Video and Tech Paper: Simulating Large Systems with Thousands of Serial Links

Wednesday, February 29th, 2012

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.

Reinventing the EDACafe Weekly

Thursday, February 23rd, 2012

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.


Panel on HW/SW Co-design from the Software Perspective, Mon. Feb. 27

Tuesday, February 21st, 2012
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.

• Paul McLellan, EDA Industry Analyst and Author, EDA Graffiti
• EDAC Emerging Companies Committee
• Michael James, Senior Staff Engineer, Lockheed-Martin Space Systems Company
• Atul Kwatra, Principal Engineer, Intel corporation

DesignCon 2012 Video Interviews and Photo Gallery

Friday, February 10th, 2012

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:

I also took the time to walk the show floor and take photos of various booths and attendees at the event.  You can enjoy the gallery below.

Happy Valentines Day!
