were a mix of customer wins, acquisition announcements and business reports, with Tanner EDA topping the list. Here are the most newsworthy corporate stories for 2011:
Synopsys hosted the 24th EDA Interoperability Foum on Nov. 30 and I had the pleasure to attend the event. We listed to keynote speakers who highlighted what has changed in the last decade and what are the next challenges to be taken on. I interviewed Rich Goldman VP, Corporate Marketing and Strategic Alliances, who gave his summary of the event and the highlights from the keynote speakers. You can listen to it here.
I also took some photos which you can see below.
Yatin Trivedi also spoke with Rich for a recap of the event. You can see the video here:
Don’t miss Mark Gilberts’ latest column for Careers Corner and More. You will enjoy reading Mark’s thoughts on moving your career forward even as we near this time of the rolling year. You can see his thoughts and recommendations here.
I was at International Conference on Computer-Aided Design (ICCAD) at the DoubleTree Hotel in San Jose this week and spoke with the General Chair, Joel Phillips about what is trending for the event. You can listen to the interview here.
I have a Computer Science degree from Carleton University in Ottawa, Canada which I received in 1984. Today, I am no longer doing software development or engineering work. In the area of Computer Science, there are many talented and hardworking academics who continue to advance the state of the art. One of those is Reiner Hartenstein, Professor of Computer Science, at the Technical University of Kaiserslautern on Germany.
I have never met Dr. Hartenstein, but I became acquainted with his work by chance. I am on Mentor Graphics’ email list for the various events and seminars they offer throughout the year. For some reason, the emails are addressed to Reiner Hartenstein (...Dear Reiner Hartenstein, Please come to….). I have made several attempts to have Mentor rectify the error, but to date I have not been successful.
Since Mentor had pointed out Reiner to me, I decided to do some digging with my favorite search engine and I was quickly led to Dr. Hartenstein. He is a professor at the University of Kaiserslautern, Germany, and was a visiting professor at UC Berkeley. He is a consultant and expert in EDA tools, creator of the language KARL hardware and a pioneer in VHDL and Verilog languages. He has numerous awards including being an IEEE Fellow, and has published 14 books and over 400 technical articles, and has given over 200 lectures worldwide.
Dr. Hartenstein is focused on the important area of Reconfigurable Computing (RC), typically done with FPGAs. The reason the area is important is because of the tremendous energy savings that are possible over traditional von Neumann, CPU-based computing. For some programming tasks, FPGA systems can reduce energy consumption by 3,000 times according to Dr. Hartenstein. One of the challenges for the introduction and adoption of RC is education: there is a lack of tools and methods that can be used in colleges and universities to teach effective RC.
